So during winterization the other night, I removed the raw water intake ate the seacock shutoff and placed it in antifreeze in a bucket per recommended, and started the motor, it didn't suck any antifreeze in. In the past I remember my mechanic telling me my boat doesn't use the rabbit ears, rather that for running on land using a water hose connection to it, when not in water but the boat also wound up with water in the cylinders after he was done, so I'm wondering if he was forcing water in and that's what caused it, but I also read that the raw water pump should suck in about 30 gpm, is anyone familiar with this? Does it suck water in the bottom of the outdrive as well as the seacock? I'm just getting to know this boat, last year my mechanic charged me over 800 for winterization, this year it's at my house. I poured antifreeze in there til it came out around the exhaust, none came from center of the prop, but when I took the hoses off the risers, there was antifreeze in those, as well as coming out of both drain plugs. Should this cover my motor block or anything else from freezing? I'm 100 percent confident my fresh water system and toilet, etc is good, any input would be appreciated.
