I am no diesel mechanic that is for sure. But for the first 4 years I owned the boat I fought overheating. Always happend at the worst times. So I decided to dive in. Torreson was a HUGE help. I was able to solve my prolem for about $60 in gaskets and a new thermostat. It was basically scale buildup and pieces of an old impeller jamming the thermostat. I chipped away the scale etc. put her back together and we had a perfect season together - our first.
I found that the motor is amazingly easy to work on and with the help people like Torrenson and this list everthing was just as explained.
It seems that if it runs and has good compression then everthing else is relativly inexpensive and you can do it yourself.
Can't think of a J/30 that has been repowered.
If you need counseling, Teresa had the same up's and down when she was buying Triple Play.
