I need to know if Polaris ever made a 300-350cc liquid cooled 4 stroke single cylinder engine. So far I have only found the 335, 330 and 325 4 stroke engines and they have all been air/oil cooled. I have also found that the 250 and 300 2-strokes were only air/oil cooled. The only Liquid cooled engines I have found are the 400 2-stroke, the 500 4-stroke and the diesel. I am not worried about the twin cylinder engines. Am I correct or am I missing some? Thanks.

 

Nope 350 was a 2 stroke.

 

Was it air/oil cooled or liquid cooled? Thanks.

 

Liquid they bored it out to get the 400

 

you missed the 425 4stroke liquid cooled.The very first Polaris 4stroke which is the same thing as the 2000- 03 400Sportsman

They bored that one out to make the 500 and bored it out less to make the 455. That's what I've been told by dealers anyway. Great engines IMO.

 

Thanks you guys, so there was no small displacement 4-cycle liquid cooled engines.
