    Mercruiser 5.7 wanting to stall at idle after driving around

    If you got it from Cliff with the # on the carb it is likely right

    Mercruiser 5.7 wanting to stall at idle after driving around

    Also when you install the needle valve in the float arm, make sure that little clip is not in one of the holes but on the side. If it’s in the hole, that can cause the needle valve to jam and flood the engine. As far as the variations best bet is to use the Rochester carb # on the side of the...

    spring vapor lock?

    Bad elbows & manifolds are the #1 cause of inboard engine failure in saltwater. If you have a Merc I’d consider upgrading to the better dry joint system. A bit more $$ but better design. Still have to replace regularly in salt but the risk of leaky gaskets letting water in is much less...

    spring vapor lock?

    Did it get as high as the starter? If so might want to replace.

    spring vapor lock?

    Right if you see rust on the outside it could be leaking on the inside into a cyl via an open exhaust valve.That if left unattended over the winter can lock up an engine.

    Has anyone seen or heard of a trailer tire doing this?

    I think jacking the trailer and rotating the tires every few months can help because what I noticed with the last set I replaced was that the majority of cracks was in the spot where the tire sat for over a year when I was making major repairs. So now every 2 months I jack it up & spin the tire...

    Mercruiser 5.7 wanting to stall at idle after driving around

    That can also be fuel boiling in the bowl from high temps. The older pre Vortec has a heated intake and the QJets used a thick insulator gasket. With that gasket I have not had a problem with fuel percolating in the carb

    carter mech fuel pump

    I would just use whichever gasket matches the flange on the pump/block better. There is oil in that area so you don’t want a leak there

    carter mech fuel pump

    I used a bit of Permatex Aviation on the threads. Not sure about the 2 gasket question don’t recall if mine came that way have to think back.

    Mercruiser 5.7 wanting to stall at idle after driving around

    A common problem on the QJet is the idle air tubes get clogged, these can be carefully cleaned out with carb cleaner a very thin wire & compressed air. Cliff has instructions in his forum on his website on how to do this. Do you have any nozzle drip at idle from the venturis? Take a look.

    Has anyone seen or heard of a trailer tire doing this?

    Or consumers being cheapskates discouraging quality tire companies from making consumer/recreational trailer tires at all.

    Two Layers of 3/4 CSM versus One Layer of 1.5 CSM

    I used stainless L brackets to secure Mahagony cross pieces over my tank. Supports the hatch cover very well. This was done way back in 2006/2007.

    Ford 302 spark plugs

    looks to be running quite lean, you would like to see a tan/light brown color on the center insulator. At least it doesn't seem to be burning oil!

    Ford 302 spark plugs

    If it’s under warrantee might be better not to touch anything other than making sure there is oil in the crankcase and no water in the cyls

    Fuel pump whine

    Might want to run it on an outboard tank temporarily just to rule out the anti siphon valve & tank pick up.

    1996 215 SeaRay EC engine alignment

    Did you coat the end of the alignment tool with grease & look at the witness marks? Ujoint condition?

    Ford 302 spark plugs

    Remove spark plugs & valve covers & see if will crank over with the ignition disabled. Look for normal valve train movement & see if water comes out of the spark plug holes. That will also reveal if something failed in the valve train.

    Burned Impeller

    Keep in mind that the water muffs force water in under pressure which is not the same as running it in the water. I would back it in at your boat ramp & if no one is there run it for a while to check temps & make sure there are no leaks from the exhaust hoses. An overheat can burn the exhaust...

    Ford 302 spark plugs

    I would not go by that tag so much but the actual Rochester number on the casting. Those are listed in the page you posted. Not sure where it is on the 2GV but here it is on my Quadrajet 4bbl. Even then you don't know what jets/metering rods it has inside till you look. That's the problem with...

    Bought a new long block and wondering about the coupling and gimbal bearing.

    I'll never forget the first time I drove a US built car with EFI. My inlaws 1987 Mercury Grand Maquis with the Ford 5.0. Get in, turn the key and a nice smooth idle, no fast idle needed, no matter how cold it was out. Had to break all my time worn habits with carbs. Back in the carb days we...
