[Public-list] Naive Diesel Questions

[dickdurk at atlanticbb.net]

Maybe I can help with some of your questions-my yanmar is 
seawater cooled, it has petcocks that I could use to 
winterize, though I don't go that route. That suggests 
yanmar has a way to drain the seawater side of yours, 
which would still leave the problem of winterizing the 
water lift muffler.

If you have a radiator cap you have freswater cooling. You 
also have a couple of pencil zincs that need to be 
maintained and two cooling water pumps, one fresh and one 
seawater. What you take for an expanasion tank is almost 
certainly where the cooling tubes are-there should be some 
accessable zincs there also

I wouldn't risk it. The engine compartment will get well 
below freezing many times in the winter. A heat source is 
a possible solution. I've been wanting to check out the 
heat sources pet stores sell for reptiles, myself. About 
$35.00. That way a bulb won't burn out at an inopportune 
time...

I hope there is something you can use in all this
