Default Can this mpi be used with a Alpha drive

i haven’t seen this style of mpi engine before. I’m guessing it is an early one but I believe the gen+ had the vortec heads. I’m thinking 1997 or so, not sure.
. Anyway, I am wondering if it will work on a Alpha drive. (Shift interrupt) anyone have any info? How about the horsepower?

I can tell you I will NEVER own an mpi. I would put a fast or similar set up on a carb engine before I used any mpi ive seen. I've worked on multiple and they do not impress and seem like they always have a failure over something silly like a ground, pressure sensor, temp sensor. All stupid stuff that a carburetor doesnt care about. Stick with a carb and Tb

Pretty sure every year the Alpha's where available,all smallblocks where offered with them.

They call that a 350 Mag MPI, and from what I found on BAM’s site it was from 95-96’ and only came with bravo’s

Only if the ECM is reprogramed so the interruptor will cause the motor to stumble

How long it will work with an Alpha depends on how much the boat weights and how easy you are on the throttle

BTW: Give us all the info is given on the ECU/Relay box cover. That should give us a bunch to go from.

Default mpi

Here is the info on the tag . My boat is a 1986. Would that have a 8 pin or 9 pin connector on the engine.

Engine Serial # shows it is350 MAG. BRAVO MPI(GEN+) GM 350 V-8 1996 - 0F602000 THRU 0K001500

https://www.mercruiserparts.com/350-...350-v-8-1996-1
therefore, it is a 1996 and a Vortec headed motor plus obviously came with a Bravo outdrive.

Thanks. If I were to put that in front of a alpha any idea on hooking up the shift interupt? Could it be as easy as tapping into the coil power?
