What We Actually Fix — No Job Too Big, No Problem Too Weird
St. Pete boat owners deal with everything: Tampa Bay’s shallow sandy bottom tears up lower units, saltwater fries wiring, UV destroys gelcoat, and Florida’s heat pushes engines past their limits. Here’s what comes through our shop.
Engine Mechanical Repair
Overheating diagnosis, impeller failure, fuel system problems, compression loss, timing issues, and full engine rebuilds on outboards and stern drives.
Marine Electrical & Wiring
Starting issues, charging system failures, corroded wiring harnesses, bilge pump wiring, navigation lights, and NMEA network troubleshooting.
Lower Unit & Drive Repair
Gear case leaks, prop shaft damage from hitting the sandy bay bottom, seal replacements, and full lower unit rebuilds.
Fiberglass & Gelcoat
Impact damage, stress cracks, transom rot, osmotic blisters, and full gelcoat restoration. Structural repairs done right — not just cosmetically patched.
Fuel System Service
Ethanol damage is real in Florida. Fuel injector cleaning, carburetor rebuilds, fuel tank inspection, VST cleaning, and vapor separator service.
Steering & Hydraulics
Hydraulic steering leaks, stiff helm, cable steering replacement, trim system failure, jackplate issues, and tilt/trim motor repair.
Why St. Pete Boat Owners Drive to JG Coastal
There’s no shortage of marine shops in Pinellas County. Here’s what’s different about us.
We diagnose before we sell you parts. The most expensive mistake in marine repair is guessing. Before we touch a wrench, we run the engine, pull codes, and trace the actual fault. You get a written estimate with the root cause — not a parts swap hoping something works.
We work on what others won’t. Old Mercruisers, rare Japanese outboards, twin-engine setups with intermittent issues, fresh water damage from Tropical storms — we don’t turn away the hard jobs.
Straight timeline, straight price. We know your boat is tied to your weekends. We quote realistic turnaround times and stick to them. If something unexpected comes up, you hear from us before we touch it.
14+ years on Tampa Bay. Jared has been working on boats in this area since 2010. He knows what salt air does to wiring after 5 years, what Tampa Bay’s bottom does to lower units, and why Florida-spec maintenance schedules are completely different from what the manufacturer’s manual says.
We service what you own. Center consoles, bowriders, deck boats, bay boats, offshore walkarounds, and pontoons. Outboard, inboard, and stern drive. If it floats in Tampa Bay, we work on it.
Our Repair Process — From Drop-Off to Launch
No ambiguity. This is exactly how every repair job at JG Coastal works.
You Call or Text
Describe the symptoms. We’ll tell you if it sounds like a shop job or something you can handle yourself. No pressure either way.
We Diagnose
Full hands-on inspection and diagnostic testing. We document what’s wrong, what caused it, and what it’ll take to fix it properly.
Written Estimate
You get a line-item estimate before any work starts. Labor, parts, and timeline — all in writing. You approve it, we start.
Repair & Quality Check
The repair is done, then test-run to verify it’s resolved. We don’t hand a boat back until we’d take it out on Tampa Bay ourselves.
Pickup & Follow-Up
We walk you through what was done and why. If anything comes up within 30 days related to the same repair, call us.
Frequently Asked Questions — Boat Repair in St. Pete
How long does boat repair typically take in St. Petersburg?
Simple mechanical jobs like impeller replacement or fuel filter service usually turn around in 1–3 days. Electrical diagnostics take longer because we need to trace the full circuit — usually 3–5 days. Major repairs like lower unit rebuilds or transom work can run 1–3 weeks depending on parts lead time. We give you a realistic timeline upfront and update you if anything changes.
Do you come to my marina or do I bring the boat to you?
Most repair work is done at our shop in Pinellas Park, which makes for faster, higher-quality repairs — we have the tools, lighting, and workspace to do it right. Call us and we’ll figure out the best logistics for your situation.
My boat just stopped running on Tampa Bay — what should I do?
Get safe first. Call TowBoatUS or Sea Tow to get towed in, then call us at (727) 871-3668. Describe exactly what happened before it quit — rough running, no warning, alarm went off, etc. That detail helps us diagnose faster once we see it.
How much does boat repair cost in the St. Petersburg area?
Diagnostic fees typically run $85–$150 depending on complexity and are credited toward the repair if you proceed with us. Basic jobs like oil changes start around $150–$200. Electrical work varies widely — $200 for a simple fix, $1,500+ for major rewiring. Lower unit rebuilds run $600–$2,000 depending on the unit. We give you an exact number before touching anything.
Do you work on older boats?
Yes — older boats are often our favorite jobs because they have real mechanical character. We’ve rebuilt 30-year-old Mercruisers, sourced parts for discontinued Evinrude outboards, and repaired fiberglass on classic Chris-Craft-era vessels. Age isn’t a problem if the boat has good bones.
What brands do you service?
Yamaha, Mercury, Suzuki, Honda, Tohatsu, Evinrude/Johnson (legacy parts available), MerCruiser, Volvo Penta, and most other outboard and stern drive brands. If you’re not sure, call and ask — we’ll tell you honestly whether it’s in our wheelhouse.
