Is there anything wrong with starting your boat on the driveway and letting the water just shoot out instead of draining the block? Will that also blow all water out of the heater? I am talking about just starting it for a few seconds. I am also not talking about a complete winterization, but just to drain the block for a few days if it is going to be cold. Will it affect the impeller? Anything else? Thanks for your advise in advance... just looking for an easier way and can't figure out the negatives....
