I ran 22" stilleto props on my 23 cc with twin 115's on a bracket. I moved up to 24" props and although they were the same brand and model, the bow now runs amazingly flat. I would fool around with another 17" prop. That is a very popular model so finding a buddy to lend you his shouldn't be a problem.

Filling your boat with lead or using a doelfin while useful is merely a bandaid for your problem. You may have broken a baffle in your fuel tank. Try swapping props and get back to us.
