[Alberg30] overheating

[FINNUS505 at aol.com]

Interesting and valuable discussion on diesel exhaust smoke color and 
diagnosis of which problems different color smoke indicates, but.................back 
to my question!!! :), anyone see a problem of overheating when powersailing 
on port tack, and the exhaust thru hull is intermitently submerged?

The reason I am not completely sure there was a problem is that my water temp 
gauge was not working consistently on a trip when we had to powersail to 
windward, bucking a current, towing our dink, in order to make port. While I did 
not trust the temp gauge, I noticed oil pressure dropped 5 points or so, and I 
thought that might have been an indication that the engine was overheating. 
When I noticed that, of course we shut down our volvo, and changed destination 
that day to a port we could make under sail alone. I have since put in a new 
water temp gauge, but have not had a chance to powersail on port in enough wind  
to reproduce the original conditions under which I experienced the potential 
problem again, ie; that the exhaust thruhull was submerged for any length of 
time, and so I was wondering if anyone else noticed this problem.  
It will not be much trouble to move the exhaust thru hull up to the lower 
corner of the transom, but obviously, I would rather not have to do it if 
unecessary.
I know there are alot of A30 sailors here that have been sailing these boats 
for a long time, and have been under 'adverse conditions' more than once or 
twice. If noone else has noticed this problem and have been sailing with the 
exhaust thru hull in the standard place all these years, that will be good enough 
for me!!!!!!!  :)
Thx,
