Thank you Bruce and Scotch,
Today i swapped out the ecu engine started fine
Put the bad one on the other egine it started also but smell gas
I concluded that cylinder one gas valve stucked open due to bad ecu. Will send it out for repair.
By the way i found water on both of mine boxes
Thanks again for your time.

Glad that you've figured it out. Seems like it's been a common issue with your vintage of boats. Good luck with the repair. Also, make sure to check the oil on the affected engine to make sure it's not contaminated with gas. Either way, it's a good idea to change the oil out just in case.

One theory a member had was that water washes over the swim deck and goes up the back of the engine compartment and sometimes (not often) makes it over the back and onto the top of the ECU. So one idea was to tape the tops of the ECUs to keep them drier....
