    New gimbal bearing, can’t get alignment tool in coupler

    yes rear mounts can sag, and as pointed out the transom integrity in an older boat is also suspect. If the mounts were sagging the coupler would be lower than the gimbal bearing when viewed through the bearing. If you can take a pic through the bearing and see the coupler we might be able to...

    3.0 mercruiser valve adjustment

    yeah your other boat is ok. I had a 3.0 for 20 years after 800 hrs pulling tubes and skiers still had 140-145 psi, which given how many hours it was above 4 k rpm is pretty amazing. if you replaced the rockers, balls and nuts maybe you have a parts mismatch ? Maybe try a set of poly locks?

    Block sealant...in a raw water system

    I think you will have best luck with JB weld, which over time probably will break off eventually. Hey if it leaks a little but doesn't get water in oil, who cares. Center State Engine was selling reconditioned bare blocks on ebay or be patient you can probably find a good running tear out.

    Tire Pressure

    Over inflation can result in premature wear in center of tread, if you don't see more wear/less remaining tread depth down the middle of tire I wouldn't worry about it https://www.pakwheels.com/blog/dangers-inflating-tires/overinflation/

    5.7LX rebuild question

    You can use your shift plate, but unless you swap a alpha ignition module for the bravo ignition module the shift interrupt wont work. if you look into it they (Merc) make these Gen + crate engines in both alpha and bravo configurations with different hp ratings . Same with the alpha bravo 357...

    5.7LX rebuild question

    The 325 is a mercruiser crate engine intended for bravo drives. The silver package is a partial engine MM puts together from a new base engine. If you have an alpha drive the 325 hp one wont work due to lack of shift interrupt with the bravo TBV ignition module. I think merc makes a 300 hp...

    Anyone use a 2017 kia Sorrento AWD/4wd high output engine?

    For ten miles you will be fine just use your head and take it easy. If you end up towing it longer distances rent a pick up or uhaul truck.

    I bought a 5.0 silver package plus manifolds and elbows off Them six years ago When i repowered from a 4.3. They tweaked the kit to eliminate the fuel pump and substituted a tbolt distributor for the delco, maybe they will do the same for you? I just preferred to stay with stock merc ignition...

    Random knock over 4k RPMs...

    Check the filter and dist cap as advised first. I use ethanol pump gas in my seadoo for years , no issue in the spring. So many issue blamed on ethanol without due diligence troubleshooting,

    Motor question

    is the amberjack an inboard or something like a TRS drive that uses a separate transmission ? Are you looking at swapping complete drivetrain or just the engine and use what is in the sundancer ? I assume sundancer is outdrive ?

    Buying a automotive engine to replace my mercruiser, need opinions

    In addition to the cast impeller a marine water pump is bi-directional not sure which belt configurations drive it the opposite way than it would be in an auto configuration. Normally a truck cam would be ok but I think this is bigger than a truck cam. I think the 230 deg duration @.050" would...

    I think some folks mix the two stroke and fuel pour it into fuel filter when changing, run it a few seconds. to get oil gas mix in engine. come spring the small amount in the filter is quickly burned off during start up

    Are Merc Mc-1 and Alpha 1 Gen 1 interchangeable ??

    Yes an Alpha one gen one will swap with a MC1 drive. Should be plug and play. Also the alpha drives will be about 10 + years newer than your MC1 drive The driveshaft comment you are hearing is related to inline engines used a shorter driveshaft where it engages the coupler. Shouldnt be an issue...

PO cracked the block, i swapped in a 5.0 which by the factory would have come with a 1.62 ratio drive. Went from a 19”...
