    Stupid Question from New Member

    This - had to chisel mine off. Your engine is the 153 ci/2.5 l which is the smaller brother to the current 3.0. The engine family is related to the 194/230/250 ci straight 6, and was first insatlled in the 62 chevy II. Your drive set up is likely the early EZ shift vs the newer MC-1 drive. Merc...

    '98 Stingray 190LX 4.3 Merc Stuck in Muck Issue

    What is super hot in terms of temp two thoughts not unusual for manifolds to be different temps due to not being level. Also since this thread started with sucking up silt could be clogged

    Sank the 'ol girl!?!

    Yeah I would pull the distributor cap and look for corrosion. Yes ignition module and sensor in distributor would likely get smoked if they went swimming The TBV ignition is fantastic until you need the module which is crazy money . I bought a spare on eBay years ago for $200 but don’t see...

    4.3 runs great for about 30 minutes then bogs, pops won't accelerate

    Try opening the fuel tank fill cap to see if the fuel tank is under vaccum due to a plugged vent. Did this start immediately when swapping the carb or were you having carb issues before swapping the carb? reving in neutral is relatively meaning less as the engine is not under load. Do you...

    4.3 mercruiser alpha 1

    Before you jank engine I would try pulling the drive to ensure that the drive, gimbal or u joints aren't locked up. Then use a strap wrench on balancer so you don't risk breaking the balancer bolt off in the crank.

    Assembling exhaust manifolds, risers and elbows - Loctite 510?

    bondo is saying put the gaskets on dry , use the perfect seal on the bolt threads. Perfect seal seems to be a magic potion keeping the threads from corroding so you can get them apart next time ….

    Are you getting clean gas to the carb and a strong spark? Was fuel filter changed ? Might be water in the line. Dribble gas down carb someone cranks it should be able to keep it running if u have spark wnd fuel contamination is the issue

    4.3 mercruiser alpha 1

    As mentioned another 4.3 is simplest. Not sure what boat this is in And if a V8 would fit in enginecompartment I swapped a 4.3 for a V8 in my 21 ft sea ray. It was easy because the boat was offered with a V8 from factory, so engine mount stringers were big enough to accommodate the mounts...

    4.3 mercruiser alpha 1

    Might pull the drive - if there was water in bellows gimbal or ujoints may be frozen as well.

    Gimball ???

    Definitely first place to look is gimbal bearing and ujoints. If water is in there probably both are an issue Can it wait hard to tell from my keyboard. Never let one go that far to locking up .

    Shift interrupt switch - how to adjust??

    Yes should take little effort like shift with two fingers. if it is hanging up jank drive and see if it is cable (likely) or shift rod and swivel shaft in bellhousing. Can get junk where the shaft slide is

    Mercruiser Alpha 1 Gen II leaking above speedo hose

    That hole goes into the exhaust passage which is has the cooling water that is dumped overboard (exhaust is open to water on prop end) . The clip on the hose for the speedo is supposed to go in there, likely it was broken off at some point.
