Marcus Webb
Operations Manager, Shelter Island YC
"We've tried three other shops over the years. Bilge is the only one that sends us a complete work order before the invoice. The compression numbers don't lie — every engine they've touched has come back better than the manufacturer baseline."

"We run six charter boats out of Harbor Island. Missing a weekend booking costs us $4,200 minimum. Bilge has never caused a missed booking in four years. The documentation they provide is good enough for our insurance audits."

"I subcontract mechanical work to Bilge exclusively. Their documentation is the reason I keep renewing — when a slip holder asks me about a warranty claim six months later, I can pull the original work order, the photos, and the parts list in under two minutes."

Anita Ramirez
Dockmaster, Point Loma Yacht Club
"Our members are particular. They want their boats treated like their cars. Bilge shows up on time, leaves the engine bay cleaner than they found it, and emails the work order before the tech leaves the dock. That's the standard I hold everyone to."

James Treadwell
Owner, Treadwell Sport Fishing
"Commercial fishing operation — downtime is money. They did a full Cummins rebuild in 72 hours, including a 6-hour sea trial. I've had shops take two weeks for half that job. The compression test results they sent over were better than factory."

"We referred Bilge to a slip holder with a Perkins that had been misdiagnosed by two other shops. They found the root cause — a cracked fuel gallery — in two hours. The repair was documented down to the torque value on every fastener."

"Three vessels, all Volvos, all serviced by Bilge for the past six years. They know our engines better than we do. When they flag something in the work order that I didn't ask about, I pay attention — they've caught two issues before they became failures."

"I'm a liveaboard sailor. My engine is my safety system. Bilge treated the Yanmar like it was their own. The work order they emailed me has photos of every component before and after, torque specs noted in the margins. I've never seen that level of documentation from a mechanic."
