Default Convert an '87 Mercruiser 3.0L to electronic ignition?

I would like to convert my '87 Mercruiser 3.0L from points ignition to electronic ignition.

What parts do I need to do this conversion? Is there a kit made for doing this conversion?

Thanks,
Michael

There are a couple of conversion kits available for the Delco point ignition. Not sure who makes them offhand but pm me and I'll get back to you tomorrow. Personally I'd stick with the points though. Replace points condenser and cap every spring and you shouldn't have problems.

No idea about '87, but Merc apparently used either Ford or GM 3.0's at times.

Pertronix doesn't seem to list anything specifically for Mercury 188 in their marine conversion kit section of the catalog: ( Pfd p 18 )
http://www.pertronix.com/catalogs/pd...tronix2010.pdf

If yours by any chance has a Mallory YM or HP advance distributor, Mallory Performance lists 2 different 4 cyl marine conversion modules for 2 diff. cap styles , "high-stack and "mini-bowl":
http://www.malloryperformance.com/Pr...minselection=4 (bottom two.)

Hopefully sjef can fix you up with one of the marine electronic replacement distributor kits with elect. distributor & matching coil & wires, which would likely be the best but pricier way to go on an engine with a 23 yr old distributor & advance.
FWIW- MichiganMotorz has the really good Delco Voyager EST Electronic Distributor kit #107A for a 3.O L engine (GM) for around $200.
I used the Delco Voyager EST kits on my old 5.7L engines and they were terrific. Wished I ( actually the yard) had put them on years ealier. I think they were the ony marine replacement electronic distributors that had electronic advance, not mechanical .

I am pretty sure that the distributor is a Delco. The motor is a Mercruiser 130hp 3.0L.

Does anyone know if this Pertronix kit would work work?
Year - All | Model - 110, 120, 140, 165, 170, 180, 190 | Footnotes - 79 - Does not work with solid core ignition wires | Dist No. - Null | Dist Make - Delco | Ignitor - 1146A | Ignitor II - 91146A

Would I be better off buying something like the Delco Voyager EST Electronic Distributor kit #107A from MichiganMotorz?

I hope sjef gets back to me and lets me know what he has to offer.

Thanks,
Michael

I did it and never looked back, though I can't recall the source. Good luck!

One of the best upgrades you can do. Hotter spark and no more points to mess with.

About 15 years back I converted a 5.7L volvo penta to electronic ignition. I just bought a used distributor, and with trade-in got it for about $75.

Not sure how much the kit is, but it was the best $75 I ever spent on that boat.
