I had a ‘77 20cc with a 225 Evinrude on it was terrible to get on plane and once on plane took off like a rocket wasn’t much in between (bought the boat that way)installed the largest hydrofoil I could find at the time and it made a tremendous difference! Wish I could / would have tried a 4 or 5 blade prop on it but that’s hind sight. I put one on my 23’cc with the 300 etec and it helped get more stern lift and then the 4 blade prop completed what I think it needed
