Drain Plugs

[Fly100]

Im sat her in my warm offfice here in the UK and well its getting to be that time of year.

As a new Ski Nautique owner (1996 196) Im reading about drain water and adding anti freeze.
My quest is ( and I have had a look through using the search box) How many drain plugs are there and where are they.

Ive done some work on my boat over this summer and I cant say ive seen any !!

All advice grealty recieved as ever.

RE: Drain Plugs

One each on the ends of your exhaust manifolds. One each on the side of your block, under heads. one on the bottom of your RWP tube. If you have a heater, you need to remove the two hoses off the block for that, and blow out the water in your heater.

And another one at the bottom of the 'U' bend beside the engine water pump. BTW, if your boat is running LPG, the drain on the port side is likely to have been replaced by a hose that feeds hot water to the gas vapouriser.

Is there a knock sensor on that engine? If so, does it need to be removed?

On a lot of the GM engines, the knock sensor is one of the block plugs. When it is reinstalled, it must electrically ground to the block, do not use sealer on it.

My 502's port plug is just a plug, knock sensor is separate. Must just be on the little ones. ; ^)
