Volvo 5.0GL raw water cooled - Boat is slipped in salt water in the VA Chesapeake Bay area. I do not have a trailer and would like to stay in the water until late DEcember, but I can't winterize in the water because there is no shut-off valve in the intake hose. Next Tuesday night it is supposed to go down to 20 with a high of 32 the next day, then it warms up for the rest of the extended forecast. Would you go ahead and haul out for the winter or stay in to fish the rest of the striped bass season? Any thoughts appreciated.
