Also fits SN 200 2019+

Systems: Random no starts, neutral lock out not working.

I found next to nothing out there when it comes to this replacement procedure.
I would like to give special credit to aerojust for taking the time to post the procedure on his thread, it gave me a great kickstart:

Nautique Parts, ordered new base on Monday, showed up at my door Wednesday afternoon (regular shipping). Good job NP, and thanks for the "PND" 10% discount code.



Things you may need.

Remove throttle center cap, it just pops out



3/16" Allen




Trim removal. Try to find a corner or area of easiest access. Once you've gotten the 1st tree to pop, just follow the path and try to get as close as possible to each tree with the tool(s). You have a few panels to pull...


Apparently, someone let Lucy have a sharpie at the factory, they should of known better.



Not much to the control pad, I was expecting more. Detach plug.


I would of loved to have been able to pull the seat cushion behind the drivers seat, better yet, I would love to know how?


A plethora of phillips screws surrounding the hard cover.


Man I've been wondering where those 2 bobby pins went, been looking for those for years.




A flexible extension, one of my top 10 tools, and it seems to get used on boats more than anywhere else.


Unplug base.



The red arrow on the right indicates a screw only, the other 3 have nuts. Reach in for a feel to see that yours is the same.


I went with a 10mm, but I think it's actually a 3/8". Didn't want to crawl back out of the boat.


Old base, dated 2016


New base, 2024


A like to throw a little dab of Dielectric Grease on the electrical connections


Assembly in reverse.
Word to the wise, remember to plug the safety lanyard back in before testing. I'll never get those 30 minutes back of what did I miss, fetch.
Neutral lock out works now, there is even a blue light on that thing, cool. All seems well on the test fire, we'll hit the water this evening for the final test.

I hope this deems useful in the future. With this outline, you should be able to tackle this in an hour, 2 people would be extremely helpful.

Great instructions.
Why'd you have to replace? Just for the neutral lock out?
I don't think my neutral lock out has ever worked.

[Scooter G]

Thanks Kmayotte, just wanted to save others the what do I do, where do I start.
For $550 bones, I could deal with the Neutral switch not working (also never worked).
We were having random no start issues. Press the green start and nothing would happen, move it in & out of gear, press button again, and again...
Got towed in a couple of years ago by a '74 Bayliner when the prop shaft sheared. Don't really want to have to repeat that process, but if we do, remind me to drain the bags next time, lol.

Kmayotte if your 2016 still has the original throttle base assembly, it not a matter of if it will go bad, it’s a question of when. When it does you won’t be able to start the boat as the TBA thinks the boat is in gear (when it’s not) and the “neutral safety switch” mechanism stops you from being able to start the boat. The neutral button not working is common indicator that the unit is going bad. It’s a known design issue that has been fixed, so once you replace it, your good…

if you search there are lots of threads about this on the site. My specific write up for the 200 I put on ballofspray about 3 years ago.

Good looking out thank you. Every problem I've had with my boat has been an electrical module that bricked the boat.

[moovalyaG23]

Thinking I might have same issue based on Scooters original thread and described symptoms… assuming there is no way to see an error code if computer thinks the boat is in gear?

Do the pics on this thread display for anyone else?

[SANonTellico]

No, the pics are not displayed.

[bturner]

Yeah, this is what happens when you use a link to the pictures on something like photo bucket. Too bad, looks like there was a bunch of good information there.

[Scooter G]

In my defense, that's what happens when a Forum doesn't get backed up and the site crashes all your thread pictures.
Not super happy about that little piece of trivia...

My neutral safety switch doesn’t work in my 2020 g23. Took the boat out the other day and it wouldn’t start t start and it eventually started randomly. Should I start with this?

[Scooter G]

Jeff (NautiqueJeff), any chance I could repost the pictures lost here?
I've tried everything I can think of, edit, redo, repost, stand on my head, the system won't take any of the JPG's. They will upload, but they won't post.
I was able to update the following thread, no problem.

Thanks

[Scooter G]

Never mind, I answered my own question.
Apparently, or at least in this situation the picture file extension needs to be in a ".JPEG" format, not ".JPG" (although .jpg is what was originally posted). Probably in the fine print that I missed somewhere.
All is well.

[Brichter14]

Thanks for updating the photos. I ordered a new throttle assembly today. Hopefully fixes my issue

[bturner]

Wow, great post when the pictures are there Scooter G. I don't think the interior is quite as complex on my 200. The more I think of this and the shorter my list of other spring projects seem to be getting as I knock them out, the more that OCD is kicking in. Which in turn means the more likely I am to actually buy the part and do this project. Having this excellent tutorial just adds to self imposed pressure to fix this. Hmmmm, going to have to give this some more thought before the boat comes home.

[Brichter14]

Did mine tonight. Wasn’t too bad except I was in the garage and kept hitting my head on the Bimini extension. Will say scooters walkthrough was great help. One thing is if you have a battery powered ratchet you can skip the step of taking the black plastic piece that holds the neutral safety switch and speaker completely out. Just put a Philips screwdriver bit in a 1/4” socket and tape it like pictured and then stick your 3/8” socket on the back of the throttle assembly and loosen it up. Also if you drop your wrench behind there you can get to it by unscrewing the stainless plate at the front of your seat bottom. ask me how I know this.
