Hello everyone. I have a 1979 evinrude 70 hp motor. I couldn't get up on plane and it had a 13 1/4 inch x 17 prop. I changed prop to a 13.5x 15 inch. I can finally get up on plane. My problem is I really have to baby the motor after I put it in gear. Just a little throttle at a time and it is a little rough running at times. When I get to where I can go full throttle it kindof stammers and boggs a little bit then all of a sudden it picks up and runs fast and I get up on plane. At that time it runs pretty good it has just a small miss feel to it. Any suggestions as to why it runs pretty rough getting to WOT then all or a sudden just takes off? I have no ideal. It runs pretty good at idle too. High idle and all works good. Thanks in advance.
