Twin Yamaha F115s on a bracketted 23'?

[eggsuckindog]

I beg to argue Chuck. My 1978 CC with a bracket will plane with a single 115 and that's swinging a 24" ss Suzi prop. You need tabs down, 1 motor tilted slightly and at 4400 rpm's she'll make 14 1/2 knots.

The 115's will make 25.5kts at 4000 rpm's and 39kts at 5950 rpm's. with 3/4 fuel and 2 people. If you have 6 people and lots of ice I see 25kts at 4300 rpms and fast cruise of 32kts at 5k rpm's.......and that's on 9 year old Suzi's!!!!!!!!!

Zukes run a lower gear ratio in the LU, not sure but might make a difference. 2 115's is only 230 at best as they are 4 S Yami's, I don't think its enough either.
