I've got a 1966 Evinrude 9.5 HP which I bought used. Runs pretty well. I had it out a couple of weeks ago and had no issues. Had it out again yesterday with a heavier load in the boat; after running about for a bit at full throttle the prop thrust pratically disappeared and engine rev'ed up. I backed way off on the throttle to slow and prop thrust was fine. However as I tried to give it more throttle, engine would rev up again adn I'd lose thrust. I was able to move about fine at slow speed. Thoughts?
