JSN1200 Engine

JSN1200s are built on order.  There is a 90 day lead time for all JSN1200 engine orders though delivery times are typically faster.

The JSN1200 is the pinnacle of freestyle jet ski performance.  Featuring the world famous CPI cylinder, the JSN1200 is the most powerful 1200cc engine in the industry.  We’ve taken the cylinder that changed the jet ski industry and paired it with an engine package thats reliable and easy to maintain.  Power delivery is linear and controllable – but don’t worry, these engines are SERIOUS arm rippers.

We’ve taken the guess work out of buying a pro-level 1200cc engine.  There are no comp packages, no special configurations and no custom parts.  All JSN1200s are built the same way with the same porting configuration and parts.  The engine you buy from us is the same engine our sponsored pro riders run.

Every engine comes fully assembled and pressure checked.  You’ll have access to a full build profile with every spec down to what type of case sealant was used on our website.  Looking to buy a used JSN engine and not sure how it was originally built?  We’ve got you covered – you can simply enter the engine serial in our engine catalog and find every detail of how that engine was originally built.
