📞 (727) 871-3668 — Free EstimateCross Bayou Is Shallow, Grassy, and Hard on Lower Units
Boaters running Cross Bayou and the surrounding tidal creeks know the drill — watch the tide, trim up early, and pray your prop isn’t about to meet a sandbar. Lower unit strikes are Largo’s most common marine repair call. We stock common lower unit seals, prop shafts, and gear oil for same-day turnarounds.
Serving Largo Boat Owners Since 2010
Largo is a hub for boat storage and service in mid-Pinellas County. The Cross Bayou Canal provides ICW access from the Gulf side, while the eastern portions of Largo connect into Lake Seminole and the larger bayou system. Most Largo boaters keep vessels in dry storage or on private lifts, running them to Indian Rocks Beach and the Gulf beaches via the Intracoastal.

Frequently Asked Questions — Marine Services in Largo
Do you come to boat storage facilities in Largo?
Yes. We service boats at dry storage facilities, in private driveways, and at slips throughout Largo. Mobile service means we work wherever your boat lives — you don’t haul it to us.
My lower unit took a hit on Cross Bayou. Can you assess the damage?
Yes — lower unit strikes are extremely common in shallow tidal waterways. We inspect for bent prop shafts, seal failure, and gear damage, then repair or replace what’s needed, often same-day for common failures.
How often should I change gear oil in my outboard running Largo waters?
Annual gear oil changes are standard maintenance — more often if you run in weedy or shallow areas where debris can nick seals. Contaminated gear oil (milky appearance) is an early warning sign of seal failure we catch before it becomes a full lower unit rebuild.
Can you service an older Yamaha 4-stroke in Largo?
Yes. We service all major outboard brands including Yamaha, Mercury, Honda, Suzuki, Evinrude, and Tohatsu. Older motors often just need a fresh set of spark plugs, a clean fuel system, and an impeller — significant improvements for not a lot of money.
