Are they used in Salt, or Fresh Water?

Cracks on the outside ( you'll see rust stains ) . Cracks on the
inside are hard to immediately see. Over heating is a sure sign. Using
clear tubing while idling...do you see any bubbles passing through? I
just rebuilt my 40 year old Risers over the winter. Soaking them in
Pickling Vinegar worked great to clean them out. After that, I scored
out the cracks very slightly with the Dremel, and put a nice coat of
JB Weld over top, followed by a coat of Tremclad white.The finishing
touch was to paint the Exhaust Stubs with High Heat Enamel. They do
look nice now.

You've had your warning. The next one won't be so subtle. Spell
hydrolock, or is it hydralock?

So, you went right from chipping paint on old navy ships to sucking used
lower unit oil out of outdrives?
