    lower unit

    being duals is one counter rotation? I could be confusing things for you, but not sure on an alpha if the counter rotation is done in the lower. Edit - SEI makes a separate lower for CR -https://www.sterndrive.cc/product/Fits-Mercruiser-Gen-I-Lower-C-R-8951A33.html So if the cracked lower is...

    Upper and Lower Drain Plug Merc Sterndrive Alpha 1 Gen 1 Question

    Yes each one takes a gasket they sometimes can stick in the housing. I think the OEM merc ones are yellow now but they used to be blue fiber paper ones back in the day. without a gasket you will get water in the gear oil

    3.0 L mercruiser issue

    Probably have multiple things going on. When it dies and will not restart does it have spark? Check with inexpensive spark gap tester. Fuel tank vent could be plugged, fuel system is definitely contaminated likely tank lines and carb need to be cleaned, but I would think that would not allow...

    What oil should I use?

    Exactly my similar vintage 3.0 had same cap on valve cover but merc documentation recommended straight 30 w or 40 w depending on ambient temps

    Got a new toy to test out eventually...

    I got best results with a revolution 4 vs a Enertia. Enertia is a very good prop but might not be best for every application. Would think even with bottom of the V is in a good spot

    you can trim the annode with a grinder or get the flat one. Very common for props to hit them other than basic Black Max Al ones

    Does the antifreeze you use really matter?

    You are not wrong there are only 2 drain plugs on the 4 cylinder. IF you have power steering you may need to pop a hose off the PS cooler if it traps water. I'm not far south of you in upstate NY and do as mentioned - drain fully, I use about a gallon to splash back into the hoses to chase any...

    U-joint Bellows & Upper Shift Shaft Bushing

    Agreed that bushing and seal assy is pressed in the bellhousing lightly. On the bellows adhesive - only put it on the areas where the bellows and lip on transom housing fit together just a light coating on the lip around the gimbal bearing and inside of the bellows where it seals on the lip...

    I have a leak.

    Sounds doubtful at best. I would be looking that the bellows are not leaking depending on position of the drive L/R & Up/Dn , or there is another leak in the cooling system Have you looked at the driveshaft bellows closely ?

    Bellows Installation

    Yeah the newer style push on hoses are pretty cool, no clamps required . I use them a lot at work ( in larger sizes) to make air and water hoses on site with no end crimping tools.

    Mercruiser 4.3 Prop Question

    Also check the tach vs a shop tach. Would not think if you had soooo much pitch that wot was 3800 that you would have the great holeshot that you mentioned. either rpms are off or there is a tune up issue have you verified timing both intial and total? and what do the plugs look like

    Bravo 3 Refresh Questions

    Look closely at the corrosion a buddy of mine had to replace his lower housing as it cracked by bearing carrier due to corrosion. I think the later ones had two annodes on the cav plate vs the original single one. Ultimately he ended up putting a second mercathode system on it with transom...

    4.3 mercruiser vortec issue

    the push rod is moving ?? I understand the valve is closed but the pushrod should not be moving down unless the lifter is collapsed or lifter is not on the cam fully, or is the pushrod not seated against the lifter? Is this the same for all rockers? No milling the head for warpage would not...

    What oil should I use?

    Use the T4 conventional rotella . It has enough zinc for flat tapped cams And is an excellent value
