    Blowby through vent tube? Mercruiser 3.7

    I feel for you. Have seen it before. Bore not to specification for the rings and or piston used (or vice versa). Always appropriate to double check dimensions during assembly, but most people don't. All it takes is a brain fart on the machine shop part, which we all have on occasion. Most home...

    Why is my carb oxidizing????

    The whole top of the motor looks like water drips on it all winter.

    Shift interrupter operation and adjustment after restoration

    They were quite a bit more way back when I swapped to EST.

    Shift interrupter operation and adjustment after restoration

    Chris commented towards this, and I must strongly support his comments. Boats are buckets. Gasoline fumes are heavier than air and sink. They have no where to go in a boat bilge - unlike a car or pickup where they drop out the bottom onto the road surface.. There are loads and loads of deadly...

    Why is my carb oxidizing????

    I kind of wonder if shrink wrapping holds a lot of moisture inside? And if a dehumidifier in the engine compartment would help over winter?

    A couple of quick Edelbrock ?'s

    Easiest of any carb to work on, generally speaking. Long as the little shiny round things get back in the right holes...

    03 4.3 carb and manifolds

    Your '03 will be a Vortec motor. While you may eventually want a 4 barrel, to do that right would also need a manifold designed to flow the 4 barrel. I'd run it until Edelbrock gets back in stock and look for a manifold to hold the new carb up properly. Was the boat a salt water or freshwater...

    Yup. Nailed to the wall with my own ignorance :D

    Questions about my Mercruiser 4.3

    From what I can see, he has a 93 block with v-belts. That means steel pan and timing chain cover. Good combo - and no balance shaft either. Needs fluid motor mounts though.

    Questions about my Mercruiser 4.3

    Note, I have virtually the same setup. A '93 block with Vortec top end. A frankenmotor. Have to use multiple manuals to work on it.

    Questions about my Mercruiser 4.3

    Vortec head engines hit Merc in '96. Someone must of swapped out the heads and intake on your motor. That's a good thing. Your block is obviously not originally a Vortec as it has v-belt accessories.

    Engine stalls when put in gearMy boat is a 1979 27 ft Carver Monterey Mercruiser 228 305 4barrel - Alpha Drive The engine stalls when shifting gear

    As stated, replace lower shift cable. Is possible your temp gauge isn't working right?

    Can the base of engine work? Two to bolts under engine are rusted and can

    The lag bolts for the front mount have nothing to bite into. You will need a way to rebuild that crossmember so it is solid again. If the lag bolts won't screw in tight the motor moves and the coupler gets destroyed.

    Engine stalls when put in gearMy boat is a 1979 27 ft Carver Monterey Mercruiser 228 305 4barrel - Alpha Drive The engine stalls when shifting gear

    Replace the lower shift cable. It is a wear item. As it ages the inner cable wears into the outer sheathing, that's what causes added drag and actuates the shift interrupt.

    Starter Wiring, 4.3L Mercruiser

    4th terminal is for running prime power to the fuel pump during cranking. Without it you will have trouble starting your motor. As Bondo said, wrong starter.

    Mercruiser 200HP 305 CID V-8 Normal Operating Temperature

    Water type is not so important - open cooling is the issue. Since with sea water cooled motors there is no pressure built up, the water in the engine will start to create bubbles on the walls of the water passages at anything over 160ƒ. Heat transfer is significantly impeded by those bubbles and...

    Alpha 1 gen 2 5.7L overheating

    Most rubber parts bought OEM from Mercruiser will last longer than aftermarket. Especially true of bellows, but also of impellers. Merc gets the rubber right every time.

    Alpha 1 gen 2 5.7L overheating

    No. Purpose here is to find out if any water is getting through the impeller. That test is fine at idle on muffs. Best place to start to find out if the impeller works at all. Silly to haul it to a boat ramp just to find you don't get any water through the impeller.

    Alpha 1 gen 2 5.7L overheating

    First thing is to pull and hang the IN line at the thermo housing - the one coming from the oil cooler and transom. Hook up muffs, water full on, fire up. Do you get at least 5 gallons a minute flow from that hose? If not, then something is plugged or impeller is bad.
