Seats, this is one of those items that works for you or it doesn`t. Pretty much like having comfortable underwear, lol...
I was never really jiggy with the bolster/bucket type seats in the 98 SeaDoo Challenger 1800.
By todays standards the boat is not fast, and we don`t operate it like it`s the death race to the finish.:lol:
Although it can carve turns like it`s on rails and run over 50 mph, it`s more important to be able to maneuver in and out of the seat when the Shiba`s :dog:are aboard and comfort being the main objective on our backs.

after looking at several seats online and not actually having any aftermarket seats available to try in the boat, we chose the Attwood Centric II SAS seats bc of the suspension.

After receiving them, they do look like a well built seat. We have to wait for a bit before we get to try them out tho...:noidea:

to KISS (keep it simple stupid) I used off the shelf aluminum angle, aluminum sheet, and hardware from the shop and Mcmastercarr.
The swivel function is built into the seat buckets on the Doo, and that option wasn`t really necc. In the years I had the boat we`ve never rotated the front seats. So utilizing the factory sliders and adapting them to the new bolt pattern of the Attwood seats is the goal.

We also wanted a bit of recline to the seat as the Centric SAS is more upright than the OEM bolsters. To accomplish this, the angle was cut to the desired degree of recline, then fastened together with socket head bolts. There was also a very large 6 1/2 hole in the OEM seat slider, which was covered by a fabricated aluminum sheet and held in place with a few rivets in existing holes.

After the metal was cut up and assembly started, then prepped and painted, the adapters were mounted to the new seat bottom`s and then mounted to the modded OEM sliders.
The pictures will tell the rest of the story.
Thought I`d share a different take on seats other than factory bolsters in a SeaDoo jet boat.:cool:

BTW, the boat and trailer have had a total rehab from 2012 to present. ;)

The rear toilet bowl type seating is also getting swapped out for a traditional bench type seat. ;)

Re: 98 Challenger 1800 seat refit mod.

update:
I purchased a WISE 58" bench seat for the rear. made a mounting frame for it so I can easily attach the seat bottom to the hull.
I separated the seat back from the seat bottom and modified the hinges to mount the seat back to the firewall/hull so I can still have the fold down function.
