    water shut off for towing

    I know plastic is lighter but,, this was free, It's a 3/4 inch. Is that big enough to not disrupt the water flow in? The inlet hose is 3/4" correct?(on the Pro and the SLX).

    That is plenty of flow diameter.

    Be sure to mount that heavy assembly so it doesn't flex or bang around when bouncing across the waves

    3/4 inch is the hose size.

    What some have done is combined the valve (plastic valve typically) and the water strainer. The strainer keeps lake junk out of the engine water jackets, and is especially useful for keeping clogs away from the small orifices that inject cooling water into the exhaust.

    yep it will do the job. id strip out the lever valve, connect coper pipe each side with compresson fittings, and cut and push onto hoses and clip, id try to strap it to something to stop from rattling about,

    . it is heavy. But the valve moves smoothly. Might be a tad lighter if I get those anchors off the ends!.

    I just think its absolutely mandatory to do this upgrade for towing. Towing is a real possiblity and to ruin an engine over something so simple is just dumb.

    Dude that valve is kinda ugly to put in a ski. What I made was just a 1/4" thick piece of Aluminium with a slot cut in it and filed up nice and smooth. Then when you want to bock of the water for towing or back flushing etc just slide it onto the hose and clamp it off like a brake hose clamp. I then put it on the flushing adapter with a piece of stainless steel wire rope and keep it in the glove box so that I know it doesn't get left on by mistake and overheat the engine.

    Clamping the small exhaust water injection hose will prevent engine flooding through the exhaust. Which is where the risk of engine damage comes from.

    Clamping the big main water feed hose will also protect against hull flooding from leaks from anywhere in the cooling system.
