Dennis helped me and did a great job changing out my water pump and impeller on my 15hp Mercury 4 stroke boat motor. He did it same day to my surprise. Just ask for Dennis he is a professional. Customer satisfaction is a big deal and that’s why I gave him 5 stars ⭐️ ⭐️⭐️⭐️⭐️ Sincerely : Jim Bounds

Went in because my boat wouldn't go into drive. He ended up finding out why and a whole bunch of other stuff that my last mechanic did wrong. My boat has been running so rough for so long that I guess I just got used to it. Now it's so smooth that it's like having a brand new boat again. 10 out of 10 would recommend. Best in town.

Dennis is a great mechanic and an even better person! I bought a used boat that had sat for 3 years so I wanted him to go through the 150hp Yamaha engine and he did a great job of getting it fishing ready!

Interstate Marine and Outboard is the only place I will take my ancient boat. Not a lot of boat places in Bell County work on 30 year old boats. Dennis is honest and has the most competitive prices around. Even during peak season, he was able to do a two week turn around time. I highly recommend this place.
