Sea-Doo GTX RXP RXT Jet Ski 2016 Service Manual

Boating Mag's own launch coverage frames 2016 as a genuine engineering leap for BRP: the new 300-hp Rotax 1630 ACE engine arrived across the RXT-X 300, RXP-X 300, and GTX Limited 300 — the first time Sea-Doo pushed a production personal watercraft to this power level, continuing what the brand calls its "Science of Fun" development philosophy. It's a genuine step beyond the 260-hp models that continued alongside these new flagships in the same model year lineup.

Power comes from the supercharged 1,630cc Rotax ACE inline-triple, and Boating Mag's coverage details exactly how BRP got there: an entirely redesigned supercharger with a faster-spinning 32-blade wheel — double the blade count of the previous unit — delivers 30% more intake boost to feed the larger engine's increased air demand. Every 2016 model across the lineup also gained BRP's second-generation iBR (intelligent Brake & Reverse) system, a genuine refinement of the braking technology Sea-Doo introduced back in 2009 as the first braking system ever fitted to a personal watercraft.

The Ergolock seat, first introduced on the RXP-X 260 back in 2012 alongside the T3 hull design, became standard across all RXT and GTX models for 2016 — designed specifically to "lock" the rider onto the machine for confident control during aggressive turns and rough-water riding. Boating Mag's own coverage highlights another genuine comfort upgrade: many models in the 2016 range received a redesigned storage area delivering up to three times the overall storage volume of the outgoing generation — a meaningful practical improvement for owners using their craft for day trips rather than pure performance riding. Sea-Doo forum discussion from launch noted the new superchargers were engineered to be maintenance-free, directly addressing a well-known reliability complaint with prior-generation supercharger units. The range also included Adjustable Trim Tabs, a Bow Stabilizer, and Adjustable Ergonomic Steering (A.E.S.) on select trims, rounding out a genuinely comprehensive update across the flagship RXT, RXP, and GTX lineup that year.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2016 GTX/RXP/RXT running the way it was built to.
