Install a Delco EST Ignition on a Mercruiser 

Legend! Greetings from Germany and keep up the good work mate! :-)

Great video. Just wondering how the boat performs on the water after the conversion. Better, worse or the same? Does the cutout switch function as good as before? Thanks

Been having a hard time getting my mercruser out of gear. Need to look at the possibility of the engine cut out not working. Thanks.

Hey just from looking at it it looks like you have the exact same set up as my 5.7 and I was curious what you used as a Keed 12 V connection for the cut off switch And which wire is the Interrupt wire on the distributor kit?

So what did you do with the yellow wire for the temp switch for the audio alarm that went to the old Module

Video is great! What's the part number of the kit you bought? I have 2 Bayliner capris and not getting spark . both of the modules are bad. Thanks!

Hello where did you purchase your delco est system from? I have a thunderbolt IV system currently.

What about the all in one hei distributors on ebay for 129 bucks. They have a coil on the unit.

Do you have a shop? Would like mine converted.

Man I just rebuilt my engine then on the water while running it just shut down. Then it wouldn’t start. I’m not getting any spark. I think my ignition module is bad.

Nice. Mounting the coil on the hull of the boat in a convenient location could be problematic. The screw could go through the hull and protrude out the other side where somebody could be injured by the screw protrusion?

Your video was useful as I needed to know more about the Delco distributor. I would like to add being as former automotive master tech. I would mount the coil on the block so the coil is grounded. Coils have always been mounted to the engine and never had an issue with vibration failure. At least run a ground wire to the coil if not mounted to the block. Just sayin. Anyhow, , I have a 7.4L MPI in my boat and under a current rebuild now and eliminating the MPI system with a carb with minor performance modification. Do you know what the timing curve is on the Delco EST and would this be suitable for a modified engine?

Did kit come with ignition cutout switch,

nice video, how to check what Thunderbolt ive got on my 4.3 ? take care ps. im waiting for more Carb video ;) !

Cant you just put a hei distributor in
