Ignition Module Replacement for Mercruiser Volvo Penta OMC 4-cyl. V6 V8 Gm 10482830 16139399 D1965a Mercury Marine 811637 811637t 850487 18-5107-1

Works great

1996 Mercruiser 3.0 would start with some effort, run, and then die 10-30 minutes later. Once it was dead, it was impossible to restart until hours later.After replacing this part, it starts more easily and no longer dies. It only takes 5 minutes to replace!

1999 mercruiser 3.0 didn’t had spark coming out of the ignition cap/rotor, my instinct told me the module inside was bad even know it did have 12v with the key switch in the on position, installed this one and bingo, spark was back. Bought it in February 2022, and is only March 2022 but thus far so good.

Works and attaches just like oem but much cheaper

Replaced brand new Mercruiser module that lasted 5 hours. 20+ hours on this and no problems. Great price.

Only 1 out of 4 items arrived

I dislike this product because it was Defective right out of the Box. Left me and my girlfriend stranded in the middle of the lake. Good thing I kept the old one!

I purchased this for a 1996 Bayliner Capri with a Mercruiser 3.0L engine. Long story short...I swapped out just about everything on this engine and got it to run but when I took her on the lake and after turning off my engine I wasn't able to restart it. I was stranded for 45 mins before it fired up again. Luckily I made it back to the dock that day.Bought this in hopes it would fix the problem and so far it has! It now starts up with no problem and fires up every time. Bought me a second just in case. Hope that helps someone.

When in base timing mode there is a no start condition for a mercruiser 3.0. Will return. Item also looked used when received. Replaced with a Napa one and worked flawlessly.
