    Confused with 5.7L Timing Cover Replacement

    Looks carbed (?) with v belts, so everything swapped over from the old motor likely. AD, was there a CPS on the 97 EFI? You'd want the composite cover, maybe post pics of the gasket difference. Also wondering if you have vortec heads, which would be another upgrade. Also, what are those loose...

    Pasty oil coming out the valve covers

    Ok, I'll grudgingly admit that it exists for a Volvo, although the bulletin didn't come out until 8 years after the vortec. And Merc as far as I know never put one out. Even with removing the drain, the important part is probably lowering the bow of the boat. And even if you don't do that, the...

    Gimbal bearing.

    Yeah, but it's one of those things that you can't inspect until you split the drive. At that point I just replace it. The gen 2's are supposedly more durable anyways.

    Missing 3.7L Alpha One Gen 1 Water Shutter Valve

    Don't know if your overheat is the cause or effect of your shutters burning up. Love the guide, I'm going to save it. Saw you put part numbers in some places, as well as torques. I'd love to have a list of common torque values that I can never remember (outdrive, prop, steering pin nut, etc) in...

    Trim not going up with switch on shifter

    It's normal, and it's a malfunction. At least it's common. No need to fix unless you want to. Can jumper if you want like scott06 said or just use the trailer button.

    Mercruiser 3.7 MCM 165 not getting to operating RPM

    Only if the drive ratio/prop pitch is different. Could have some fluctuation in RPM with a different prop of the same pitch, but not 800 rpm. Could have broken something in the engine if the drive seized suddenly. Check compression like @Scott Danforth said.

    Gimbal bearing.

    Yes Certainly valid. Don't know how often the bellows fail without warning--I inspect mine fairly frequently. Replaced with OEM when I first got the boat since I think they were likely 20+ years original (remember talking with a smug dealer who was convinced that it was beyond the abilities of...

    Pasty oil coming out the valve covers

    Nothing Still does. You gotta find me that service bulletin or else it doesn't exist 😉

    Gimbal bearing.

    I'm in the minority having run Sierra rubber bits without issue. Seems something else always breaks first, and I'm replacing the rubber before it wears out anyways. Last bellows are 4 years in and look brand new

    2004 Merc TKS intermittently missing, running rich, running on.

    See if you actually are dropping a cylinder. Put a timing light on each plug wire when it's acting up, see if you're getting consistent spark. Don't think that would cause the dieseling though.

    Engine cranking with ignition switch off

    You should only have voltage when the ignition is on

    Engine cranking with ignition switch off

    Maybe give us a hint as to which wire you're trying to connect? In general you're getting a short to power on the yellow/red wire... Is this a TKS?

    Filling coolant reservoir 3.0 TKS?

    How many cc 3.0's are out there?

    Bellow Replacement

    I have a regular socket that I use. Really only issue is getting the old one off, and if you cut the cable then a normal socket bites well.

    Bellow Replacement

    I have a tube on mine, didn't notice a difference in noise.

    1997 Mercruiser 5.7l w/ 2 barrel carb & thunderbolt ignition

    Yeah, knew about that one. We need a, "Well, you didn't read that last sticky and already bought the boat, now what?" thread.

    Mercruiser 3.0 No Spark issues

    No, but it's the same thread.

    spring vapor lock?

    Probably. Hard to say without hearing it. You need to actually go to the engine compartment and listen to where it's coming from It could do either, but unless you're either cranking the engine or the ignition is in the on position, the switch has no power going to it

    Need help locating serpentine belt part number

    Whoa! $75 for the cheap one. Must be made of precious merc-nesium.

    Mercruiser 3.0 No Spark issues

    Yes, your earlier posts suggested that it leaked on muffs, which wouldn't be the trim manifold I use a piece of hose with a schrader valve clamped on one end and a gear oil fitting on the other. Use a bike pump and gauge to measure. Plenty of fancy ideas if you search on here, but mine works.
