hello,im installing a yamaha liquid cooled cf300 engine in my max,any ideas for radiator and cooling fan,its a cyngle cyl 28 hp liquid cooled engine,so far everything is going well,just worried about keeping it cool ,any advice would be great

Thats an idea I've been thinking about for years. I would place the radiator high so that it sticks out of the body enough to cool down. A slim line cooling fan with thermostat is all you need.
My idea was to use a Honda 425cc liquid cooled, but haven't decided to go with that or a little Kubota diesel liquid cooled.

Was that a sled engine 2 stroke out of that wacky sled they built back in the eighty,s?,they were a smooth running little engine,check the wreckers any rad with a electric fan out of a small import would do,or the rads they put on the early SRX Yamaha snowmobiles with a electric fan would be fine,set the rad up in a fashion that it has direct access to outside air,and reverse the fan air flow to blow out thru the rad this will serve two purposes it keeps the rad clear of debris and relives under hood temps,good luck with your project sounds like fun,jus not sure whats holding you back from a bigger water eater.LOL Cheers

would have a bigger engine,but the sled was free,got it in and running,waiting for the radiator and fan to show up,only real challenge in getting it piped so i get the back pressure rite,cant wait.thanks for the advice

update,maxII with yamaha 2 stroke runs out great,estimate 30-35 mph,love it even more now.figure if i play with the exhaust and belt will hit 40+ mph.6x6 rule
