my 26' tolly has a freshwater cooling system. i put new water lines on
last year so everything is in great shape.

took it out last weekend in the fairway to practice docking. engine
kept stalling at slow speed (600 rpm). got it back into the slip and
found the bilge pump was running. opened the bilge and found the
cooling water line from the throughull to the cooling water pump had
completely collapsed even though it was wire reinforced. the end of
the line had ripped away from the throughhull and water was streaming
in.

i shut the seacock and let the boat pump out put a new water line on,
started the engine and it ran like a charm with no overheating.

looking at the collapsed line...i remembered that the previous week
the marina had filled with seaweed. some of this probably got stuck on
the strainer and blocked the inlet.

before i put the new water line on, i backflushed the strainer with
water and got good flow. but will keep an eye out for seaweed in the
future.

Bob, I dont know how course the strain3er is but I'[d think you'd see
evidence of the sea weed stuck in the hose or the screen. Then again,
i wouldn't think you'd gotten a bad hose but.... still a bummer!

Might want to take out the impeller and inspect it. Better still replace
it. The don't like to run without water.

It's possible that seaweed plugged the strainer on the outside of the
hull (usually the through hull intake has either an integral strainer
or a domed strainer cover). When you started the engine in your
slip the seaweed would have become stuck on the outside due to the
engine suction but would have dropped off after you stopped. If you
suspect that there might be more, you could either hop over the side
and take a look, or back flush the through hull with a fresh water
hose.

Bob should install water temp and oil pressure gauges. Also an audible
idiot alarm and maybe an idiot light. He could use the same audible
idiot alarm for both water and oil.

replace impeller

I can remember this happening to the diesel engine on the Mirage 33 I
crewed on.
Not sure if it was a plastic bag.. or seaweed, but it sure did scare
us for a bit.
