I have an older outboard with the 17mm crank, (thick front housing flange). I also have a 9000 7.5cc ducted fan engine. I know the front housings are different as the ducted fan engine has the older set screws for the carb, but is the piston and sleeve EXACTLY the same, timing, etc? Thanks for your help.
When will the new piston and sleeves for these engines be available?
