Built Ignition Interrupt Circuit

[chopperdog]

I have had recurring difficulty with shifting with a 1988 Bayliner Ciera, OMC 4 cylinder. I know this is a fairly common problem. In and out of the shops (more than 1), working on it myself, all the frustration!

Mechanically, the outdrive and engine are great. The problem has always been with the ignition interrupt (ESA). I replaced it, and the problem still persisted.

I know, if everything is adjusted perfect, it will work. But really, it never did for me. The problem is, if the ESA doesn't work just right, the extra force on the cables to shift eventually gets everything out of alignment, leading to more shifting problems. Or worse, it could cause gear damage, which I have luckily avoided.

So, I got fed up, and designed an electrical circuit to do what the ESA is supposed to.

It works like a champ! When engaged, the RPM pulses from about 600 to 200 or 250, then resumes 600 at idle when I am done shifting. Just awesome! Way better than the 2 previous ESA's I purchased and installed.

Now I like my boat again!

Just sharing my enthusiasm.

So lets see some pic of this wonderful new device.
There could be a patent in it for you.

Congrats on the success.

Thanks.
I didn't take pictures of the circuit before I encased it a water-tight enclosure.

I will try to take a short video of it working tomorrow and post it.

Basically, when the switch is activated, which can be done when pressing
the neutral lock release, the ciruit activates, reducing the rpm in pulses.
Easy to use, and very effective.

A bit more difficult to actually design the circuit than it would seem, but it was worth the effort.
