Boat repair around Mercer Island.
Private-dock boat maintenance
Most Mercer Island boats live at a private dock behind the house. That makes the island ideal for mobile service: oil changes, impellers, tune-ups, battery checks and seasonal service all happen right there.
East Channel and West Side
From the East Channel to the West Side facing Seattle, we reach docks all the way around the island. Larger cruisers, tow boats and day boats are all part of the work.
Winterization and spring commissioning
Island boats sit through winter at the dock. Winterization is a flat $150 for any boat, and in spring we bring it back to service before the season starts.
