I bought my 2009, Catalina 309, hull #168 on July 16th, 2010 and finally got to use the boat for the 1st time. My wife and I sailed for the last 3 weeks and had a great time, however, I am wondering how the 21 hp yanmar performs on other 309's.
The owners manual says max RPM is 3800, my boat's max is 3400 and the top end seems a bit slow, here is the basic performance:
RPM Speed
2000 3.5
2500 4.3
2700 4.55
2800 4.65
3000 4.9
3400 5.15
Shouldn't top speed for this boat be 6+?, these readings were taken with a very light cross wind. I bought the boat with 42 hrs on it and put 30 hrs on it in the last 3 weeks.
The yanmar ran well and sounds real smooth which is more important than the top speed, could you please share your thoughts.
