Boat Engine Repair in Cape Coral, FL
From hard starts to overheating, we diagnose and fix outboard, inboard, and sterndrive engine problems right the first time.
An engine that won't start, runs rough, or overheats can end your day on the water before it begins. JD Marine Service diagnoses and repairs outboard, inboard, and sterndrive engines across Cape Coral and Southwest Florida — and we tell you what's actually wrong before any work begins.
Jeff personally handles every engine job, from compression testing to complete rebuilds. If a repair doesn't make financial sense — for example, when replacing a part outright is cheaper than rebuilding it — he'll tell you that too. That's the honest approach our customers talk about in their reviews.
