Mercruiser Trim Limit and Trim Sender Kit

[TomNJ]

I need to replace the Trim Limit and Trim Sender Kit on an Alpha 1. I can not figure out how to get the wires through the stern drive. Has anyone ever done this.

Re: Mercruiser Trim Limit and Trim Sender Kit

Much harder that it should be

You have to pull the whole thing apart

remove drive

remove bellhouseing

Put in wires

Put everything back toghter

Thanks. How do you guys find this stuff?

I replaced the entire transom assembly on my boat when I rebuilt the transom. And even with the assembly sitting on the bench in my shop it was tricky getting to the bolt that holds the wire retainer up in the top of the assembly. It is definitely a job which requires patience. (Small hands help too!)

I know this is the wrong way to do it, but I was not going to rip it apart. I just cut the wires from the old ones and soldered the new ones on with bare butt connectors and shrink wrapped them with a touch of grease. The boat has been in the water since april and I haven't had a problem yet. It wasn't worth it to me to rip everything apart, but you may want to.

That would cause a BIG problem in a saltwater boat and could cause galvinic dammage to any boat

I just By-passed the limit switch at the bullet connectors,+ drive by the Seat of my Pants,......d

Bondo. My TL switch wires were cut and finally failed. I wondered why all the corrosion started showing up and now I know. I plan on replacing it this winter. Do you really need to run the exhaust bellows on a thru transom exhaust alpha 1?

Re: Mercruiser Trim Limit and Trim Sender Kit

I just replaced mine when I had to replace my lower shift cable. While I was in there I also replaced my bellows (now I get almost no water in the boat... for years there was always a decent amount when I pulled the plug).

So, I would strongly suggest doing more things than just the switch if you go in there....

Rest assured that it will get a new u-joint bellows. I just don't want to fool with the exhaust bellows if it's not necessary.

I picked up an old '79 that could use new tilt/trim sender units. Got the kit BEFORE I looked in depth and realized they now want you to take apart the whole transom to replace these. I'm thinking of following ripped_78's lead and wire the new senders to the old wires. Thinking I'd be better off encasing the connection in silicone rather than shrink wrap and grease. This is a non-salt water boat used less than 50 hours a year that will sit out of the water on a lift when not being used. Any thoughts or experience with this shortcut tilt/trim sender replacement approach?

If you have a question, it's best to start a new thread, you can use a link to this post for reference, but in no time your question will be lost and many people only answer the first question anyway, and never read the other answwers.

I always did this on all my old boats with an I/O, not one had a salvagable trim switch, or wires! You can learn to listen to change of pitch of the trim motor sound, and adjust accordingly, But yes if you can splice the wires, & make them water, & corrosion proof, it should be fine.

Yes, A nightmare of a job to replace or rewire!

Re: Mercruiser Trim Limit and Trim Sender Kit

That job is a *** well difficult at best. It is best done when servicing shift cable, bellows, water hose,etc. My merc rep told me many years ago to replace the clamp with the one used on the Gen 2 drives. Only uses the bottom screw, but it is also twice as thick, so do not just leave out the top screw, Remember that seals the big bad blue from our boat. Part number for that clamp 54-12078. hope this helps, Bill
