    Replacing 95 merc 4.3 with 87 OMC 4.3

    OMC did not use the triangle shaped coupler it’s a cylinder shaped one with studs that go into the flywheel/crankshaft and nuts that hold the coupler to the studs. Just like what’s seen on a Volvo SX in fact probably the same part! I used a PMGR starter to replace the old Delco starter on mine...

    If you get a really bright led inspection light & shine it in the bellows you can see the internal splines in the coupler; they should be squared off not rounded off. You have a vib since this engine was installed correct? I’m thinking of other sources….engine flywheel? Harmonic balancer...

    In the 1st 2 pics it looks like the tool didn’t go all the way into the coupler, more like about half way.

    MerCruiser 5.0 MPI pinging/detonation at higher RPMs

    I’m looking for a newer Grand Cherokee I already have 2, a 1998 6 cyl and a 2007 Hemi V8. Next one V8 or nothing.

    MerCruiser 5.0 MPI pinging/detonation at higher RPMs

    I still have the one I bought in 1973 or so. One end is for the Chevrolet, the other end is for the Ford. Had one of both in the old days, a 5.7 liter Chevrolet and a 5.0 liter Ford. just like this, the 9/16ths was Chevrolet, the 1/2" was Ford...

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    While getting the distributor installed properly & adjusting the hydraulic valve lifters at first seems confusing if you watch enough vids it will start to make sense. When I replaced my cyl heads I had done mechanical valve clearances on VWs, Hondas, Mazdas but never did a Chev with hydraulics...

    MerCruiser 5.0 MPI pinging/detonation at higher RPMs

    I don’t think there should be any movement of the distributor or cap. Something’s worn or not right there.

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    Ok if you have a pre Vortec engine (‘95 and older) the valve train is adjustable and you HAVE to adjust the hydraulic lash adjusters. The later engines have non adjustable valvetrain & those you just torque to spec.

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    Doing the hydraulic lifter preload adjustment on an SBC is actually easier than setting mechanical valve clearances.

    Can I replace a Mercruiser 5.0L with a 4.5L engine?

    Also check the parts prices for that Merc 4.5, when Mercruiser took the old cast iron GM 4.3 design and slightly re-engineered it, they made it more complex and jacked up the price of many parts 2-3x what they were in the past. I wouldn't reward Merc's greed and BTW, you can still buy brand new...

    Wix filter cross reference for VP 4.3?

    My brother has a 2020 Merc 4.5 200 hp and it’s the same as that; instant starts, smooth running day after day. Just like modern cars. I’m old enough to have had new/used cars with carbs & know the good & the bad with them. Quadrajets, 2GVs, Autolites & Holleys.

    If I recall correctly the older Volvo fuel pumps for port fuel injected engines were a low pressure & high pressure unit and retail on them was about $1000. Yes fuel injection is great better cold starts & running & idle smoothness but you get slammed with parts cost.

    Boat trailer brakes

    If the full up weight is 7500 lbs a pair of 3500 axles are overloaded and the next step up is 5200 lbs. There are 3750 lb axles but not commonly available. And those leave no safety cushion so the 5200 is your best bet. If you get drop axles like I did you won’t raise the trailer either. You...

    Boat trailer brakes

    I did something similar switched from a 3500 lb axle with 10” brakes to a 6000 custom axle with 12” brakes. I did this because the frame of the trailer was the same gauge as trailers with heavier weight ratings. Axles, rims/tires, & springs all should have close to the same rating in terms of...

    For Fuel & oil filters I have used Sierra; not sure if Volvo used the OMC thread size mount or not; also you can use a Merc oil filter if yours is mounted on the block; if remote mount it’s probably not the same as the block mount filter. I FINALLY got a remote oil filter mount for my 4.3 with...
