Boat won't start - need help
I have an old 1976-1977 Ford 460 7.5 Liter V8 engine that I'm having
problems with. It is installed in an old 1977 jet boat (engine attached to a Berkeley J12E Jet drive.. I was out on the lake having a good time cruising around, pulled into a cove and shut down the engine to swim and when I went to start it back up it wouldn't. The engine wouldn't turn over. It was acting like the battery wasn't charging up via the alternator. We towed the boat to shore and trailered it home. I tested the battery with a voltmeter and it tested at 12volts and took it to a local auto parts store for a test and it came out fully charged with about 850 amps. I put the batter back in the boat and tried to start it up, but it still wouldn't even crank over. I pulled the starter motor out and had it rebuilt and put a new solenoid in as well. I've checked all the wiring, put on new battery cables and even a new starter switch all with the same results. It's like I'm not getting enough juice to the starter motor, it only cranks over between 1 - 5 degrees - certainly not enough to get it to crank over. Anyone experienced this before and could give me a few clues. Thank you, Layne Meier Atlanta, GA |

If that's the problem you need to get it serviced right away before it totally rusts up. I pulled all of the spark plugs out and the starter motor was able to spin. Once I added the spark plugs back in with compression, it was back to being unable to crank. Layne |

Can I suggest that you install the battery into a car/truck and see if it
turns over that engine. It could be a faulty cell in the battery. Do the battery cables get warm when you try to crank the engine? If the engine was working well before you stopped it I would not think it was water in the engine. Dave "Wayne.B" wrote in message ...

If you have water leakage in the wet exhaust system (manifolds, risers, elbows, etc.) or cylinder head area, combustion pressure will frequently keep the water out until you shut down. |

sounds like ignition timing is squew wiff,pre ignition will stop the
cylinders stone dead,..take the ht leads of and see if it turns over,if it dose,which i think it might,its time to look at the distributor......KB. LET US KNOW THE OUTCOME, TY wrote in message ... Kill switch, maybe? On 9 Sep 2004 05:28:48 -0700, (Layne Meier) wrote: I have an old 1976-1977 Ford 460 7.5 Liter V8 engine that I'm having problems with.

I don't think so..
It'd stop it.. but not dead. I've had timing 180 degrees off; and it'd turn it over quick at first, then stop it; then it'd turn again. He's getting very little turn and then STOP. Fuel has to be delivered in order for timing to be an issue; and the 1st second; no fuel is present....
