240 SJ ECM issue

[NoBrakes!]

Buddy took his 240 SJ to Gibbons, they say the ECM is pooched and the old and new part numbers from Mercury are discontinued...

What to do?

Stand alone ECM of some kind? Used ECM from anywhere? I think this will be a common issue going forward.....

any help appreciated.

Should be lots of used ones. Facebook has a sport jet site lots off good guys with used parts on it.

Awesome, thanks!

I'm looking for a 824003A31 or 824003T31 if anyone sees anything pop up.

So I have been looking for a while and found none for sale really....

What does a guy do? I'm thinking this is not going to be an easy fix...

Any ideas for a stand alone ignition box? I think the Merc V6 fire multiple holes at the same time? hmmm....

or does a guy get ready to start retro fitting a V8 or something into these boats more and more as SJ parts availability dies off?

Looks like a lot of work to get a 309 intake in there....

Not sure how much you can trust Ebay, but here's one:

Sea Doo Mercury 240 EFI ECU PCM engine control computer ECM EMM 824003A31 | eBay

This is from a perfect running boat. If this does not work for you, you either need a different part or don't have the right model. This part is very difficult to find in tested and working condition.

Something like this is probably the route? How long does that used one last a guy even if its good?

I was going to suggest microsquirt but that looks better.

Ya i thought microsquirt too... This boat is at Gibbons and they're stumped... only option is to try a different ECU... Buddy has to do somethin'

I had sent a pcm from a Polaris atv to get repaired a while back. There must be a shop that could repair it.
