    77 Carver 2866 Santa Cruz wiring help

    Being that old it's not likely you can find the diagram unless Carver has it. Most likely you would just wire using the boating industry standards. Don't know if you have a Gen, but without one of those run house Bat wiring, into cabin and use buss bars then go to fuse/breaker panels

    ECM Swap ? Plug and play ???

    From my looking around its my "opinion" this will do nothing to give you more power, or maybe noticeable power. Your original ECM 3885461 is NLA and not finding the replacement just looking at your motor In other discussions finding 3885461, 3885465 is replaced by 3889007 When a boat...

    Volvo 5.0 gxi Stalls at idle. Hard start.

    The Gxi-D shows 2 vacuum hoses 1 goes the the fuel rail damper, small hose The other I think would go to the valve cover PVC. If either are leaking it can cause issues with idle

    Fuel Injector Question

    Should have the injectors flow tested from idle to at least 5000 rpm. If they do not balance then need to be replaced if cleaning doesn't fix. If the O ring was not sealing very well there would be a vacuum leak which would impact idle and performance.
