Sorry for the delay. If you already have the plugs out, crank each engine till no more water can be seen coming out. Then fog the cylinders really well with a spray fogging oil or WD40. After that replace the plugs and try and get the engines started ASAP. Let them run for a while to get to operating temperature (use a hose on land ideally). I also like to fog them again after running before storage, just to get any remaining moisture out of the way.
