    Help finding drain plug

    The service manual for my 350 MAG says there is a coolant (water) drain plug on the hydraulic steering cooler, but I can't find it. Any hints?

    Yes, that sounds like it, thanks. I will do that. It seemed to me that the fuel cooler drain would get most if not all of the water out of the steering cooler. This is the first time winterizing on my own, and I want to be sure I get it right. I have winterized Sea Doos and outboards, but not an inboard.

    All power steering applications have a cooler, many are at the rear but some are tucked in next to the engine down low on the port side just ahead of the oil filter adapter like mine. Follow the intake hose you will find it it.

    Right. The engine block, manifolds, and fuel cooler all had blue plastic plugs. Don't think the steering cooler has one. I can't see under it, but going by feel I can't find one.

    I was thinking about running antifreeze but I already put oil in the cylinders and I don't want to do that again. It shouldn't be necessary if I do this right. I had a couple boats at a marina for years, and they always just drained everything. I thought about just running antifreeze only, no draining, but from what I read the antifreeze might not get in all the internal passages and you need to insure that the thermostat opens or remove it i suppose. I guess this is a choice like fuel tank layup - full or empty or otherwise. Different ways to do it, each of which has pros and cons but probably works.

    That's quite a setup you have.

    My 454 has a blue petcock drain on the fuel cooler where Mop suggested, but I never remove it. It is easier and faster to remove the hose.
