    2000 Alpha One Gen 2, U-Joint Knocking

    Try an oem gimbal bearing. Turn the input shaft in the drive possible that bearing on drive yolk is bad. the fact that you didnt have a knocking before bearing was replaced would make me think the bearing is bad or not seated fully

    2000 Mercruiser 5.0 Thunderbolt 5 Ignition idle issue.

    Maybe. Adjusting the notches on the choke element only makes it stay closed longer, so it gives it more time to warm up to operating temp. is the thermostat working and the engine warming up to proper operating temp?

    Merc 5.7 hydraulic lifter enigma

    I would use a crankcase flush in it like seafoam - put an oz per qt or L of oil in crank case and let it run a bit. I have cleaned up the varnish in older engines that were not well cared for oil change wise. Might have to do this a couple of times. I think I have seen some use seafoam spray or...

    2000 Mercruiser 5.0 Thunderbolt 5 Ignition idle issue.

    Adjust the choke as AD lays out , but if it stalls in colder temps when engine is warm you may to turn the idle mixture (not idle speed) screw out and fatten up the mix a hair. In colder conditions and warming up need a richer mixture. Can look at your spark plugs to see if they look white/lean...

    Solas stainless 4 blades all the same?

    Agreed I started with a pair of Michigan Vortex 4 Blades on my old boat (sea ray 170/3.0l) for more azz when towing skiers. Al was a good way to cut my teeth on prop swaps. My new boat I get bets holeshot with a Vensura but a lot of slip at WOT. The Revolution 4 I bought used on Ebay for $300...

    Solas stainless 4 blades all the same?

    I have both of these props and the nemesis is not a AL copy of a Revolution 4 no comparison between the two in performance... or cost. I was really disappointed with the nemesis/spitfire when i tried it insane amount of slip. Your point that it will likely be better than a black diamond is...

    Throttle spring on 1981 Mercruiser 120. Courting disaster

    post a picture of what you have. Some of the Mercs use throttle return springs in case the cable breaks but most do not. here is an example in a cut sheet of a 357 alpha. But it should close the throttle not open it To to mercruiser parts .com or marine engine .com and put your serial number...

    Another prop slipping thread

    Yes if you looked at the dog teeth they are back cut so under load from the prop it cant pop out of gear… and this is why they use the shift interrupt system. at least you have narrowed it down to the coupler. was the alignment ok when you took it off ? You don’t rally have to fully remove the...
