I've got a 15'-4 HS with a 9,5 Rude on it. It does OK but I'd like to see a little more performance. I was going to order a 9.9 Tohatsu 4 stroke but after reading some of the posts on the Site about re-powering the boat with a 15 HP 2 stroke, I've decided that may be the way to go. I've located an 84 15 HP Rude that looks to be in excellent condition (for about $1100.00 less than I'd have in the Tohatsu). So....my question is....what would be y'alls suggestion for a prop?
