    Which Motor To Use

    if you want fuel economy, get a much newer motor..... like a newer 4-stroke. other than the ignition your 135hp and 140hp motors are essentially the same. both thirsty in-line 6-banger outboards

    A test port fitting and a mechanical fuel pressure gauge. If you are reading 7-8 psi, it will open the needle and seat and flood your carb However after cranking, if your fuel pressure drops, its either electrical or you may have a restriction in the line or your new pump may not be good

    FWIW, a 7" Garmin with down view / side scan can be had in the $600 range I know its readable at well over 50mph, and the side scan is good to about 20mph if you wait a month, the unit you were looking at will be reduced again as new units come out.

    1996 Volvo Penta 7.4 will not stay running

    go back to basics what is your compression? what is your fuel pressure? running for a minute and stopping is lack of fuel. i would look at the fuel pressure to confirm. Volvo's get their non-cranking fuel pump voltage from the alternator.
