ALPHA 1 strength?

the merc tech is right, the ecm will have to be changed to allow the shift interrupt to work with the alpha( i tried this a coupe of years ago), I'm not sure about straight wiring in a shift intrerupt to the coil, it may damage the coil driver, I thought about interupting the IAC but it would throw codes everytime it activated. That throtttle body motor is more than enough for that V. Keep the MPI/Bravo for the next project

It aint goin in a V-20, it's goin in a 250 SEARAY CC. The late model shift interupt switch works by breaking the circuit for the coil driver, vs the old style that grounds it. But I was told that if I interupted the signal the ECM would throw a code and go into safe mode everytime I took it out of gear.

Slightly larger(and heavier) than a V-20

My big hurdle with the bigger engine is the ECM and the shift interupt switch. The ECM on my 315HP is actuaully programmed for an inboard and a shift interupt will drive it nuts. My 260 TBI motor is already wired for the interupt and a direct match for the ALPHA1's origanal engine's output. I just want this thing gone and done, I want to get me a 26' BERTRAM or a WELLCRAFT 248(but that's just me).

if I were going to keep it, I'd put the 5.7 MPI/Bravo set up in the Sea Ray, see if you can trade around and end up with a Bravo III lower, it makes a big difference in boats like that 250( i worked at a Sea Ray dealer for 6 years, I 've seen the difference in take off and cruise performance)

That's the thing, I don't want it. I don't like the layout of it at all, it's not me. My buddy wants it and knows I have this stuff but is trying to get me to give it to him for what I have in it. Problem is, I don't have much in my 315 and it's worth some money when I can prove it only has 64 origanal hours and a 2004 model. Even the guy at MARINE MAX said the previous owner babied it from looking at the RPM history. I would rather sell these parts seperately and put more cash in my pocket. I really hate how some friends try and milk ya.
