    This charge coil goo normal ... doesn't look right to me.

    I'm troubleshooting inconsistently going into S.L.O.W. mode on my 1990 40 Johnson. When inspecting the ignition components, I noticed the charge coil is leaking black rubber sticky stuff; as seen in the pics. That's not normal, is it? I originally thought it was the ignition module causing...

    Boat cuts out at idle

    My boat shuts down at idle. It does fine at higher rpms, even idles fine after running for a while. When the engine has been off for a while (30-45 min) it does it all over again. I've replaced the IAC valve and the issue is still present. If I put it in neutral and raise the rpms a bit when...

    Need help confirming I can use this engine wiring harness.

    I have a 1994 5.7 GIPMDA. The engine wiring harness has to be replaced and I can't pay the 1200 Volvo wants. I thought it could be repaired, but there are 7 or 8 connectors that have to be replaced; not to mention there are several frayed wires in each of the ECM connectors. I have the Seloc...

    So I made a big mistake yesterday. I broke the fitting that connects to the elbow of my oil pressure sensor off. I was trying to get the oil pressure sensor off and I applied too much torque and it snapped off. Part # 84 in this pic...

    How do I replace a circuit in my wiring harness?

    I have a 1994 5.7 GIPMDA. My boat has been acting weird. I have, I believe to the troubleshooting in the manual, traced it down to an open tps circuit. I'm getting a code 21. According to the Seloc manual it is a result of an open circuit 417; the circuit that sends the signal to the ECM...

    My impeller disintegrated, where are all the pieces?

    I must have put the cam in wrong when I installed the impeller and it somehow caused the impeller to be torn to shreds, literally. I've taken all the hoses associated with the cooling system and the thermostat housing off to look for pieces of the impeller. Also, I've looked in the oil cooler...

    I have a leaky raw water pump, now what?

    Lately, I've noticed my raw water pump has started leaking. After taking it apart twice and checking the gasket and impeller for signs of wear and damage, I have come to the conclusion that a seal on the front of the pump is the culprit. My pump number is 3851623. When I looked up that part...

    Broke yet another steering helmet, Argghhhh

    This is the third time that I've snapped a steering helmet. WTF is going on here. I've looked on ebay for replacements and the two I've found don't look like the one I just snapped. To make it worse, I can't even read the part number on it. I'm hoping one of the senior members here can help me...

    How do I lube my steering cable again?

    So I'm reading up on steering system maintanence because I hear a noise coming from the back of the boat while turning the wheel. According to the manual the steering cable should be greased every 60 days. I take a look back there and don't see where the steering cable could be greased. The only...

    Is 5 qts of oil enough for a 5.7 ?

    I have a 1994 5.7GI. I did the begin of season oil change yesterday. While looking up how much oil to buy I looked in the Seloc manual (pg. 2-65) to see how much it takes. According to the Capacities chart it states that it takes only 5 quarts. Is that right? That seems a bit to little for me...

    Are some sea water pumps rebuildable?

    I don't remember my water pump leaking. However, recently it has started leaking. It appears to be coming from the front of the pump (pic 2)not the the back where the two halves come together. There is some sort of rubber seal (pic 1)on the front of the pump that I think may be the cause of the...

    Oil pressure sensor bad?

    During the week I decided to do some "cleaning" up of my boat engine. Scrubbing this and that corrosion of sensors and what not. After cleaning up my oil pressure sensor switch connections I tried putting it back on and it seemed to not go back on like it should. The post the hex nut screws...

    Engine makes a knocking noise when in neutral .... what could it be?

    A couple of months back I replaced my PDS bearing because it was shot. Everything was fine for a couple of weeks. All of a sudden the engine ( I think its coming from the engine) started making what sounds like a knocking noise when the boat is in neutral. The u-joint snap rings seem to have...

    Know the water circulating pump replacement auto equivelent?

    The bearing on my water circulating is starting to fail. I surmise it from the fact that the pulley attacked to it has some play forward and aft. The other pulleys do not, e.g. raw water pump, power steering, alternator. I have a 1994 5.7 GI. I tried getting a replacement for it at my local...

    Ran out of gas, now the boat won't run ....

    Yesterday my boat ran out of gas. After filling it up with about a quarter tank I attempted to get on plane and the engine surged a few times and then died. It did it a few times so I took the boat out of the water. A friend suggested the fuel filter may have sucked up something from the bottom...

    How to pick the right winch for the boat ...

    The latch that holds the winch tight when the boat is winched on my trailer broke. Now the winch just free spins. I can use the winch to get the boat on the trailer, but have to use the safety chain along with the straps on the back to keep the boat on the trailer when on the road. I've been...

    What does this nipple grease?

    I was doing my yearly spring maintenance and noticed a nipple that I've never greased. Its close to the steering arm behind the engine. I took a picture so you can see what I'm talking about.
