    Crud in carburetor, is it a problem?

    i meant once you verified the timing is ok likely this is related to carb being plugged up Or some type of fuel starvation. If you get it successfully cleaned out and are feeding it with clean fuel you should be ok after that

    Crud in carburetor, is it a problem?

    Back to the OP, completely disassemble the carb, clean all the passages, makes sure the fuel filter in the bottom of the fuel pump is clean or replaced, verify clean fuel supply to carb , check fuel pressure/adequate supply . I would think having verified timing the above would take care of itb

    Common crack area from housing corrosion. If you are handy you can get a good used housing swap your internals. That’s what my buddy did with identical crack On his B3.

    Mercruiser alpha one small amount of water in shift cable housing

    Use a bolt as a homemade puller to pull the seal into the housing. Put the bolt through the seal and housing, slide a washer and nut on threaded end tighten the nut to pull the seal into place in the housing. It will be a light press fit. you can’t use a seal driver or socket to push it in as...

    357 mag bravo 4v long block replacement

    The bravo 357 mag is rated at 325 hp so I believe the long blocks are the same, but as mentioned you may be able to just get away with valave job and head gaskets. if I haven’t you may want to check pricing at michigan motorz on long blocks and crate engines if u go that route. I had a nice...

    1990 Mercruiser 5.7/v8 rusted exhaust manifold bolt

    Lots of heat at the base would be my first attempt that not working the head will break off or cut it off with a grinder so the manifold can come off, if us are lucky you will have a headless bolt sticking out , more heat penetrating oil pipe wrench or vice grip on shaft of bolt sticking out of...

    mercruiser 140 head

    I think yes it is but you also may want to check the intake and exhaust ports line up on the manifold. Back in the day I think they offered multiple hp versions of the 3.0 like 115 and 135 hp. it may also be a head of the 2.5 which was the little brother of the 3.0 , at work just the same just...

    Broken Spindle?

    Looks like you have had inner and outer bearing failure and the bearing races are still on the axle , may need to be cut off the axle . Buy new bearings, with a cutoff wheel and chisel take these inner races of the axle. You may need to clean up the axle with a file But as long as the inner race...
