[QUOTE="Zum, post: 503186, member: 349"] With that little tunnel your going to lose alittle top end speed as well...like mentioned above, 25mph. That 13" prop is probably alittle big, especially with a load, bet an 11 or even a 10 would put you in the top end of the rpm range of your motor(where you want to be) I have a 30hp(old 2 stroke) on a 1652(with wlittle tunnel)...a 13" prop is what I put on if Im by myself and a light load...normally use a 11ish(think 10.75"). Its been awhile since Ive gpsed but think 29mph with the 13 and 26 with the 11. The 13 is even alittle bigger then i want by myself, I like to be at the top range of rpms for my motor. Raise her up alittle but make sure it pumps good water, I know with my tunnel I can go to high...I needa compression plate or low water pickup. [/QUOTE]
