    OMC 4.3

    Looks like someone converted it to a Merc 2 piece exhaust system, these originally came with the OMC one piece batwing exhaust. Mine had those, eventually I had to switch to the 2 piece system and used the ones that were used on later OMCs and Volvos. Here's the old style OMC batwing exhaust...

    OMC 4.3

    You should be seeing more water exhausting from under the transom mount. I used to have those muffs and they are too stiff for the pump to suck in adequate amounts of water. I'd quit using those and get something better. I now use the Merc/Quicksilver round ones with the metal rod clamp. What...

    OMC 4.3

    Also before running it make sure your outdrive is full of gear oil. Dipstick is in the top cover. Remember the gears are all spinning any time the engine is running.

    OMC 4.3

    You are aware that you have to hook up ear muffs & water hose to the outdrive before starting, correct? Or else you’ll burn up the rubber impeller and overheat the engine & exhaust system….

    It’s wherever the boat builder put it. Usually under the helm.

    OMC 4.3

    If your T&T works, but no guages come on and no engine crank, I doubt it is the 50 amp fuse. I bet it's the ignition fuse in the fuse box. Same thing happened to me about 8 or 9 years ago. Especially if you have the old style fuse box with the glass fuses. The metal end pieces oxidize and then...

    1998 4.3 GL Head Replacement

    This is one of the issues with raw water cooling on an inboard. In salt water you get flakes of rusted cast iron that can clog drains and even in freshwater you get sand and silt that can block drains. Rodding out those drains and making sure that everything drains is very important. I have a...

    Flooring Repair/Rejuvenation

    Well it can be done but it’s a LOT of work…when I replaced the deck in my boat 15+ years ago I threw that carpet in the trash since that’s what causes wood rot by holding in moisture if you are in a damp climate. I had a ‘glass shop gel coat the whole deck in non skid gel coat and it still looks...

    4.3LX & Weber Carb Service

    I think there’s confusion about what Weber carb is on this Marine engine…its was made by Weber for Merc and Edelbrock but it’s really just an updated old Carter 4 bbl design that was used in all manner of Mopar products for many years. Not a Weber on a high performance European car!

    1998 4.3 GL Head Replacement

    Sometimes the blocks crack on the inside, where you can't see it till the intake manifold is removed. You'll know more when you get the intake off and can see the block area in the cam valley. These engines were used in Chevy Blazers and S-10 pick up trucks so those heads should be easy to find...

    Check ignition fuse in the fuse box. The old tabs & fuses get oxidized and then things stop working.

    1998 4.3 GL Head Replacement

    It’s just a Chevy 4.3 V6 (probably Vortec) cyl head nothing special. Remove the valve cover & get the casting number & visit a machine shop…

    4.3 LX water in the oil...

    Is it a Vortec engine (intake has 8 bolts instead of 12 bolts like the pre Vortec)? If so these had a bit of a history of bad intake gaskets leaking water or antifreeze into the cam valley. If so it’s a much easier fix than head gaskets.

    4.3 LX water in the oil...

    Any water in the cyls? Is this a full closed or half closed system? If no water in the cyls I’d be looking for bad intake manifold gaskets. That will put water or antifreeze right in the cam valley & motor oil. Head gasket leaks can be confusing to diagnose. One way is to see if you are getting...

    Awfull time launch & retrieve roller trailer

    Your bow stop is too low & you bow hook is probably catching on it. The bow stop should be centered over the bow hook and your strap should be parallel to the ground. I had a similar problem solved easily

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    👍 I had a 1970 Ford Torino with the same engine many years ago. Ford small block V8s were very well regarded. Simple tough old school construction. Mine had a Motorcraft (Ford) 2 bbl carb, C4 auto transmission and Ford 9” rear end.

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Engine sounds good! No weird noises! Just a lil water leak just tighten clamp. Saw dipstick, you keep it in the safe area between the arrows. These dipstick tubes can give odd readings because the oil level in the tube has to equalize to read accurately. Best is to pull the stick out & wait a...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Take a pic of your dipstick so we can see about cranking, I did a compression test last fall with all the plugs out, the ignition disabled, & throttle wide open and I don't think it varied in speed.

    New canvas bow cover rolling at edges, solutions?

    This happened to me once too, what I would up doing was wetting it with water & that allowed it to stretch back into shape.
