Alpha 1 Gen 1 shift adjustment

[Speeddemon007]

Hello, new here, and I've searched around, but can't find the answer to this specific question.

Had my new to me, 21' Thompson Cuddy, with 3.7L 180, and alpha 1 gen 1 out last weekend. Maiden voyage started out great.

Left the wives and kids on the dock, while my buddy and I went for the first ride on the lake, in case any issues came up.
Issue that arose, we fixed (somewhat) but I feel needs further adjusting.

Everything was working perfect, until it wasnt. The shift cable on top of the motor, has a brass barrel adjuster, but also has a locknut against another barrel adjuster. That locknut came loose, and I lost forward, in fact, all the way forward, was reverse, and reverse was reverse.

We adjusted it, so it engaged again, and had a great rest of the day. However, forward doesn't have a solid "click" into gear. Picture hitting the gas in a CVT transmission, you're just suddenly in first and moving, with no shift noise. Same with reverse.

Now, is there a proper measurement/setting for that rear barrel adjuster with the locknut.

Sorry for the long winded post, just figured I'd give some solid info on what happened.

It sounds like you need to invest in a service manual for your motor and outdrive. They take a fair amount of maintenance.

Agreed, I have the abilities to work on things, if I have the proper procedures in front of me.
There are a bunch of YouTube videos, explaining how to setup the shift cables properly, just none of them adjust the barrel that came loose on my unit. Only the main brass barrel.

You could repost this in the MerCruiser forum. Those guys will probably know. I cannot remember the shift linkage well enough to assist you. Post a picture if you can.....
