[C38] overheat

[Max Soto]

Well, the engine works...Perhaps, I just want to believe that it doesn't so
I can get a bigger one!!  LOL

I'm going next week with a spare temp meter and I'm planning to take out the
manifold and reinstall the cap, also planning to service theexhaust flange
on it, since one of the bolts is broken....the, I will start it and see how
it works... If it is ok, I have two choices, buy another engine, and sell
the old one in working condition, or overhaul it and keep it (cheaper!), but
if I sell it, I may recover some of the money spent on the new engine......

It depends on the price of the other engines....   How does  $3200 sounds
for a 1997  27hp Yanmar 3GM30 with 572 hours??
Regards,

Max
