Questions

Frequently Asked Questions

Do you come to my marina or boat launch?

Yes. We come to your marina, ramp, dock, or storage facility. Occoquan, Potomac River, Belmont Bay, Lake Anna, Fairfax County marinas — if your boat is there, we can service it. No trailering needed.

What types of marine engines do you service?

Outboard motors (2-stroke and 4-stroke), inboard engines, I/O (inboard/outboard) sterndrives, and outdrive systems. We work on Mercury, Yamaha, Honda, Evinrude, Johnson, Volvo Penta, and most other major brands.

Can you handle winterization before the boat goes into storage?

Yes — our boat winterization service covers antifreeze, fuel system treatment, fogging, water pump inspection, and storage prep. We also do spring commissioning (de-winterization) when you're ready to get back on the water.

Do you offer propeller service or lower unit repairs?

Yes. We do propeller installation and replacement, lower unit fluid changes, propeller shaft seal repair, and lower unit diagnostics. Bring us the part numbers and we'll confirm availability before your appointment.

Is there a deposit to book a marine appointment?

A $25 refundable deposit locks in your appointment slot — it goes toward your final invoice and is fully refundable with 24 hours notice. You can also request a quote without a deposit and we'll confirm availability by phone.

What customers say

Battery died in my driveway at 7am. Matt was there by 8:30, tested the alternator too, replaced the battery on the spot. Cheaper than I expected.

— Mike R., Fairfax

Check engine light had been on for weeks. Matt ran the diagnostic for $79, explained every code in plain English, fixed the O2 sensor same day.

— Danielle K., Chantilly

Matt showed up right on time, diagnosed the starter in 10 minutes, had the truck running before lunch. Way easier than a shop.

— Sarah M., Centreville
