    MerCruiser 5.0 Carb Engine Compression Test, Two Piston came back with Zero

    How many is a few years ? Yes I would assume the valves are hung up or the seats are corroded. You can probably pop a valve cover, take the rockers off and smack the valves with a dead blow. would also put some marvel mystery oil in the cylinders let it soak . Typically when engines have sat I...

    Trailer bleeding brakes. Part 2

    Gotta make sure bleeder screw is on up side of caliper. Many time ( not always) they can be swapped side to side and bleeder may not be on up side of caliper. i think the hose comes in on top instead of in bottom of caliper ? my tie downs were in same location. are you bleeding properly put...

    Shiftcable question A1G2

    That’s great was struggling to see how if you don’t remove it how it got messed up on a gen 2 …Did not know it can be clocked differently, assumed it was only in one way… ok yes as long as the roller stays in the shift cable end ( grease will hold it)you should be in business.

    Shiftcable question A1G2

    Doesnt make sense if you didn’t remove … the ccw is from behind the prop. When in fwd the prop when turned ccw will lock will ratchet clockwise. When in fwd turn the input shaft in upper clockwise, propshaft will turn clockwise

    Shiftcable question A1G2

    no, just that the roller on the end can become disengaged from the shift cable end when putting the drive on. did you remove the stainless shift shaft from the lower? See BT drs comments above

    Salt water leak

    Check and see if the clamps or rubber connectors at top of Wye pipe are leaking when the engine is running. If it was leaking at bottom of wye pipe this would leak while not running as it is under water.

    Shiftcable question A1G2

    I’m talking about the lever with the wheel in it that swivels in the bellhousing this can get dislodged from the gray ‘end’ to the shift cable you reference. It will still move the shift lever some just not index correctly. Part number 20 in link...

    Shiftcable question A1G2

    I’m thinking the lever came off the end of the shift cable when remounting the drive . This is in the bellhousing area , usually use grease to hold them together but they make a plastic tool to hold it. It’s like a $8 part… pull the drive back off and I think that’s what you will see. unlike a...

    Never used steel shot in the blaster always used white play sand. If you are going to last the just blast with sand. Wire wheel on grinder works well too does make as much mess as blasting

    Carb Needle condition / function

    As mentioned above you can test with a little air pressure. Biggest issue folks run into is the amount of junk parts being used by rebuilders and sold on amazon etc. Looks are one thing the cheap ones can get hung up or leak where it threads into bowl top. Make sure float is in good condition...

    Carb Needle condition / function

    As mentioned those are the idle mixture screws one for each bore. someone hammered them down tight damaging them - get replacements from a place like mikes carb parts. Are you rebuilding the entire carb including needle seat and float? The engine would not run with the mix screws closed off...

    Alpha gen1 ? Help to identify with pic

    I think I caught your drift by related you mean to the drive lube poppet. It is a male fitting on the bellhousing and female on the drive so can’t imagine that broke but possible What he probably broke off is the speedometer tube fitting. It’s down by the shift shaft/ lever in lower. You push...

    Alpha gen1 ? Help to identify with pic

    BY related to the drive itself what do you mean? They are different drives and not bolt in replacements of each other if that’s what you mean. There are some parts commonality but shift mechanism is different where drive and bellhousing shift shaft meet Did you friend break off the poppet...

    Alpha gen1 ? Help to identify with pic

    That is the poppet valve for the gear lube. Must be a gen 2 drive , connects the lube bottle on engine to the drive so you can monitor lube level and get an alarm if low alphas switched from gen one to gen 2 in 1991 timeframe.

    Alpha one gen II leaking water near hydraulic hoses

    I would also drill into the stringers in the engine bay and ski locker or by gas tank if you can take the floor out to access. Biggest thing to do at this point is get a handle on the extend of the rebuild and then guys here who have done it can help you SWAG the cost and make a intelligent...
