Mobile Boat Repair + Marine Diagnostics
When a boat will not start, overheats, alarms, loses power or simply is not running right, Keelmark brings professional troubleshooting directly to the boat or marina.
Find the cause before replacing parts.
Engine + drivability diagnostics
We troubleshoot no-starts, hard-starts, intermittent faults, warning alarms, ignition and fuel problems, cooling-system failures and loss-of-power complaints.
Mechanical repair at the boat
Once the fault is identified, we handle practical repairs on inboard, sterndrive and outboard-powered boats whenever the job can reasonably be completed dockside.
Overheating + cooling systems
Raw-water pumps, impellers, hoses, thermostats, heat exchangers, risers and related cooling-system problems are common Greater Seattle service calls.
Keelmark provides mobile service across Seattle, Bellevue, Kirkland, Mercer Island, Renton, Shoreline, Lake Forest Park, Kenmore, Redmond and Sammamish. Send your boat • marina • problem with photos or videos when possible and we’ll confirm availability and the best next step.
