Q1: where can replacement gaskets for the cup holders on a 190 OUTRAGE be purchased?

The cup holders on my previous Boston Whalers did not have cup holder gaskets. They were held in place by a sealant, possibly a silicon sealant.

On the 2019 190 Outrage there seems to be some gaskets. It's nice to be able to remove them for access and cleaning, so I am not too keen on using sealant.

Are the cup holders held in place by screws or some other mounting hardware?

No, just the pressure fit.

Any OEM part for a recently-made Boston Whaler boat can be purchased from an authorized Boston Whaler dealer who is actually interested in providing service to customers who want to buy a part.

With the Outrage 190 no longer in production, I doubt the cup holder gasket is available from Whaler.

I would investigate a gasket vendor.

It may be you will need to purchase gasket material of the appropriate thickness and cut the shape yourself.
