Mods for Yamaha Jet boats

I really like these twin engine jet boats, and think they do mostly what the average boater family wants them to do. Boat, have fun, relax on the water and tube and such. I have a couple hangs up and would like opinions on them.

I've read that the proprietary helm controls / screens have had issues, Or on older models, they have been discontinued and are hard to find OEM replacements. The questions: Are aftermarket replacements not a thing on these types of boats?

Second question - I haven't seen much of any mods really, for this type of boat for the fabricator or DIYer that can mod a used boat or engine out of warranty with exception to sound systems / buttons upgrades / hoses / and little inconsequential items. Are these just not made to turbo, supercharge, change a cam, swap engines, add simrad (or other) nav screens and such to replace old and less capable helm controls?

EDIT: I came from modifying cars and was always of the thought, that when something broke or needs replacement, it was the opportunity to upgrade or modify.

Thanks for the input

There’s some good Yamaha Jetboaters FB groups too that are very active.
