About Us

Deep-Water Expertise on the Cumberland

Marine Assist Lake Cumberland was built for one reason: to give boaters on Lake Cumberland a trusted, skilled repair shop that actually understands what happens out on the water.

We're not a one-trick mechanic. Whether it's a stubborn outboard that won't turn over, a lower unit that's seen too many sandbars, or a full seasonal overhaul before winter storage — we treat every boat like it's ours.

What We Do

Services Built for the Water

From quick fixes to complete engine rebuilds — we cover everything between the dock and the deep water.

Outboard Repair & Rebuild

Complete outboard service for all major brands — Yamaha, Mercury, Honda, Suzuki, and more. Bottom-end rebuilds, carburetion, ignition, and performance tuning.

Diagnostic & Electrical

Electronic fault codes, wiring harness repair, charging system checks, and navigation electronics. We find the problem — not just guess at it.

Winterization & Storage Prep

Get your boat ready for the off-season the right way. Fogging, fuel stabilizer, lower unit drain, and proper encapsulation so spring start-up is smooth.

Seasonal Maintenance

Oil changes, filter replacements, impeller swaps, prop inspection, and general tune-ups. Preventive care that keeps you on the water longer.

Lower Unit & Prop Service

Gear oil changes, water pump impellers, propeller straightening and balancing, and shaft inspection. Save your lower unit before it becomes a tow.

Trailering & Transport

Bolt-on trailer repairs, bearing repacks, brake service, and winch stand fixes. If it rolls on water, we make sure it rolls safely on land too.
