well, i was asked to help a guy out and this is the situation: he has a boat on a lift on the water, he has no trailer. the water level has gone down too low to launch the boat so it is pretty much stuck on the lift until the water comes back up next spring. someone from a local dealer has come out every year and winterized it for him in this situation without any issues. he was referred to me by a friend so i went to take a look. i was only vaguely familiar with the system so i pulled out all of the blue plugs and drained all the raw water i could then re installed the plugs. i also disconnected the intake hose and poured A/F back thru the out drive until we could see it run out (it didn't take much). THEN i tried to pressurize the system with that little pump but it didn't seem to work very well. i also completely removed the hose at the back of the oil cooler, no water was present there. it is a cuddy cabin boat with a small head, vacuflush toilet and cockpit sink so i addressed all those items too. just wondering if what i've done will be sufficient as far as draining the raw water side of the cooling system since there isn't really a feasible way to draw A/F thru the system (that i could figure out at least). he said the servicing dealer did not run the engine when they winterized it so i talked to him about fogging the engine and fuel treatment. my only concern is the raw water side of the cooling at this point. i think i got it drained good, just wondering if anyone can confirm from the info i'm posting?? i would much rather put the boat on a trailer but it just isn't an option.
