Thx both for the responses!
I have been skiing mostly behind a PS190 the past few years but also some behind a carbon pro. Preferring the carbon pro though. (both Club skiing).
I have recently moved to Denmark and don't have the option for perfect lake water everyday anymore :(
I was out with a friend a few times this year who owns a Glastron GT185 I/O. When making the boat as light as possible the wake was decent as 22 off only occasionally catching air. Putting just one or two persons more in the boat made it scary as hell at 22 and even with no one extra in the boat 15 off and 0 off was no fun.
Was hoping that the outboard would provide me with a much better wake. The NXT20 outboard does also look promising even though I have less data to go with, but at a price almost double the GTS180 it should be considerably better.
Last option is of course to go for a dedicated ski boat as 85% of the time it will be used for skiing, I am just not happy leaving it in saltwater for 6 month a year. Additionally I would have to import it as there is like 2 ski boats in Denmark, and almost none used are with saltwater packages ☹
