When I try to start my 115 Hp Mercury inline six cylinder (mid 1980's) motor when it is cold the bendix will usually drop out of the flywheel after a few revolutions of the flywheel. I have to keep turning the engine over until the bendix finally stays engaged long enough to start the engine. I have replaced the starter and bendix, solenoid, and battery cables. The flywheel gearing looks fine. The battery is a new 1000 CCA one and was recently tested at 975 CCA. When the bendix drops out of the flywheel the voltage at the starter is between 11 -12 volts DC. <br /><br />Update<br />If I remove all the plug wires the bendix will turn the motor over as long as the key is turned. Do I need new plug wires? a coil? ??

Sounds like engine is kicking back (reversing rotation on cranking. Could be ignition timing problem or other ignition problems. A tune up and timing check would be where I would start first.

Nope... It's "sneezing" ie It's *trying* to start for a moment and the fast *forward* revolution kicks the bendix out.<br /><br />Nothing is "broken".<br /><br />What you need to do is almost flood the thing before trying to start it. Make sure it's trimmed all the way in too. Assuming it's set up OK, then it's the starting procedure that needs work too.<br /><br />Make sure the choke is engaged while cranking and the throttle is advanced a bit.<br /><br />Cold starting the big inlines is a talent, it helps to run them every other day to keep them "wet" if yours lives in the water.<br /><br />-W
