This is a post discribing how I winterize a typical boat out of the water.(Inboard engine)
1) Remove 2 drain plugs, 1 in each side of block. ALL engines have them. Sometimes there is a hose going between them, remove 1 end and it will drain both sides.
2) Remove drain plug in back,bottom of each exhaust manifold. ALL engines have them. Sometimes a hose my be in that position, remove that end of hose.
3) Remove large hose end attached to thermostat housing.
4) Remove intake hose end from through hull.
5) Start engine and rev 3 times. Shut off engine.
6) Reinstall all plugs, and hose EXCEPT large hose at thermostat housing.
7) Pour 2 gallon blue -100 antifreeze directly into large hose and reinstall hose end.
8) Have 10 oz's of Rislone engine oil additive ready for this step. Start engine and pour 2 gallons blue -100 antifreeze through intake hose or into sea strainer(with vale shut off).
9) As you run out of antifreeze throttle up and pour the fogging oil dirrectly into intake carb. or plenum. and shut off engine. You are done.
OUTDRIVE engine
1) Follow steps 1 through 3.
2) Remove 2 smaller hoses from thermostat housing that lead to each manifold.
3) Remove intake hose from thermostat housing.
4) Start and rev engine 3 times, shut off.
5) Reinstall all plugs or hose ends down low that were removed for draining.
6) Pour 2 gallon -100 blue antifreeze into large hose going to recirc. pump.
7) Pour 1 gallon into each of the smaller hoses leading to the bottom of the manifolds.(you will hear it run out the back).
8) Pour the remaining gallon through the intake hose. This will go down slowly as the antifreeze pushes the water out of the system backward through the water pump and out the outdrive.
9) Reinstall all hoses
10) Start engine and fog as discribed above.
This will work for ALL engines made by GM. Do not use this on a Ford engine.
