pieces of something when taking lower unit off

[DuKn]

Bayliner Capri 1850 Mercruiser 4.3l Alpha one gen 2
Was taking the lower unit off to replace the impeller and i noticed 3 piece of what looks like a rock and 1 piece of aluminum casting from somewhere.

The large donut shaped piece looks like the seal setting tool that was not supposed to be left in the drive. Not sure about the others.

not good news?

It's only used to slide the seal down the shaft onto the impeller housing. It's intended to set the seal evenly all around rather than doing it with your fingers. Then you remove it and toss in the trash.

Yeah i see now, my kit didn’t come with a new seal and the old one was tore and fell out probably due to that slide tool. I order a new seal and i’ll just reuse the tool.

Check the exhaust shutters too

might be where the casting is from. The other thing the slinger on drive shaft on top of water pump housing

 

[Stinnett21]

I was thinking shutters to but I don't think the metal in them is near that thick. The casting piece is puzzling. DuKn, look up into the driveshaft housing and see if there's damage anywhere.

think I i found it when I pulled the upper drive to inspect the bellows

 

[Stinnett21]

Ugh yes you found it.

Damn. Thats one I haven't seen. Only good thing is it's in a location where water can get in and not be an issue though I'd be curious what caused it.

I am so lucky to only run in clear fresh river and lake waters. My 2 old Evinrudes look spotless in the coolant passages.

True, i’m the third owner, so no telling how it happened.

Shouldn’t hurt nothing right? If so i do have a spare out drive i got for $200.

Personally I’ve only ran it in lakes, but i’m also the third owner so no telling what it’s been threw.

 

[Stinnett21]

Probably got a piece of debris caught in there and damage occurred while trimming down onto it. Any damage to exhaust bellows?

is the rest of the bellhousing structurally ok? crack doesnt travel? the exhaust passage is full of water at rest anyways. if you have it off to do bellows you could have it welded back in

I will take a look next time i’m off, still have the whole outdrive off getting new ujoints put on.
