2460 Denali

[dorado1045]

:flag: I have a 2001 2460 Denali with 5.7 l Mercruiser and Bravo III outdrive. I has not been used much the last 2 years and attempted to use this year. On the first trip out ran fine all day except for the last hour. The engine died , visual inspection showed the water pump pulley not turning. Got towed in. After trailering the boat home proceeded to remove the water pump(both), the exhaust manifolds and risers. Observed some rust that may be clogging the water path thru the manifold. Replaced both manifolds, risers, water pumps, and thermostat housing and thermostat. Attempted to start boat in the driveway, would not consistently turn over. After a day or 2 of playing with it, removed the port manifold and looked at the starter. There was a broken standoff for the low voltage connection on the starter, replaced starter. Boat turns over consistently now. However, it will not consistently run, sometimes it runs and sometimes it will not. One thing for sure, if I drop it in the water it will not start, all the time. I need some suggestions as to what may be wrong. I am thinking about changing the fuel pump and the fuel pressure switch. Any ideas!!!!!! :worthy: :bang:
