1990 Switzer 250SS Resto-mod
 
Back in 2016 I got a smoking deal on a 1990 Switzer 250ss. Everything was original and in great shape, including the interior. While overall it seems like a solid, well-built boat, the fit and finish is definitely lacking in a few areas. There is far too much carpet in areas that get wet, the windscreen and cabin door rattle over waves and the wiring behind the dash makes me sick. So now that my boat has been paid off for a few years I think it's time to start improving in some of these areas and make the boat fit my needs better. This will by no means be a quick process but I figure a build thread might help to keep me motivated and finish this in a timely manner. My plans for change include:
- lower fiberglass windscreen
- new cuddy bulkheads/center cuddy entrance
- remove stainless railings (bow, stern, windscreen)
- change dashboard
- clean up wiring/new switches
- new deck hardware
- build/upholster seating

some new foam with the old cushions, again for fitment purposes and not because im a child who cant wait to see how they turn out :)

haves0090 09-24-2023 02:44 PM

interior upholstery work will take a backseat till the weather is too cold to work outside. my goal for this week is to get the bulkhead panels tabbed in and the cuddy dash cutout filled.

always like the lines of the Switzer 250. looking forward to following ur progress. how does the boat handle at speed?

Boat handles really well at speed. Rides nice and level. But then again it only tops out at 60 in ideal conditions lol

Bulkheads glued in with thickened resin. Letting the fillets set up and then I'll come back over to layup the tabbing.

it still looked pretty clean before the resto!

Thanks! It was actually super clean prior to this undertaking. The vinyl was starting to show some signs of wear but other than that it's in great shape. I guess it would technically be more of a "mod" than a "resto-mod".

popped the panel this morning to fill the cuddy opening in the dash. Was hoping to get the bulkheads tabbed in today but the day got away from me. Everything prepped and ready to go for the morning though.

Twin O/B Sonic 10-01-2023 06:34 PM

Way cool project!

Always liked the looks of those boats and am a big fan of that size rig.

Owned/restored two twin OB 24’ Sonics and currently own a 25’ Checkmate IO that I converted to twin OB,’s.

See a theme 😉

A huge fan of……., see what it is, make it what you want.

Great job on the glass engineering.

24/25’ is way too small to have a cabin door anywhere but in the center.

Thanks! I am very familiar with your work/build threads!!! I'd love to hang an outboard on the back of mine though it won't be happening till the 400r's come down in price a little (a lot) lol

Twin O/B Sonic 10-06-2023 08:43 AM

Is that Nidacore?

Not sure how you laid up the bulkheads but a trick is to use an old glass patio door to lay up flat pcs.

I use one all the time.

J-Bonz 10-07-2023 11:22 AM

Great thread! Ready to see more!

haves0090 10-08-2023 10:17 PM

This is carboncore brand. It was much cheaper to ship than nidacore would have been. I laid them up on a sheet of melamine. Worked out great!

haves0090 10-30-2023 09:21 PM

Got the cabin entry dash filler panel glued into place this weekend. Seems like it's probably the last of nice warm weather for the season. I'll have to wait till spring to grind out and bevel the joint to tab it in permanently. I don't want to risk getting a bad cure.https://cimg2.ibsrv.net/gimg/www.off...323078413a.jpg

Yeah, I live in Ohio and our weather just changed to where I have to plan my projects requiring heat to cure.

I the boats inside, you can do a lot w/a space heater and a tent built over that portion of project.

Huge fire risk if left unattended but so far so good.

Unfortunately I don't have indoor storage for my boat. Looks like I'm stuck doing layups in my garage till May or so. It looks like last was probably the last of our weather above 60⁰. The challenges of living North! 😂😂

haves0090 10-31-2023 06:20 PM

Got over to the boat today to retrieve all my tools, clean up and check out my work. It's really solid even without being fully glassed in. Can't wait till Spring so I can finish up the glass work!
https://cimg6.ibsrv.net/gimg/www.off...7e82a4ba15.jpg

Twin O/B Sonic 11-01-2023 04:23 AM

Yep.

I’ve got a bunch of parts to paint and kicking myself for not doing it before the weather turned.

Im lucky and have a heated shop but it ain’t cheap to keep it at 70* for 24 hrs to cure paint/glass when it’s 20 outside!

I even use the tent/space heater trick inside so I don’t have to super heat the whole shop.

Your boats going to be a really nice, one off when done.

That’s a fun stage where your mock ups start to grown their own legs and you can see light just begging to come into view in the far end of the tunnel.

Got all the edges wrapped up in 2 layers of 1708. 1st layer on port and starboard side dash covers the whole backside and wraps up over the front edge.
https://cimg5.ibsrv.net/gimg/www.off...582bc5bd77.jpg
Got some sanding done. The tabbed-in filler panel is pretty close to flush.
https://cimg7.ibsrv.net/gimg/www.off...04b472727b.jpg
Got a couple edges sanded up pretty good. Only a few hundred more hours of sanding to go.
https://cimg2.ibsrv.net/gimg/www.off...3bd7bbdac2.jpg
Really happy with how everything is coming together thus far. I don't think I'll have all the layups done in time for winter because the temps are dropping quickly and my heat lamps can only do so much! I have plenty of sanding I can do to stay warm though 😂

https://cimg8.ibsrv.net/gimg/www.off...63684be3e3.jpg
Laid up some CSM in the low spots on the dash so I don't have to use much filler. All my low spots are less than 1/8" though, which was both surprising and relieving.
https://cimg9.ibsrv.net/gimg/www.off...6a8dff38a7.jpg
Needed to glass in a little extension here so that my cabin door seals better when installed. I guess my bulkhead panels weren't lined up 100% with one another. Why did I ever assume that the factory panels were square to one another? Lol
