Boat repair around Renton.
South Lake Washington
Renton sits at the south end of the lake, with home docks along the shore and one of the area’s busiest public launches at Gene Coulon Park. We work at docks and in driveways all over town.
Trailer boats
Plenty of Renton boats live on trailers. That is easy for us: we service them at home, so there is no launching and no towing to a shop.
Pre-season and pre-trip checks
A quick check of batteries, impeller, belts and fluids before the season, or before a big trip, catches most of the problems that strand boats at the launch.

Can you service my boat on its trailer in Renton?
Yes. We service trailer boats in the driveway, so there is no need to launch or tow it anywhere.
Do you come to the launch if my boat will not start?
Yes. Send a request with the launch and the problem; urgent requests are answered 24/7.
