    2007 Mercruiser (4.3) Stern Drive

    Moog 344 or equivalent should work for external clip engine. Spicer makes a cross ref to it 5-3214X if you want a different brand. I have used moog 315G on my gen one alpha no issues. I bought a set of the spicers a year ago when I did my bellows but they were in good shape so I left the...

    Ticking/clicking noise Mercruiser alpha one 2002

    Its compression related willing to bet manifold to head, could be loose plug. Wouldn't think you are screwed but need to get in around manifold and head and see where it is coming from. Also wouldn't hurt to do compression check to rule out head gasket. Did it over heat ?

    Solas stainless 4 blades all the same?

    I found the slip on the nemisis/spitfire to be very high too. I think mine was over 20% . You may want to check your dash tach vs a shop tach. You may be reading higher than the engine actually is if the rev limiter is not kicking in. Surprised you cant trim up without porposing

    Oil pressure dropping

    Might be worth running a mechanical gauge while on water to verify. I would verify the wot rpm with MM. Forgot about break in. I didn't start running synthetic until after 100 hrs on the engine.

    Oil pressure dropping

    I have had some similar instances like this. I also am running a then new 5.0 base engine from MM. I found I would get this when running higher rpm (above 4k close to WOT rpm limit) for a decent period of time like going at WOT RPM for 10 plus minutes. Normally at high rpm my oil pressure would...

    YEs no advantage to the delco vs TBV except when you need to replace the module. this parts breakdown that may or may not be for your exact engine shows dist bushings. You can put in your serial number to get an exact fit . I would take the cap off and check the rotor for side to side play...

    2007 Merc 5.0 TKS stalled at speed, had to be towed

    Yes the warning alarm switch just disconnect the wire. This switch just creates a connection to ground for the horn. the fuel pump switch you need to jumper out to bypass

    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...
