Hello all new guy here. Last week I purchased a 2004 Bennington RL 211 from a dealer. Went to the lake on Sunday and the engine alarm went off as soon as we unloaded it. Checked all fluids and started it back up. It ran fine for 10 min then the alarm went off again and motor shut off. Checked everything fluids, temp, volts, oil pressure good. Cranked it back up ran fine for 10 min then the alarms went off and it shut off again. Took it back to the dealer on Monday. Dealer calls and said a head was cracked and they fixed a few more things. The dealer is putting on a new set of heads at no cost to me and will loan me a boat for Memorial Day weekend. They are also offering to let me cancel the sale and walk away. The dealer I feel is treating me right and bending over backwards to make me happy. So long story what is your opinion, with a cracked head would you keep it or let it go back to the dealer. I don't know if there is any damage to the block or is this a common problem with 5.0 Mercruiser Stern drives? I have had one other boat and it was an outboard. So any advice would be appreciated.
