What our customers report

★★★★★

We run six center consoles out of Jacksonville and every one gets serviced here. Their diagnostic reports are more detailed than what the dealer gives us, and turnaround is consistently under 48 hours.

Capt. Ray Luff Fleet Manager , St. Johns Charter Fleet
★★★★★

Brought my 23-foot bay boat in for a bottom job and electronics upgrade. They installed the chartplotter, wired the transducer, and had the hull painted in three days. Everything was documented and priced exactly as quoted.
