Need help with this one !!!!! Let me start with what i have done . New prop correct pitch, clean carbs 3 times , check for spark all 3 are good . Good compression
Ran engine on remote tank no difference to rpm . Checked main fuel line to motor filter all good. changed out fuel pump. Changed all 3 spark plugs again , And all are burning correctly . Did a link and sync and timing is between lines on cdi box. Engine runs great at idle and through its range up to 3000 rpm which is wot ???? . No bog just Does not have that mean power sound of an outboard @ wot, I bought this boat end of last fall when i took it out it was having this problem so i have never had this on plane and have gone through the steeps all summer . Any input would be great
