My boat has an I/O but I keep a spare water pump impeller in my "OH CRAP " kit. I keep a plastic milk crate full of spare parts, motor and lower unit oil, antifreeze, first aid kit, assorted sections of hoses and clamps, long pieces of light and heavy gauge wire and wire lugs, electrical and duct tape, zip ties, 5 minute epoxy, tube of gasket sealer, small bag of assorted bolts, nuts, washers and screws and some special wrenches. Ive got a Cresent wrench set with over 100 pieces I keep in my truck and transfer to the boat when I take it out. Its hard to be prepared for everything but most problems can be taken care of with a good tool set and some ingenuity.
