Engine Diagnostics & Repair
Comprehensive diagnostics and repair for outboard and inboard marine engines — from routine maintenance, compression testing, and advanced troubleshooting to engine repairs, engine swaps, and performance testing. Backed by years of hands-on marine mechanical experience.
// Overview
What we do
We provide maintenance, diagnostics, and repair for both outboard and inboard boat engines. If your engine won’t start, stalls, overheats, runs rough, loses power, triggers a warning alarm, or develops other performance issues, we identify the cause and perform the necessary repairs.
Our services include scheduled maintenance, diagnostics, compression testing, replacement of worn or failed components and assemblies, engine repairs, and adjustments. When necessary, we also perform engine swaps.
After the work is completed, we test the engine and serviced systems to make sure everything is operating properly and your boat is ready for the water.

Engine Swaps & Repowering
Complete engine replacement — from removal to final testing
