    350 mpi rebuild questions

    Exactly while many on here have said they used automotive gaskets successfully not sure why you would screw around over $100 cost diff being this deep into it.

    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...

    Mercruiser 165's First Engine Align, Having Trouble

    you can use timbers spanning the gunnels no issue. Could also hang a chain fall off a roof joist They are not that heavy so you can shove the engine around a bit when on the front mount. were you able to get any witness marks on the tool to show you which way top go? You would be best to...

    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...

    Mercruiser Gear reduction and prop

    While it is removed check the gimbal bearing and u joints, if there is no water intrusion into the bellows are likely ok. While drive is off pressure test it to assess seal integrity. check out the igntion components see what the plugs look like

    Mercruiser Gear reduction and prop

    in a nutshell Yes higher pitch will lower wot rpms, lower will increase holeshot and increase wot rpms. as mentioned above try the boat out and see where your wot rpm lands before doing anything. depending on if your engine is carbed (220 hp) or mpi (260 hp) It will have a range of 4400-4800 rpm...

    Mercruiser Gear reduction and prop

    I would think even with a 1.62 ratio 23” pitch would be too much. you sure the 1.52R is nit actually a 1.62 that would make sense with the ratios which were 1.47, 1.62, 1.81, and 1.98 verify what the ratio is and try the boat out see what you get for wot rpm before playing with props. Really...

    Mercruiser Motor identification

    Makes sense that they just put in a new long block. Surprised merc don’t take it back as a core. The issue you will run into is are the peripherals needed to make it a running engine are all proprietary parts. I’m assuming you were thinking it was vortec based? Maybe the factory intake could be...

    Alpha one gen II leaking water near hydraulic hoses

    The products like sea cast that are poured in are fine replacements once the wood is hogged out. You can find some vids where people do them cutting the wood out with a chainsaw, issue is you need to pour it in from the top which is easiest done on an outboard boat. you Likely can sell the...
