Looking at an 02 bf130 for my boat. I don't have the serial number but I'm pretty sure it's one of the recalled ones with the head issue. Guy says it started overheating and then had water in the oil. He only wants 400 for it w controls and stainless prop. It's very clean and in good shape so I can't imagine it's not worth that kind of money. Is it? I will be doing the repair myself and I'm wondering if anyone can provide some insight on how their repair went and if I will need any additional parts. So far I have found a bare head for 477, gasket for 95, thermostat for 20. Am I wasting my time/money?
