    Wrong New Prop Or What?

    I want to revise my last post.... I am a geek, owner of MacGurus for the last 20 plus years.. I also own and run a welding/fabrication shop. I want to never stop learning. There is no reason a technologist such as yourself cannot get familiar enough and educated enough with your boats power...

    Wrong New Prop Or What?

    Well, this thread appears a pretty much waste of your time.

    Wrong New Prop Or What?

    I was going by this sentence: You maybe stated that with a different meaning, but it implies there is a magic solution in a rebuilt carburetor box and the service won't have to calibrate the new rebuilt. My point is, there is little to zero likelihood of getting a drop in rebuilt carb that is...

    Wrong New Prop Or What?

    I got that you aren't going to do the work. But I also get that you have no idea what the mechanic is going to do, can do, is willing to do, or even should do. Your comment about the mechanic not being willing to rebuild the carb, yet willing to install one that is rebuilt without having to jet...

    Wrong New Prop Or What?

    I gotta tell ya, unless “the best marine service” took the carb apart, rebuilt it and recalibrated it with proper jets, they didn’t do much of anything to be called “adjusted”. There are two adjustments on the outside of a carburetor. - idle mixture and idle speed. That’s it. Neither one has...

    Wrong New Prop Or What?

    I would even more suspect water in fuel, dirty carburetor innards and crudded up filters.

    Mercruiser 140 barely running and running rough

    Somethings plugged up. Yes, your most likely suspect is a carburetor needing cleaning.

    1999 bayliner vibration

    Note, a gimbal bearing driver is relieved so it only impacts the carrier, not the bearing. The bearing is taller than the carrier and using a tool that is not relieved will destroy the smooth surfaces inside the bearing itself.

    Mercruiser 3.0 TKS problem at cold air temperatures

    Clean and kit the carburetor. You got something plugged up. Check your fuel water separator as well for contaminants - dump into a clear glass container and look to see.

    4.3 Starter mount area cracked

    Most common cause of hydro-locking is a crack in the exhaust manifold letting water in on top of your exhaust valves and into the cylinder. Need to inspect the manifolds carefully to be certain they don't have cracks.

    1999 bayliner vibration

    Don't run it until alignment is perfect. May need to pull engine to make sure all the mount parts are present in place and/or not damaged. Also check transom and stringers for dry rot - which should be called wet rot. Take a drill and mark it with tape so it goes in no further than 1 1/4". Drill...

    1999 bayliner vibration

    I saw a sealed u-joint in a new truck that had no grease in it. I have seen a few u-joints missing a couple needles. When in doubt, suspect even new u-joints. Did the alignment get checked when the work was done on the drive shaft?

    Grounding coil for compression test

    Even though it is not the recommended way, I just pull the coil to cap wire. All gonna die one day anyway.

    4.3 Starter mount area cracked

    4.3L blocks being as common as they are, I'd most likely plan to find one and swap over my external bits and pieces after marinizing it. Your's being a '96 makes it dead easy to find replacements.

    Flooding...

    You can disassemble starter and alternator. Use electrical parts cleaning spray - a common CRC product - to clean everything up and then lube what needs. Impossible to get water out of wires. Somewhere down the line that can cause corrosion issues. Did you also sink the trim pump? It also can be...

    Time to reassemble

    That's what public forums are good for - making oneself smaller. I do it regular like.

    Time to reassemble

    The movement you see is also from the throttle cable, not just the shift cable which moves exactly 3 1/8" on his controls..

    Break in fresh built mercruiser 230 out of boat

    IMHO it is a waste of time. Seating rings is best done under load.
