Thunderbolt V Ignition Module

[Pontiac1983]

Anyone have a replacement thunderbolt 5 ignition control module for a mercruiser 5.7? I ordered a new EST ignition but looking to get back on the water while waiting for shipping.

Lakeport Landing has them in stock last time I needed one. Give them a call.

Thanks billy. Just called M&M and it appears he is closing. Actually pretty funny voicemail when you call because he does have some parts and if you leave a message, he will call you back after he gets off the golf course.

Those stupid things have caused me so much grief over the years I had actually considered keeping an extra at home,,,

Lost a motor one year when the module dies half way through winterizing and thought it was good enough. Sure enough it was a brutally cold winter and at next start up in the spring I had water in the oil and a junk motor.

Good luck!

Got a replacement ignition system. Went with the Delco Voyager EST system. It’s still an electronic timing system but eliminates an external computer. Replaces the wires, coil, plugs, and distributor. Fired right up after I got it installed.
