Winterising Mercruiser 4.3L

[jak2108]

Hi,

I want to winterise my mercruiser 4.3L 1990 model. I have taken out 1 drain plug on the exhaust elbows on each side and 1 on each side of the block at low level. I want to know if there are any more to take out. For some reason I thgought I read somewhere that there are 2 on each side of the block but i can only find 1.

Thanks

Ayuh,... It's 2 on each side of the Motor,... 1 on the Block,+ 1 on the Manifold...

If you have P/Steering,.. Find the Cooler,+ pop 1 of the Big hoses off to drain it...
Also,..
Pop the Big Hose off the circulating Waterpump,...
It's hiding about another Quart or so,... Enough to do Damage...

Whats funny is I have 1 OMC that I work on that's a 4.3 that only has 1 plug on the port side.
