I just purchased a boat last Year. So i dont know much about them. I asked 2 guys with boats how they winterize their boats and they said to just put fuel stabilizer in the gas tank so it doesnt collect moisture. Well i did that. Now people are saying that i should of put anti-freeze in the motor so the water doesnt freeze and crack the block. Well knowing my luck the block is going to be cracked when i get it ready once the weather gets better. I wish i would of known about it because it would of saved me a ton of money. Does anyone have any tips before i turn the motor over? If the block is cracked, what do they cost? Its a 60 horse Mariner. Im heartbroken. Any advice would be great. Thanks.
