I guess I am gonna get hammered here. I personally really like the sportster 65. It will not have the screamer performance that say an Irvine or OS 61 will. But oh lord will it swing a big prop. They used to be called the poor man's four stroke. 13-6 is a minimum on this motor. I have used 14"ers on it with no problems. Prop it so it tops out a little over 9000 rpm max. You will love it. Great where you need lots of pulling power. And with the factory muffler very quiet. It is also fairly light for it's size. Do not be afraid of it. It is a decent engine for the money. Just do not try to make it something it is not.
