    1995 promax 225 efi ecu problem.

    Just got my motor back from a complete rebuild. Still in break in. Mechanic loaned me an ecu while I sent mine off. The motor has started first crank every time and ran great until I put my ecu back on it Im probably going to send the e u back but my question is will an ecu of the same type from a 150 work on my 225?

    Try Dennis Hoffman @ Hoffman Marine, he's the real deal. I recently had my 2.5 rebuilt / overhauled last fall and had to do like you and send my ECU off. Had to have it reprogrammed and rev-limiter set. Sent to a very reputable company 3 different times and they never got it right. Sent it to Dennis and it is perfect. Ph.# (901) 277-2151. Give him a call, he's a straight shooter and up front guy.

    Do you know what "program" he used on your ecu?

    I changed plugs and there was no change in the engine.
