I have an '84 Suzuki, and lately, and especially after replacing the impeller, Dec 2019, in addition to normal exhaust
stream, i am getting water
coming out from the back of the power head
. It appears to be a vertical tube next to spark plug
holes. Water comes out the bottom of it. Bottom engine
housing "cowling" has a drain hole where this water drains, but one time it got clogged with oxidized aluminum
chips and lower spark plug
got flooded and I ended up limping back to the boat
on one cylinder. I don't remember ever having a drain hose there but i know some Yamahas and suzukis have the extra drain hose from a nipple that comes out of the power head
and some refer to it as telltale hole.
Is this normal behavior on an older suzuki?
I fear that with the engine
being so old, aluminum
power head is oxidized and water might be going places it was not mean to go. compression
is still good and spark plugs look good when pulled for inspection
. Starts on first pull, which i believe is a good indicator I dont have water in cylinders.
