[QUOTE="Bowhunter1661, post: 387215, member: 9937"] This afternoon I went out to the kankakee river for a little fishing. While out I hit a rock while idling, luckily I had the release up. When I got back to the launch I found no damage from the rock. The damage I found was from one of the two output shaft bearing cap screws missing. It had backed out and chewed through the back of the prop. So here's my dilemma. The boat has good acceleration, cruises at 23 mph with me and my year, 17-18 with two guys. Btw this is a 1992 Evinrude 9.9 converted to 15. The prop on the boat is an aluminum 9.5x10. my rpms are 6330 at full throttle, manual says 5500-7000 rpm. BUT.... It is rated 15 hp at 6250 rpm. So do I go ahead and buy a solus 9.25x10 stainless and stay at 6330 rpm? Or do I go to say a 9.25x9 to increase rpm. Or 9.25x11 to try and get a little more "speed" out of it? Here is my boat, it isn't lite either. Front and rear decks out of aluminum, 3gal gas can, battery, trolling motor and my tackle bag and rods. [/QUOTE]
