how do you "winterize an outboard?
 

OK, my brother just bought a boat this summer and had a lot of fun
with it.

now he's giong to store it away. It has a v-4 Evinrude 115 horse on
it.
He's heard from some that these engines are self draining and there's
no need for fushing anything though the water inlet to chase out the
water.

I really do find that hard to believe. but then again...I don't know.
I did however, recomend putting Stabilizer int he carbs so they don't
urn to shelac.

Is there a process for proper winterization on the 2 stroke v-4's?

THANKS!

Tim:

I can't speak for that particular engine, but here is some general advice:

To prevent gum forming in your carburetor, close the fuel valve and run the
engine until it dies from fuel starvation just before pulling out of the
water the last time of the season.

Most, maybe all, outboards are self draining if you leave them vertical for
a few minutes. One gotcha is the prop. With the O/B tilted up during the
winter, rain can collect in the prop hub, freeze and crack the hub. Store
the O/B with it tilted near vertical to prevent this.

Another thing to do is to remove all spark plugs and crank through the
engine while spraying WD40 in the plug hole. This will coat the cylinder
walls and prevent rust over the winter.

That is about it for winter storage.

Thansk Dave....

I ahdn't thought about leaving the engine in down position, but that
makes sense.


LOL! I wish my mercruiser was "self-draining". Winterizing is easy,
but kind of a pain.

Stabilize the gas, fog it, check or change the lower unit lube and run
it for just a couple seconds in a verticle position to spin the water
out of the pump.

i think the main idea is to make sure there is no
water anywhere in the motor, that may freeze and
expand....

I agree with most of what you've said, but I've left several different
outboards raised and tilted in freezing temps with no problem.

I have been told that the lower unit should always be left down in the water
to keep the (undrained) cooling water from freezing, however a top notch
mechanic said that was true only if there was water inside the lower unit
that had leaked past the seals...obviously a problem itself.
