    Boat Voltage Question

    I had a similar problem on my '88 FW with the OMC engine wiring harness and the Medallion gauges harness. What I had was low readings at the dash gauge, like only 12 V --12.5 V with the engine running, yet the alternator output was 14.2V as was charging at either battery. So I thought it was...

    OMC 5.7 V8 power loss

    Scott I think the Weber on Mercs is actually a Carter clone as is the Edelbrock. Edelbrock did build Quadrajets after GM quit making them for a while but I don't know if any were marine units. The tricks to doing the Quadrajet rebuild (getting the air horn off) are driving the pin that holds the...

    What is this? Every so often I will get this when logging on, its something that looks like its prompting you to download the latest version of internet explorer, then the virus protection identifies it as a virus....

    4.3 MerCruiser Starter Problems

    I use a spare battery I keep in the garage and a momentary switch (remote starter switch) to test starters. Be careful because the torque reaction will cause it to jump a bit as it cranks. The previous owner created quite problem for you there. I don't think that can be fixed without replacing...

    Exhaust Manifold too hot to touch

    don't forget to check the little by pass opening in the OMC/Volvo thermostat housing... at idle you should be barely warm (90-100) after coming off plane 125-130 or so. I have the exact same exhaust on my OMC and that's what I get consistently.

    Cobra drive cooling problem

    OK keep in mind that the Cobra impeller is in the upper gear housing, about 18" above the level of the water intakes there is no way on earth it will prime in a bucket, garbage can, etc. That will only work with outboards were you can submerge the lower unit BELOW the level of the impeller...

    Volvo Penta 5.0 GXI-G Riser problem.

    about the only thing left is the cooling passages inside the manifold and elbow (what you're calling the riser is actually an elbow) you might have to drain the water out of the manifold and remove the elbow and see what it looks like. Here's what a VP style manifold looks when new....you may be...

    hope you can see this the dimension is 7 13/64" or 18.3cm, measured from the top of the shift rod head to the drive housing surface (where the water passage cover is bolted on to.. PS I had mine set up at a shop back in 2004, because I was having shifting problems like it would not come out of...

    Looking for bare engine block with pistons

    Excellent work looks great! Probably the most immaculate Cobra install I've ever seen! I did get my boat in, I was held up a bit waiting to get the bottom paint done but will start using it soon! Today my son and I replaced a faulty rear door window regulator on our old '98 Jeep. Not the easiest...

    Mercruiser 1987 260/5.7 thermostat/water priming before startup

    Agreed the problem with running an outdrive in a drum is that it can’t go up high enough to fully submerge the impeller and keep it from sucking in air. Also your exhaust water is heating the water in the drum as well. Get a marine thermostat 140 if in salt water 160 if in fresh water and use...

    merc 260 q-jet fuel drips from boosters

    I had this on mine (nozzle drip) and it was just as Kenny said. I soaked it well and used a real compressor not canned air to blow out the idle air tubes. You can run it that way though, it won't really hurt anything. If you have an original un-molested Marine Q-Jet DO NOT exchange it for a...
