Rotax jet (Sea-Doo / BRP)
BRP/Rotax-powered Sea-Doo jet boats and PWCs. Light, lively, and fuel-efficient; supercharged variants (300 hp) require disciplined supercharger service. Jet-pump wear and the closed-loop cooling are the inspection focus.
Service and what to check
Supercharged units: rebuild the supercharger on schedule (washers wear). Inspect the jet pump and wear ring; check for cavitation damage.
Watch usage: above roughly 100 hours/year, this family starts losing reliability points — always weigh total hours against the boat's age, and on any outboard or I/O over a few years old, insist on a compression or leak-down test before money moves.
