Re: Universal M5411 Engine 11HP
I have a 5411 in my Ticon 30, similar in size to the Catalina 30.
If you read HP requirements by displacement is shows under powered.
Hull speed is 6.8 kts. my top speed under power is about 6.2 (2200 rpm)and it settles in very nicely at about 5-5.5 (1900-2000 rpm).
My max RPM should be higher, I have not checked for partial blockage in the exhaust pipes or for any of the other usual suspects, maybe next season.
