Lower Unit & Gear Repair in Cape Coral
Specialized lower unit service including rebuilds, seal replacements, and gear work for all major brands.
Your lower unit takes the most abuse of any part of your boat — sand bars, fishing line around the prop shaft, and Southwest Florida's shallow flats all take their toll. JD Marine Service handles lower unit rebuilds, gear replacement, and seal work for all major brands.
Caught early, a leaking seal is an affordable fix. Ignored, water in the gearcase grinds gears and bearings into an expensive failure. If your gear oil looks milky or your shifts feel rough, have it looked at before the damage spreads — and if a replacement unit is more cost-effective than a rebuild, we'll be straight with you about it.
