This oil catch can is a must have for any Sea Doo 300\/325hp model.  Your factory crank case vent is routed back into the intake tube.  With crank case pressure and suction from the engine, oil will start to be pulled from the bottom end and enter the intake tract.  This is not good for sensors, spark plugs, superchargers, the engine, or good for performance.   Going with our closed loop catch can design will virtually eliminate the oil entering your intake. USA made\/welded at our Wisconsin facility and specifically for the Sea Doo 300\/325hp Models Closed loop design is much better than an open filter as it does not allow for dangerous fumes to enter the hull, and makes less mess.  Some fuel\/oil can still be returned to the intake tract in the right conditions, but this is extremely minimal if you keep up on emptying the can. Closed loop design also uses the intake suction to create a negative crank case pressure for better power and lower crank case pressure Welded custom barb fittings.  No AN type fittings, any catch can using these fittings restricts flow and will increase crank case pressure Baffled internally to keep oil from sloshing Easily mounts to the frame rail using factory bolting points\/bolts Catch can is mounted towards the back of the vehicle and out of the way, and not near any warm components.  It's not seen when removing the seat, but our long drain hose with valve allows for easy draining without removing the under seat plastic. **Please note the current image shows a screw style drain valve off the bottom of the can, this is not accurate.  ** Lever style drain valve makes emptying easy.  Just open the valve and drain into a container of your choice near the bottom of the hull. We suggest emptying after each tank of fuel or more often.
