Just a reminder ... My first hint that there was a problem was when my rubber diesel fuel line started to crack ... ONLY in the motor compartment. And I didn't do a lot of motoring. So it had to be a heat problem. I don't remember my first J30 (a #300 something) that well, but the inside of the motor cover on #505 is covered with a sound insulation blanket ... probably insulates for heat as well. This problem probably doesn't matter short term ... but I've had #505 23 years so I sort of take a long term view. Like when I destroyed my first impeller on the water pump at the 15 year point. (power sailing on starboard tack heeled sucking air) They tried to sell me a spare ... "always need a spare impeller!"
I said no way ... this one only blew because i screwed up sucking air ... and I got 15 years out of it ...
I have it on my maintenance schedule to replace the impeller in 2015.
