    Awesome, that worked like a charm. I'm assuming I would just splice these connections together correct or do they make a female plug that jumps the connection?

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    If you can send me what connections need to be jumped since I detached the transmissions to list one of these 8.1s for sale and one for install that'd be great.

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    It did have a ZF 63 transmission attached. I think that might be my issue then! I started the other engine when the transmission was attached still... I can't believe I missed it. Do I need to change anything electrical since I'm converting it for a sternboard? I have the other engine I will be...

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    The only spot that I did not have 12.4/.5 Volts going to was the red/yellow connection at the slave relay and where the red/yellow wire leads to on the starter solenoid. Every other connection with the yellow/red wire had 12V to it and I checked the positive connections at the starter, slave...

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    It's a 2003 engine, it has the 3 square relays. There's no relay with a yellow/red wire going to it. I swapped over 3 relays from my other 8.1 with the 3 on this engine. Still the same issue, that engine starts. I have the wiring diagram for this engine and there's a yellow/red going from the...

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    One place I haven't checked power at is the neutral safety switch. I'm just getting 0 voltage at the yellow/red wire going to the starter solenoid from the solenoid that's mounted under the ECU. Changed it out for a new one and I was still having the same issue with 0 voltage with key turned in...

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    Well, I still the same issue. No voltage at the wire going to the solenoid. I checked voltage going to the ignition switch, cannon plug terminal, 50 amp breaker, and starter pilot relay and it has enough voltage. The solenoid that the starter solenoid wire runs to has no voltage at the starter...

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    Got it all sorted, I ran the wire back to the starter solenoid 8M0185149. No voltage at the wire connected to the solenoid when ignition was turned to start and no voltage at the solenoid where the starter solenoid wire connected. Thanks for all the help!

    2003 Mercruiser 8.1 HO No Crank No Start Fuel Pump Running

    Hello, I'm having an issue trying to start my engine on a stand. There's enough juice in the batteries. Cranks and Starts when the starter is jumped. Fuel pump turns on when the key is turned. I changed out the starter relay with a new one and still the same issue. I've used this ignition...

    Volvo Penta 7.4 GL Slight Water in Oil

    I got my problem sorted out, looks like it was condensation coming in from carburetor. Looks like it had water in the fuel. Have it plugged up to non ethanol and after running checked inside the carburetor and intake and it's dry. Manifolds and Risers are still bone dry. It was hardly even...

    Volvo Penta 7.4 GL Slight Water in Oil

    I understand, I have a set up already to run engines out of water. I'm asking in regards to having that set up having a control box with gauges hooked to it so I can check temperatures and pressures. I have a rigged ignition and key to run engines all day.

    Volvo Penta 7.4 GL Slight Water in Oil

    Do you have the milwaukee one? If you can share what you use that would be great. I primarily work on cars but have had no need on them since I work on only a specific few makes and models and the issues are all the same on them. Boats I have worked on for a few years but as far as water in oil...

    Volvo Penta 7.4 GL Slight Water in Oil

    Do you know if they sell any kits to run engines out of the boat by chance? Oil pressure, temp, water temp gauges and perhaps a control box to increase rpms? Would it work if I increased the rpms on it with a throttle cable and shifter to get it up to temp?

    Luckily dry as a bone with the risers pulled. No rust marks or signs of water intrusion there.

    Volvo Penta 7.4 GL Slight Water in Oil

    I did not change it myself, the previous owner changed it. I'll change it out one time to make sure. It's out of the boat so a bit difficult to get it to run up to temp on a pallet since I don't have gauges installed. It's fresh water. I have not inspected anything as of yet. I was looking at...
