    lifter issue and rock arm registration

    Just remember if you are doing this, it helps a person who just pulled a 4.3 out of someone's old S-10 Blazer or pick up and just wants to get their boat in the water. All the questions lead to learning which helps others which is really the point of these forums!

    Especially in the case of the Chevrolet small block series both V8 and V6, there are many variations.

    Quadrajet Replacement Options

    a better fuel filter is good, but you can't use that model in the bilge of a gas inboard, the bowl has to be metal.

    BEWARE of Faulty 87290A4 Thermostat Housing sold on Amazon!

    I have had good luck with Barr Marine exhaust parts but I would always check with a straightedge and feeler gauges if both the manifold & elbow sealing surfaces are flat and level to less than .003".

    Very nice work, isn’t it satisfying when you get to this point?

    Quadrajet Replacement Options

    I suggest you head over to Cliff's High Performance Quadrajets and join that forum and ask there. He's one of the recognized Q-Jet pros and what he usually says is that the reman Qjets that you can find online, are often "franken carbs" which is a collection of parts that don't work together...

    Quadrajet Replacement Options

    You know I tried a brand new Holley 4160 on mine (the specific one that is jetted for the OMC and Volvo 4.3) when I thought that the Qjet was too old to rebuild and had no end of trouble with it. Rich running, fouling plugs, not matter what adjustments were done. Pulled the Qjet out of the...

    BEWARE of Faulty 87290A4 Thermostat Housing sold on Amazon!

    I have a few GLM parts for my Cobra because frankly there is no more OEM for some items but for critical parts like manifolds I use Barr Marine and for a stat housing I use OMC or Volvo (same part). I don’t like Amazon for automotive or marine parts. I use marine engine . com for OEM and decent...

    VP drive failed again ... 3rd replacement

    That sounds like some VP mumbo-jumbo making an excuse for a flawed painting process.

    Quadrajet Replacement Options

    Since you have a Merc rigged engine and Merc used the Weber 4bbl after Rochester quit making Quadrajets keep in mind the Weber & the Edelbrock are functionally the same. In fact I read somewhere that Weber actually makes the Edelbrock for them. Meaning that adapters for the throttle linkage...

    Tinkering on the 4.3l this winter...

    I think in your size/weight boat you'll be happy with the 4bbl. Keep it simple, less possibly for problems down the line. Think about stepping up to the Mercruiser/Quicksilver 25/50 syn blend oil. I think it tests out better than 15w/40s on UOAs from what I have seen as far as holding its...

    How easy is it to replace the seals on a 50 hp Johnson trim/tilt myself

    You can use heat on the end of the cylinder and then force the pins into the cap as much as you can when turning the pin wrench with a ratchet.

    How easy is it to replace the seals on a 50 hp Johnson trim/tilt myself

    I did that job on my old Cobra drive this past spring, the tough part is getting those caps off, if you can do that, the rest of the job is pretty easy. BRP still sells the seal kit for the Cobra drives, it could even be the same thing for the outboards but I don't know for sure. I had a spare...

    lifter issue and rock arm registration

    Did you blow compressed air through each pushrod? I might crank it over with the ignition disabled till you see oil reaching all 12 rocker arms…just crank it for like 10 sec, then let the starter cool, repeat etc.

    Bilge Pump Upgrade

    In addition to maintaining/upgrading bilge pumps, anyone with an I/O or inboard should always check ALL cooling hoses at the start of each season, for tightness and condition. I had a cooling hose between the transom mount and the P/S cooler (tough to get at) pop off some years back, that caused...

    Boats from work.

    That's the problem with 'glass boats, you always wonder if the one you are buying was built right in the first place, sometimes it takes years to find that out!
