[QUOTE="ditchen, post: 305731, member: 3911"] I have a 1448MV. 1st motor was a 72 25hp tiller johnny, no fun. Then jumped up to a 76 40hp tiller johnny, started to get a smile. Added a cmc pt135 TnT with set back, then prop limitations. I did like the balance of the boat with the big twin, so I obtained a 81 50hp console steer johnny, better. Obtained a 81 60hp johnny. After mods and having the propped stretched with lots of cup, that yielded the sheet eating grin. But once again I am prop bound. Very tough to find a 23 plus pitch SS prop for the small gear case. Light load runs mid to high 40's. Once again prop bound, the motor is pulling to many rpm's I did have a notion to put a triple on it, but did not want the extra weight.
