    Has anyone ever seen this weird oil sludge under valve covers? Any ideas?

    Well, this thread was originally about sludge inside an engine. Having oily sludge in your bilge is a totally different issue. It is possibly just a simple oil leak from your engine into the bilge.

    That looks like a picture of your bilge.

    What in the world is this?

    I only discovered that the tube was facing the other direction recently. Now that it’s all installed, it it would be a lot of work to open it up and change it. I am going to mock up the engine bell housing and shift plate to see if there is any kind of interference. Yeah, I’m thinking I will...

    What in the world is this?

    Yes. that bushing goes inside the fitting to seal the tube in the gimbal housing. I actually ordered one thinking that it might be what I was looking at, but it’s not. I think for now I will accept your diagnosis that that is the end of a hose that has been cut off. It is definitely not...

    What in the world is this?

    It never occurred to me that this was the old hose. It looks for all the world like a bushing. It’s got Stainless Marine manifolds, t-stat housing and crossover. Been on the boat for years (these parts have outlasted two engines) and work okay.

    What in the world is this?

    Really? I don’t see it in the parts lists. Maybe I’m looking in the wrong place.

    What in the world is this?

    I’m assuming this was somebody’s bright idea, and not an actual mercruiser part. I actually like the idea, since I can use one size water hose for everything (I have aftermarket cooling system hardware and this would allow for using 1-1/4” hose for all of the supply lines). What do you folks...

    Which way does the gimbal seal face

    Correction. After checking back over everything, the problem is in engine output shaft yoke. Only one of the cups slips.

    Which way does the gimbal seal face

    I’ve been looking into it some. There are lots of ideas out there on how to manage the issue. Lots of people suggest loktite and other methods. The lower unit input shaft is new. It’s the center yoke that has the slop. Being a cheapskate, I’m considering alternatives to replacement.

    Which way does the gimbal seal face

    I’m using greasable u joints also. Related question - when I installed my new joints, I noticed some of the cups are just slip fit in the yoke bore. The clips of course keep things in place but are these supposed to be interference fit?

    That time of year again ...

    I’d suggest a remanufactured long block. Being a cheapskate, I have done this using automotive suppliers rather that marine. Verify that they use stainless steel head gaskets and brass freeze plugs. Or just change them out yourself.

    And yes, possibly exhaust manifold failure. That usually takes a while to show up, because the water ingestion will be slower.

    Has anyone ever seen this weird oil sludge under valve covers? Any ideas?

    It’s water. No question. It’s either 1) cracked block or head, 2) blown head gasket, 3) cracked water passage in intake manifold, 4) failed intake man gasket. Those are pretty much the only places where there is an interface between the cooling system and the crank case. I suppose if you have an...

    Alpha style shift cable bellows help

    Greetings collective brain trust. I’m preparing to install a new lower shift cable, and just wondering if any of you have a favorite instructional video or any particular tips to make this task easier. The particular task I’m hoping for help with is the bellows installation. I don’t know why it...

    Questions about exhaust system features

    But in my mind the logic of that seems flawed, given the size and location of the ports. They usually sit below the waterline (I realize not very far, so there’s not much back pressure), and they just seem too small to provide much relief.
