Earlier this year I had posted the question of what engine to repower my boat with. Thought I would update.
I have a 2000 Nautico catamaran 18 that had a 50 Honda 4 stroke. Cruised at 16mph, top end of 22 mph.
I went with a 2014 Yamaha F70 . Weight is about the same. With the new motor, cruise is about 26 mph at 4800rpm and wot is 34 mph at 6000rpm. 13 pitch yamaha 3 blade prop. No ventilation issues, ran 6 hours on a 10 gallon tank of 89 octane. Max hp for this boat is 75.
Excellent results so far, this engine was made for this boat!. I had a poor experience with the dealer, but the motor is great. The dealer told me that I can run this motor wide open forever. They did such a sloppy job on install that I wonder if it is true. Anybody?
thanks
