What We Actually Do When Your Ski Comes In

The first thing we do when your ski lands in the shop is plug in the scanner. Sea-Doo, Yamaha, and Kawasaki all have electronic control units that log fault codes, and those codes tell us exactly where to look. Guessing wastes your time and money. We don't do it.

After the electronic scan we do a hands-on inspection — compression test on every cylinder, fuel pressure check, cooling system flow test, visual inspection of the pump, impeller, and hull. We're looking for the root cause of the problem, not just the symptom. A ski that overheats might have a blocked cooling passage, a failed thermostat, a worn impeller, or a combination of all three. The scan and the mechanical check together tell us which one.

Common Problems We See Every Season

If you're riding out of Jamaica Bay, the Sound, or the Jersey Shore, saltwater takes a toll. The problems we see most often are not random — they follow patterns specific to each brand and how the ski is used.

Won't start or hard to start — usually a fuel system issue (old fuel, clogged injectors, failing fuel pump) or a battery that's been discharged too many times. Sometimes an MPEM fault on older Sea-Doos. We scan first, then confirm mechanically.

Overheating / limp mode — blocked cooling passage from sand or debris is the most common cause. Thermostat failure and a worn impeller that's not moving enough water are also frequent. We flush and inspect the entire cooling circuit.

Power loss or rough idle — can be spark plugs, fuel injectors, compression loss, or a supercharger that's started to slip on the charged models. We'll know within an hour of the ski being on the bench.

Won't reach top speed — often a jet pump issue. A chipped impeller or worn wear ring will cost you 5–10 mph and you'd never know until you pull the pump and look.

We've seen all of these hundreds of times. When you call us, tell us exactly what the ski is doing — or not doing — and we'll have a pretty good idea of what we're dealing with before it even shows up.

What You Get After the Diagnosis

Before any work starts, you get a written estimate. Specific line items, not a rough ballpark. If we find additional issues during the repair, we call you — we don't just fix it and surprise you at pickup. The estimate we give you is the bill you pay, unless you've approved something additional.

Most repairs take a few days to a week depending on parts availability. We'll give you a realistic timeline when we have the ski on the bench, and we'll keep you posted if anything changes. We don't like making promises we can't keep.
