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.

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.
