Flushing a Rotax
I am sorry but I just don't get how or where to flush these motors. Researching I've learned they're closed loop but the exhaust has to be cooled while running out of water. I bought a Speedster 150 with no manual and can't find the service manual anywhere.
Just a little background I've come from owning a Yamaha which comes with a flush adapter and everything is pretty straight forward.

Its in the pump tunnel the cooling exit is threaded for the flush.

Have u tried eBay for a manual? Usually there's a flush port on the pump area for a water hose it's for cooling the exhaust and intercooler while out of the water. There's a certain procedure for flushing tho, you have to start the engine then water hose run no more than a minute or so shut the water off and then the engine

Glad to SEA ya and yea there should be a place aroung the back of the jetpump area or on top on one of the sides as you raise the hatch. at least that what i had available. Oh and yea if its SC'd i recommend a "strainer" before for the IC to keep sediment out.

Found it, thanks for the replies.
So just hook a garden hose up to the cooling exit. Anyone know the threaded fitting size so I can make one myself?
