1985 Sea Ray Mid Cabin

I’m looking for a solves issue I had last year. I need to do it again and I’m not sure how I did it?
The plugs are not firing but if I connect a wire to the coil to a wire on the solenoid it runs. Do it once & it cranks & runs.

What boat you are driving is meaningless. What's the power unit? No reason to even post boat model when working on the motor.

I found my old previous post. Starting it for the 1 st time this season with a water hose. No spark while turning over fast.
It is a170 Mercruiser. I had the same problem last year. Once cranked I could repeatedly crank/run her again with no problem.
So today I connected a spark light between the # 1 plug & wire. No spark, no firing. Engine just spins.
I repeated what I did last year with no spark. That is I ran a wire from the + coil to the orange striped wire at the starter solenoid. Nothing. Then ran it to the + battery. No fire.
I saw a spark each time I touched them to the prospective terminals.

Try filing the points or just replace them. Ignition points build up some corrosion from long storage. If you do buy a set be sure to buy them from NAPA. Set the gap .016-.017.Stay away from those “big box” auto stores.
If you decide to convert to electronic here are the Prestolite kit numbers.
Sierra marine # 18-5285 or 18-5297 Either one will fit. Easy to install just follow the directions. They are not affected by moisture or long storage.
