I see the 2020 19 is now offered as 190 with standard 180HO and now a 195 with a 180 w/supercharger. Boat test stated a top speed of 48mph but I noted other videos claiming low 50,s. My guess is the upper 40,s is a bit more realistic.
 
My understanding once they extended the haul length a few inches in 2019 on the 19 footers, the added weight dropped the top speed from 52-53 mph's to 47-48 mph.
 
I wonder how stupid it would be to add a supercharger to mine.

To work well it would need to be the entire drive train with the engine/SC, ECU, but also the shaft and pump assembly/impeller - all different in SVHOs. It would easily be 20k-ish.
After that - your range could be a bit of an issue, even the 190 N/A the range is not so great.

How much horsepower do the SVHO engines put out? I know the HO engines are ~180, but haven’t heard anything about the supercharged ones.

260hp(?) I think.
They spin a larger pump/impeller, too (160 vs 155mm).
 
Also, they need to burn premium fuel too.
 
I can't answer for the FSH model, but my 2020 195S with supercharger has reached 48 according to conext screen
 
We run full out in our jet boats. Most of the time other boats do not, so if a boat has a top speed of 60, most of the time it will cruise at 38 or 40.
so 48 for a center console and just running full out all the time is fine I think. I run mine at 40 a lot and am always passing boats. I can’t Evan think of the last time a non speed boat passed me.
