Wards 15hp on 1 cyl, Ideas??

[jakeyman_i_am]

Hello everyone,
I have a 15 hp Montgomery Ward outboard.. Since buying it I have done a lot of work to it including a new water pump w/housing, new prop, plugs, and some replacement hardware to make the throttle work again.. Now I have a new problem and since this part of the motor isn't covered in the basic manual I have, I need some advice before buying anything/moving forward.

I was out on the lake one day and the motor was running great.. I shut it down for about 30 minutes and when I fired it back up, it was only running on one cylinder.. Since I had been doing a short troll with it earlier I though it could be spark plugs.. After replacing them/starting motor with the new plugs the issue remains.. If I am on the lake with it, it starts easy, but when you have it in forward it is obvious that it is only firing one plug.. Every once in a while the second plug will kick in, but never for longer than 3-5 seconds..

Any ideas what might cause this? I have tried 2 new sets of plugs, and they do not look fouled at all. My plug wires are in great shape w/o any cracking or major wear. Do I need to do some work under the flywheel?

Thank you!

Can't help without the model number, Jake.

No outboard that I know of was branded Montgomery Ward. I think you must have a Sea King, but that still leaves a problem.

Over the years, Sea King outboards were made by several different makers.

Need to know who made it and when.

Sorry, JB, I forgot to list the model number.

It is: VWB 52015 (74 Sea King)

Thank you!

I googled the model no. hope it helps you.(edit) and yeah I would guess you need to check your points and coils. I forgot to offer my advice and had gotten busy trying to identify your outboard.

It's a West Bend/Chrysler Sea King. Sounds like you have a bad coil that craps out after the motor warms up.

Thanks, I need a puller to get the Flywheel off right?

Yes. Not familiar with your motor, but if there are three threaded holes in the top of the flywheel you can use a harmonic balancer puller available at any auto parts store.

I ordered new points/condenser today because I got the Flywheel off and the points are corroded very badly.

I hope that is the only issue (not the coil) because the coil is $120 from Discount Marine Parts... Pretty soon I will have a brand new (not quite..) motor if I keep replacing everything..
