This happens with any battery I put in it. I even had a Snap-on starter boost charger on it and still not enough cranking. I ended up wiring 2 batteries in seires for 24volts and it would crank fast (but still not start), then kill the batteries after a few times. I am wondering if I have a dead short somewhere and if anyone has any ideas before I start replacing stuff. I just replaced the coil and after doing some tests per the Penta Book and now I have spark, but I am worried to put the 24volts back on and damage anything. I orginaly put the 24volts on from some advise and now I hear that can mess up your system. Help Please!! Ok...here is the latest. I took the starter off and took it to the auto store. They tested it 3 times in a computerized machine and it tested fine (passed) on all levels. Went *home and put the starter back on then double checked all the electrical and conections. Tried to start it, but same thing. Pulled all the plugs and wammmm...spins like crazy. My next step is to pull the valve covers and make sure all valves are moving. Any thoughts? YES! leave thevalve covers alone. why do you want to get radical with valve covers? why not pull the engine and take off the oil pan and see if the crankshaft is turning? Pardon me, I dont' want to come across like a smart -alec, but . look at the bigger picture, Are you sure the ignition timing is correct? too far advanced timing and the starter will act like it's hitting a brick wall because the cylinders are firing too soon. You said you replaced the coil. so I'm wowndering inf you did any thing else to the distributor, by chance? OK so you took the starter to the parts store and had them "test it" . like most part stores, they possibly will hook it to to a fancy- schmancy machine and let it free spin and scream at the top of it's lungs. did anyone ever think to take it apart and see what kind of shape it looked like inside? HECK NO! But it sure spun good. so test passed. |

Double checked connections? Or disconnected and cleaned them? Visual inspection will not reveal a bad connection. You must either disassemble and clean it with a wire brush or put a volt meter across it and measure the voltage drop when the starter is engaged. Taking it apart and cleaning it is easier. Trust me, on a 1987 boat you have wiring corrosion. It may or may not be your problem but you do have it. How long has it been since the boat ran normally? What exactly have you done to it since it ran normally? Any of that done before it became hard to start? Also the water question is valid. Did any water come out of the plug holes? Any of the plugs look like they may have been wet with water? Unsure? Put the plugs back in, leave the wires off, crank it. If the wires are off then it should crank normally. Timing issues will not affect it with the wires off. If it still does not crank normally then you still have starter issues. |

If one or more valves aren't moving, you'll have some damaged pushrods at least. If all of the valves are moving, you may have some serious valvetrain issues.... Does it even try to fire? IF you're getting firing or backfiring.... I'd look for ignition issues. Does it have a distributor? If so.... it might be a carbon track. -- Grady-White Gulfstream, out of Oak Island, NC.

And valve train issues are not likely to cause a starting problem either as they would most likely affect just one or two cylinders. It's not time to remove the valve covers, the symptoms don't suggest that. |
