    Overheated, need help identifying pink liquid-

    Yep might have melted a ps line or power trim line if equipped. Things to replace: Any rubber hoses aft of the exhaust elbows and any rubber hoses, cables or wiring in close proximity to the exhaust system. Exhaust flappers if so equipped.

    OMC cobra trim only going down not up

    Exhaust bellows not critical at all but the one above is critical. You need to make sure each relay has power, ground and is getting the up or down signal. The problem can be in the connections at the relay or at the remote control switch/wiring Concentrate on the blue wire that is the up signal...

    OMC cobra trim only going down not up

    The older Cobras use the big relays like the old Ford starter relays. Make sure all the terminals are clean; and they have power and ground. From the remote control the blue wire is the up signal and the green is down. Sometimes the wires break inside the control.

    Volvo Penta 3.0 GLP-D (PCV valve popping off while running - carbon buildup on boat thru exhaust)

    for it to really function as a PVC it has to be connected to manifold vacuum, I"d like to see where it is connected on the carb.

    Time for a ‘new’ boat?

    Hello Ted, What was the engine misfortune? I must have missed it... Anyway I found it interesting that you will stick with the I/O, there are some advantages but the main thing that would stop me (smaller boats) is bad access and cat converter exhaust. The complexity now in inboards has caused...

    Volvo Penta 3.0 GLP-D (PCV valve popping off while running - carbon buildup on boat thru exhaust)

    If there is an actual PVC valve in the valve cover instead of just a hose leading to the flame arrestor to take care of blow by, yes if the valve gets stuck blow by building up in the valve cover has to escape and can blow it out if there is a lot of blow by. That Holley carb does have the...

    5.7l mercruiser gen 1 alpha 1 to vortec head swap problem please help...

    The QJet I have on mine is the original carb this engine came with and when I replaced the heads 4 years ago I stuck with the pre Vortec heads so I didn’t have to change the jetting in the carb which is pretty close to ideal judging by how the plugs look (light brown). I agree with signing up at...

    How to tel if boat will over heat in the water

    If its the same as the Cobras that housing has a rubber ring inside to hold the 'stat in the housing. Might want to replace that ring too if it hasn't been done in a long time. The standard stat was a 160* unit.

    How to tel if boat will over heat in the water

    Agreed water test is the only way. Try to do it early in the AM when no one is around, let it idle to warm up and see what it does. Perferably till the thermostat opens, you may have to run it above idle a bit (1200-1500 rpm) to get it up to temp. Just make sure the water is deep enough to fully...

    7.4GL temp sender info needed

    I think these engines used a 140* thermostat vs other Volvo engines that used a 160* stat. I actually tried this same stat in my OMC because the lower temp stat is better for raw water use in salt water. And it does show on the gauge approx 120* at idle. At higher speeds it rises as expected to...

    Impeller challenged...?

    If you are careful you can measure that with a ruler and a small T square. I do have all the tools though. One other thing I did, was mark on the cable where it goes into the jacket, where neutral is with a sharpie. Then have someone spin the prop (engine off KEYS OUT) while I shift it into FWD...

    1987 4.3 OMC Alternator with 1 Wire Issue

    When I replaced mine I used an ARCO with the B+ terminal and Excite and Sense terminals, the hook up was easy and it has always worked well.

    Bow riders with best engine access?

    beautiful boat! and yes the bigger it is, the more room around the same size engine in most cases. so tell me can you actually reach the starter? and how do you feel about the $5000+ price tag for the cat converter exhaust replacement? If in fresh water its a non issue but here in the salt, I...

    Bow riders with best engine access?

    I have see a few that have good access but its usually the larger boats that do, large bow riders, cuddies etc. You don't want the ones with the build in 'glass around the rear jump seats, or the fancy swim pad with the walk through or the flip seats that make the engine compartment 2/3rds the...
