[Alberg30] overheating

[schuylki at vanent.vanebros.com]

A 5 PSI drop in oil pressure is normal when an engine comes up to 
temp.-say, 40 to 35 PSI.. A method I use to test coolant temperature is to 
stick my hand in the overboard discharge. Come to think of it, raising the 
thru hull would make that easier....You don't say if your engine is fresh 
or salt water cooled, but doing that , and with a temp gauge, can give a 
lot if info- like if it's cool and the engine is hot, you've got exchanger 
problems. Hard to see how exhaust back pressure could overheat the engine. 
Even if the quarter wave was even with the deck, PSI would be less that 5 
lbs. Way less.
