I just purchased a 1999 Javelin Venom 17 with a 1978 Evinrude 115 (model #115899), the boat is real rear end heavy (engine, 3 batteries, gas tank and a livewell). When I try to get it up on plane it just pops the front end up, so I had my friend sit on the front deck to get it up on plane. I think it needs a new prop but I am not sure what to get. Also I plan to add a little on to the deck to extend it to the console. This will help a bit, but I am sure it needs a new prop. So if anyone can help me out with what I should get, that would be much appreciated.
