    How would you ever know for sure that water got to the engine cooling jackets or for that matter, came out of the jackets?

    The engine water jackets are all above the level of the X fitting (assuming hull is sitting level or bow high) and above the jet pump water screen inlet. So the engine water jackets gravity drain down and out towards the jet pump (the opposite direction of the jet pump water flow feed when hull is floating and engine running).

    ok...now I have this pictured. So obviously a complete waste of time to use antifreeze if someone were to be concerned about the block freezing.

    Shrink wrap is last step. I also wrap the trailer(s) hitch, etc., with contractor plastic bags and duct tape, some people use saran wrap. I wasn't brave enough this year to use MaryKay On/Off on the FX hull like I do on the fiberglass gelcoat boat hull - stuff is amazing for removing waterline lake scum (eats through steel - need to cover the trailer and yourself (acid)). I get two or three years out of the shink wrap

    I use the red label for the boat (apply with paint brush) but if you have success with this yellow label gel on my FX hull I'll try it. Thanks.

    I have not used either.

    Just clarifying that MaryKay was not the correct brand name.

    Do you have a problem with mold? Shrink wrap will trap moisture and can cause mold to form on the upholstery, etc.

    For years I never had an issue with mold. Not once. I never shrink wrap but rather store indoors.

    last year....mold on one machine and most the other. Don’t know why. Must have been wet/damp when I put the cover on it.

    i probably should have put some type of water desiccant under the seat this year. Maybe I still will if I can get to the machine still.
