Ranger seat post style

Just bought a used Ranger (2015 621 FS).

What “style” are the seat posts/pedestals considered?

Boat has 4 seats but I also want to get a power pedestal with a butt seat for up front.

THANKS for any feedback

I know this is an older post, you’ve probably figured it out by now, but I’m in the process of buying a butt seat for the bow on my 1860VS, it seems most of them use the Springfield base with the 1 3/4 inch fitting, found mine on Amazon and I also ordered the Millennium casting/butt seat.

Thanks, I appreciate it. That’s about what I came up with.

It’s been astounding as to how poor the local Ranger dealer is at answering ANY questions.

it’s a Springfield Spring-Lock. 1.77″

– front and rear deck are Spring-Lock standard bases/posts
– rear seats in cockpit are Spring-Lock with locking bases/posts (these have a detent in the bottom of the post and a matching bump out in the cylinder hole in the base)

THANKS! for the feedback.

So far not real impressed being a new Ranger owner (New owner, used boat), hard to get questions answered, with a significant exception, Pamps in Green Bay (5 hours from me) has been GREAT to deal with.

Local guys, not so much.
