Winterizing the Boat
 

I'm thinking of an alternate method of winterizing the engine. I have
to remove my risers for maintenance (boiling out the rust).
What I was thinking of is instead of filling the block with
Antifreeze, I thought I'd take off the large waterpump hose (looks
like a car rad hose) , and hook my Shop Vac up in REVERSE and blow all
the water out the drain cocks instead. Sound like a good idea?
My block seems to have a pocket that traps water inside on the
Starboard side.
Anyone else ever done anything like this?
