    If one were to store a jet boat in freezing temps, w/o an engine in it is there any risk of damage? Any place in the pump water could be trapped and freeze to cause trouble?

    Other than the normal water hoses and whatnot, not much damage could be done in the pump, if you are worried about it, lift the bow of the boat and drain the little bit of water it holds/traps. IMHO there is not enough water to do any damage. I have seen wood stringers that were water logged split open the fiberglass in extreme cold, but probably rare (Canada boat).

    flush the bowl cavity with fresh oil or grease. water can become trapped inside there.

    Just replaced a bowl for a customer that was cracked in this area because the bowl bearing cavity froze. Not visable until the bowl was removed.

    x4 on the water in the lube, also my .02 is pour a proper mix of anti in to the hose and back wash the bowl. did not think it was possible but have replaced 2 bowls bursted from the water frozen that remains in the lower half of the bowl. best situation remove the bowl and store it in a heated area. better safe than sorry.

    Thanks for the help guys. I like the idea of pulling the bowl off, eliminates the problem and just a few nuts. Any thing special to care for when removing said bowl?

    BTW boat will be stored outdoors covered as the engine is being used otherwise and need space for it's new home. Any one interested in a 77 Sanger Custom Sprint Jet, orange and yellow, set up for BBC of course. Ready to move it now. Will be in SoCal this weekend and could deliver and wouldn't have to pull pump(tomorrow night).

    Any one interested pm an offer.

    Maybe get a cheap suction gun from Napa and some tubing (to reduce the size) to draw the existing oil out (assuming its even milky or contaminated to begin with ) or force enough oil in one side to "flush it" out the opposite ? might be alot less work than bowl R&R re the SJ pm a "number" and more info if your so inclined

    I've always managed well with the "flush it out the other side".
