    Volvo Penta 5.7 gi-f won't run

    Sure wish some of the VP guys would come in. I'm offering Merc stuff to give you something but may not be what you have. My guess is since Merc doesn't appear to use the cam sensor, it uses the crank sensor. Here in the Merc manual item e (module) says not used.

    7.4 running hot?

    My nickels worth, you have a 1990 model 454 which (unless it's been changed) has an engine mounted fuel pump. If this is the case your fuel pump is dumping fuel in your motor and gas is mixing. This is why your oil level is going up and there is no milk. As for the your compression numbers...

    Formula 233

    So neither motor will crank over now using the key, but they will crank over using the PO switch on the motor, correct? In the pic below look for item 8, this is the slave solenoid. There are 4 wires on it, two large and two smaller. Put a meter on the small Yellow/Red wire and then turn the...

    Your on the far end of the B3 props with 26 pitch but should not be an issue so long as you don't over rev. B3 props run from 19 to 30 pitch for the 3x3 blades. You should have the 1:50 ratio for a boat that light.

    5.7 Gsi not starting, no fuel pump startup?

    I'm using the same drawing your using. In my first post I did say ECM turns on relays when I should have said relay, just the Fuel pump is turned on by by applying a ground to pin 85. There should be 12V on pins 86 and 30. When the ground is applied to pin 87 the relay should energize and...

    5.7 Gsi not starting, no fuel pump startup?

    Howdy and :welcome: Your looking in the right area and so far as the three on the 4.3 and less on the 5,7 I don't see but no worries. You need a good manual and the OEM is the way to go. The relays are turned on by the ECM by the ECM applying a ground to the relay, same happens to the...

    Agree with your mechanic, if it will not stay in the water, there is no need for the Mercathode So far as the fill of the tank, I leave mine where ever it is when winterized. In most cases I leave it with only a 1/4 tank. Never had boat gas go bad over the winter and I don't use stabilizer...

    Yes simple, get a 2x4 to put between the cavitation plate and the prop. Need a 1 7/16 inch socket and just remove the nut, then the rear prop. The next nut is 2 3/4, kind of big. There is a socket made by Merc and others and quite pricey. So you can use a large adjustable wrench, monkey...

    HELP: how do I take off steering/throttle/shifting cables from 40hp mariner outboard

    Kind of thought this would be easy for the outboard guys, but guess they missed it. I'll take a stab at it, and maybe they will come in to fill in what I leave out or say incorrectly. It appears to me to you just disconnect the cable from the link on the right, then loosen the nut on the left...
