>> I bought a 2002 Catalina 320 at the end of season last year. I have been following the emails and responses here and have learned quite a bit already. Thank you all who participate.

>> I'm not a "motor guy" , but I love sailing on the Chesapeake. I could use some guidance regarding my Yanmar diesel. I try to top it out at around 3100 rpm's but seem to be getting very little power. Max at around 4 knots. Also the bilge pump runs pretty often while under power. I have had the prop cleaned recently and the bottom was washd in Oct 2011. I had one episode where the overheat alarm went off. I continued to run the motor a short time while it was overheated trying to determine the problem. I shut it off to check the seacock and temperature went back to normal after starting again. I believe something must have clogged the intake. So far since then it runs at normal temperatures.
