Running good, rough water, hit a wave.....

[Saginaw Bay]

Bam! no spark. fuel check!, Air check! spark? not really.

By not really, I mean boat fires when WOT in neutral, but just for a second.

Coil is now leaking oil.

A new coil is in order ( can I get a coil from Autozone?)


But I think the shift/throttle is the culpit here.

In reading some things here, I realized I was stalling when returning to neutral. I would give throttle in neutral, then ease it back to engage forward or reverse.

I am thinking something there got jarred, and now now allowing the shift inturrupt to function properly.

I didnt dig into it much, was on the bay with good 4 footers rolling.

Now at home, is there a way to disable the switch? I imagine disconnect a lead to the switch, as "in " on the microswitch is engine off position.


how far off am I?

What kind of motor and drive is it we're talking about?

Re: Running good, rough water, hit a wave.....

Sorry, 888 (302 V8) and mercruiser 1 drive.

Not sure what the throttle would have to do with no spark. If the coil was going bad you were probably stalling because of a weak spark, nothing to do with the throttle.

Yes you can get a coil from Autozone, but I would look for an apoxy filled coil, not oil filled, better for vibration resistance. They may or may not carry one.

Needs to be USCG approved, and oil filled/epoxy filled both have negligible difference in vibration resistance.

It tries to start, 1 quick fire then nothing.

Do you have a resistor on the motor not sure what year you boat is but had a friend that had the same trouble when we we out. Found a burned resistor changed it out and all was good his was a older boat cannot remember the year but I think was in the mid eighties. It would start for a couple seconds and then shut off.

Looked through the manual didnt find a resistor.

1972 Slickcraft. mercruiser 888 and mercruiser1 drive.

I imagine the coil is shorting out due to the leaking of oil from it.

Will this condition still allow the engine to fire?

What reading should I be looking at the coil?

Nevermind, its leaking, it requires replacement.

Does it have a kill switch on it?

I just dewinterized my 2004 Stingray 200LX last week and I tried to start it. It would only light off for a half second. I pushed the throttle up and tried again. It would fire for only a half second. I played around with the throttle positions wondering why the engine would only fire for a quick half second !

Then I looked on the floor and saw my kill switch lanyard just laying there. Plugged it into the kill switch and she fired right up like normal :redface::redface: .

No kill switch on that 888 Slickcraft, Replace the coil and get back to us.

Re: Running good, rough water, hit a wave.....

Coil replaced, Same condition.

It will fire 1 quick time then nothing.

Whats next?


Condenser?

Re: Running good, rough water, hit a wave.....

Are you useing a factory manual? Might want to check your ignition switch also do you have a piece by the coil that looks like it is made of ceramic?
Just reread what you wrote did you give the motor a tune up since having the problem if not could be part of the trouble....
