Hey Guys,
This is my first post and I have gained alot of info from just reading a few of the posts on here so I am confident I will get the answer I need.

I got a 1976 Wellcraft from a "mobile mechanic" said the boat needed a starter solenoid...
After verifying it wasn't locked up I proceeded from there.

Here is what was wrong: The postive cable coming from the solenoid was on the starter post ALong with the negative terminal from the battery. The Coil was extremely hot so this is what I replaced:

Starter, ignition coil,points&condensor as well as the solenoid and ignition switch(it was sticky turning)


I wired it up according to an old shop manual from my old ford truck and it will fire off but as soon as I take the key out of the start position it dies. Essentially it will only run in the start position.
I have checked every wire as well as tried to jump the positive side of the coil with a wire from the pos side of the battery,same issue.

There is a wire going to the choke looks like a bleached tan wire or maybe white that was wire nutted together and prior to re-starting I disconnected it since it looked suspect. Same thing happened,it would fire off but die when in the run postition. If i connect that wire back together the starter will not disengage.

Can anybody point me in a direction to get this ol girl going?

Get a copy of the Merc manual and follow the ignition schematics. The starter solenoid should have a start post and a "run" post which will provide the correct voltage needed. I would imagine you have something running to the coil/distributor that is isn't getting voltage like it is supposed to from the "run" side of the solenoid.

Thanks for the input. I'll be elbow deep in it tonight
