Thanks achris


I have a Mercury Marine 4 cyl. Serial # 6854083 or 68540B3. was a little hard to make out whether it was a 8 or B.

Thanks achris

I have a Mercury Marine 4 cyl. Serial # 6854083.

That serial number is for a 1985, 120hp, GM 2.5l. (it's an 8, not a B)

Here's the genuine manual for it -> Service manual #10

Re: do it yourselfer

just a question to see if i got this right. I believe I have a mercury 2 barrel carb . the numbers I have on it are 13899562 and the 2nd number is 8Z03. If I read this right I have a mercury 2 barrel carburetor that is from December 03, 1988. If I did this wrong can you elaborate on it.

Did you try pulling the engine forward off the shaft?

Re: do it yourselfer

wasn't sure you could do this with the shaft stuck in there.

Re: sterndrive shaft stuck in engine

At this point in time you don't know if the shaft it stuck in the engine coupler or the gimbal bearing. Removing the side mounts and pulling the engine forward to let you know where it's stuck. If it's in the coupler you won't be able to pull the engine forward, in which case you'll need to get in there with a cutting torch and cut the shaft, then replace the coupler and shaft. If the engine comes out, then belt the end of the shaft and drive the gimbal bearing out with it. Then replace the gimbal bearing and (if you can't get the shaft out clean) a new shaft....

You guys are making me hungry with all these steak dinners floating around.

A fabricated puller with fine threads will pop that thing right out.

Start a new thread over in the Restoration and Hull repair forum. Stringers and Transoms are a very common repair in that forum.
