Dr. Dave

Our Customer Lobby...Over 30 Years of Valued Customers!

Brian Burns: Sept 2019 (5 stars)Took my boat in for outdrive repairs I thought I needed, Dave inspected the outdrive and found I did not need to have the outdrive service done at this time and did not charge me for unneeded parts and labor saving me nearly $400.00. I really appreciate his professional opinion and knowing my boat will run properly and be safe on the water. I would recommend Gonyea's for all your boat repair and maintenance needs.

Jeff Burgess:  Sept 2019 (5 stars) Dave and team take care of all my boat concerns. From repairs to winterizing, he is quick and fair. Dave's the only mechanic I've trusted.

Nick Snyder:  June 2018 ( 5 stars)
I've been taking my boat to Dave for about 5 years now. I have a Ski Nautique, and have continually been impressed with his knowledge of every aspect of my boat. He has never tried to charge me for anything that was never needed, and every year he gets the boat purring and ready for another season. While user ratings typically stratify toward 5 or 1 stars, as something usually happens to motivate a user to give a rating in the 1st place, my 5-star rating is based on years of searching for a solid boat service company: I used to use the local Nautique dealer years ago, and they were fantastic, but the local company went out of business. Since then, I've been to the Mastercraft dealer (now Stancraft? on Macadam) and never had an occasion where they didn't try to sell me a boat, Cascade Marine Center, Steven's Marine, and one other in Gresham that's no longer around. Next to the folks at Nautique, Dave has proven to be the most knowledgeable of any of them. While his facilities are not the most polished, he has proven time and again that he can solve issues (e.g., bad kill switch, dealing with E10 gas, tuning) and prevent them from happening through annual service. He even fixed the bunk boards on my trailer! My family loves being on the water, and every year we rely on Dave's service for a fun summer! Thanks for making it happen Dave!

Thane Eddington: June 2019 (5 stars) Dave Gonyea has provided top notch service in servicing my 1980 Sea Ray.  He has always gone above and beyond in ensuring my older boat runs it's best.  He addresses simple yet, important issues such as trailer lights and brake pneumatics, to impeller replacement and engine service. I always feel like he is going above and beyond to make my experience great in the shop when I'm on the water. I highly recommend Dave.

Ellen Stevens: November 2018 (5 stars) With a stressful season upon us, we needed our boat winterized. Thankfully Gonyea's was able to get to us right away, did the work in  an and didn't charge us!  What a wonderful Christmas gift from a man who runs his own business .He'll never know how much that means to our family with only one person working. Dave has done work for us in the past, after a house fire, and has always been responsible and available even during peak season. The ONLY place in Gresham/ Portland Metro to have marine work don is Gonyea's! Thank you so much!!!!!!

Nancy Pinney August 2018 (5 stars) I bought an older 1977 16' Fiberform Boat for my husband to go fishing in 2013.  We had to find someone that knows boats to help keep it in ship shape, shape! Dave was recommended to us by a Marine Boat Store. He is awesome! Would not trust anyone with our boat but Gonyeas'. It is an older boat so needs TLC, we've had some minor issues but Dave always knows what the issue is and gets us back on the water in no time. His process are very reasonable and he takes the time to explain and suggest services that will allow us to hold on to our retro gem. I actually use the boat more than my husband now, taking my girlfriends out on the Columbia.  It's great to know I'm going to going out and not have any problems. Thanks Dave and team for taking such good care of us!

Kerry Hinrichs  July 2018 (5 stars) Dave is a straight-up guy with a big heart and a whole lot of knowledge. He was extremely responsive and explained everything thoroughly and honestly. He is very speedy and went above and beyond to ensure our boat is ready for summer fun. Hoping he never retires, because we can't imagine going anywhere else!

Robert Ramsey October 2016 (5 stars) I have been using Gonyea's for 3 years for both winterization and summer tuneup with great results and no problems.

Greg Button June 2016 (5 stars) I have used Dave twice since I bought a used pontoon boat. He makes home visits and this time made a visit to the lake to diagnose the issue and install a new part. He is timely, professional and provided a quick resolution to fix my vessel. I would recommend Dave to any boat owner. Thank you Dr. Dave!

Ken Owen July 2016 (5 stars)Exceptional service! Took my boat in for a motor problem which out to be a bad starter. They were quick to trouble shoot and replace the starter. He also gave the boat a thorough inspection for any other problems. Gonyea's Marine Service will get my continued business.

Ben Cosigan June 2016 (5 stars) This was my first time going to Gonyeas Marine. I was very pleased. I had just bought my boat and he went over it thoroughly to make sure I wouldn't get stranded on the water. Everyone was very friendly and he kept me updated on the status of it. I'll use them again.

Dwight H. Gresham, OR  ***** (5 Stars)  (or 6 stars if I could!)11/03/2015 

His expertise is absolute! Most honest guy I have ever met. Several year ago I came in for a simple lube,

and he always does a little extra at no extra charge. This guys earns 6 stars by my standards!

Dennis C.  Fairview, OR   ***** (5 Stars) 11/02/2015

Quality, I really like Dave, he gives more than I expect- he gives 120%.  I have used GMS for almost 20 year,

I won't take my boat any place else!

Stan G. Gresham, OR  ***** (5 Stars)  10/26/2015

 Dave understands Tournament  Ski Boats, I have been using Gonyea's Marine Service for 20 Years!

Dale P. Fariview, OR  **** (4 stars) 10/16/2015

  I never give 5 stars because it allows people room for improvement.  I was refered by my neighbor,

and I am glad that I was!

I will refer GMS when I get the chance.

Jeff B. Portland, OR  ***** (5 stars) 10/14/2015

On time & Honest! I will return in the future.

Cory T. Fairview, OR  ***** (5 Stars)  10/12/2015

Dave is reliable and does good work! I will return for all my service and repairs!

Rich H. Damascas, OR  ***** (5 stars) 9/02/2015  

" Dave's my Guy, I wouldn't use anyone else!"

Bob G. Portland, OR *****(5 stars) 10/15/2015

Straight up & Honest! I've been bringing my boat to Gonyea's for 6 years now.  

Dave and his trusty sidekick Mike have been straight up and honest on all advice and repairs,

setting me on a better path multiple times. They started by steering me away from purchasing a certain used boat-for free.

I had lots of questions and concerns that didn't necessarily lead to profits for Gonyea's.

since then, they've rapidly ferreted out a wide variety of challenging issues- engine, electrical, hydraulics, trailering- you name it!

They are always willing to carefully explain what needs to be done and why.

They are a pleasure to deal with, and make customer satisfaction a priority.

John N.   Gresham, OR  ***** (5 Stars) 9/14/2015

(Boat: Thunderjet) Excellent same day service!

I did not get tossed around, prices were reasonable and I received excellent customer service.

Keight K. Damascas, OR ***** (5 Stars)  8/7/15

(Boat: Chaparral) Reliability and Job Performance...

will keep me coming back to Gonyea's Marine Service.  These were two key elements that make me a satisfied customer.

 I will continue to refer people that I know to Dave, and I will be a continued customer .

Ron L.   Boring, OR  ***** (5 Stars)  9/28/2015

(Boat: Reinell)  I appreciate this marine mechanic! 

Dave's knowledge won me over.  I have refered friends of mine to him since my service- because I am a satified customer.

I will continue to use GMS , and Dr. Dave as my boat mechanic.  I appreciate all the work that he did on my boat.

Brad P.  Troutdale, OR **** (5) Stars 08/20/2015

When your boat goes bad, Dave Gonyea is your guy! GMS was very punctual with my boat repairs.

 Usually, when you tell a company to do some repairs, it takes alot longer.  I had bought a used boat,

had them change one of the motors, and one other motor needed service, plus some other work.

 It is similar to when buying a used car, he had to fix a few things for me.

 So, we set up the time and discussed what needed to be done.( My friend who fishes, recommended Dave to me.)

 I had experienced other boat repair companies, but they don't offer as much as Dave Gonyea does.

 If you need any good boat repairs done, go to him!  He is prompt and reasonable.

 I'm a satisfied customer and was provided with excellent service and a very good experience!

Christina F.    Boring, OR ***** (5 Stars) 08/05/2015 Smart, Accurate & Timely!

Dave is the best boat mechanic around, hands down!

 I have been through a few including local corporate repair shops and they don't hold a candle to this business.  

They know older boats as well. I have always been happy with my service, and I will keep coming back.

Wayne S.   Troutdale, OR ***** (5 Stars) 07/07/2015 Service by Dave was fantastic!

Dave @ GMS really is the boat Doctor! I am very pleased w/ the work that he did on my older boat.

There was always a problem with the acceleration.  I had tried different things over the years to correct the problem-

I took it to Dave and he repaired it! My wife agreed that after a trip to Madras that it is running better that ever before.

 His prices are reasonable to! I would not hesitate to recommend him to a friend.

Kirk V.  Sandy, OR ***** (5 Stars)  07/05/2015 Very Pleased!

I needed some repair work done on my boat but, it is difficult to find someone locat that is trust worthy.

And Gonyea's Marine was close and convenient.  I called first and got a fair quote over the phone.

I was very pleased with the service, and the price and I will return.

Mark D.  Government Camp, OR ***** (5 Stars) 7/14/2015

 Dave always does what he says he'll do!

I have been going to GMS to get my boat worked on by Dave for about four years now,

I have never been disappointed with his work... I wouldn't use anyone else!

Alex M.  Gresham, OR ***** (5 Stars) 06/09/2015 Good, Fast, and Thorough!

GMS was able to know when I called exactly what I needed just by the description of the problem.

 They got me in and out the same day-

it was good good, fast, and thorough!

Mark L.    Oregon City, OR ***** (5 Stars) 06/24/2015  Very Good Customer Service, and very good work!

GMS went above and beyond on their cal of duty to get my boat fixed.

 It was kind of a dirty job.  But, Dave didn't hesitate and jumped right in and got the repair work do.

 This was my first time to GMS, and I was pleased.

Allan W.   Seattle, WA ***** (5 Stars)  06/01/2015 Very good!

GMS are excellent when it comes to working on ski boats; they were very efficient and got the job done! 

Mike H.    Boring, OR ***** (5 Stars) 05/22/2015 Excellent!

I have been going to GMS for a few years now.  I am impressed with Dave's passion right away.

 He knows his stuff, and cares about and understands boating.

He and his assistant provide a through checklist with good notes,

so you can feel confident with your repair services.

Clem E.      Sandy, OR ***** (5 Stars) 5/27/2015 Knows what he is doing!

GMS and I just get along well- they do a great job!  They are efficient and get thins done on time.

Dave knows what he is doing!

Darrin T.     Gresham, OR  ***** ( 5 Stars)  05/05/2015 Gonyea's is a good, honest boat shop!

My experience with GMS was really good.  They did more that I expected, and fixed small things I didn't even as for.

 They worked on the motor of my boat to replace a starter and Summerized it.

 Everything turned out better that expected. This company is the best in the industry!

Mel M.    Gresham, OR  ***** (5Stars) 04/21/2015 Great Service, fast turnaround!

My favorite part of GMS is their incredible turnaround time.

 They get the job done quickly for a reasonable price.  Last time, I brought my boat to Dave it was on an Insurance claim,

and they made the entire process of making the claim (which can be hair oulling) painless!

Bob L.    Portland, OR ***** (5 Stars)  11/13/2014 Give them a try!

I have been using GMS for years! With the boat problems I have had they have always been right on the money with their diagnostics.

 Dave does good work; and that is hard to find in the industry. I would recommend others to give them a try!

Protecting Your Investment

Because your boat is more than just a hobby, (it's an investment)  the service and maintenance needs are a important fact, that shouldn't be taken lightly.

NOT ALL REPAIR SHOPS ARE CREATED EQUAL ! You should always be completely confident with where you entrust your boats service & repair needs.

 

Ask yourself these five questions:

 

1.     How were you treated? With the respect that you deserve?

2.     Was your problem addressed and repaired the first time?

3.     Was the repair done sooner than expected?

4.     Was it a quality repair at a reasonable charge?

5.     Was the vessel kept clean?

6.     Do you know the three myths of the boating industry?

If you answered "NO" to any of these questions, you may be compromising the quality care and condition of your fishing, recreational or & ski boat.

 

We encourage you always be prepared, by keeping your vessel in tip-top condition!

 



The Gonyea Difference:


Fish Counts...

Smolt Monitoring (SMP) @ Bonneville Dam-

Sub yearling Chinook continue to dominate the samples at Bonneville Dam this week.

Nearly all (99.9%) are fry. The daily average passage index for sub yearling Chinook fry this week was nearly 1,800 per day, which is a large increase over last week’s daily average passage index of about 300 per day. A small number of yearling Chinook, Coho and steelhead were also collected this week. Approximately 90% of the Coho that were collected this week were fry. Pacific lamprey macropthalmia were encountered in all samples this week, the daily average was 220 per day, which was an increase over last week, (March 26th).

@ John Day Dam (JDA) yearling Chinook dominated the salmonid samples this week, daily average was about 130 per day, similar to last week daily average passage index. Of the yearling Chinook collected this week, approximately 16% were yearling fall Chinook holdovers. Coho and steelhead were encountered in low numbers.
