60/40 Yamaha jet to 90/65 Yamaha jet

[BUSHRVN]

I'm looking for anyone who has done this swap/upgrade on their out board jet boat. I have an Explorer Industries 162 with the 60/40 Yamaha jet and I'm planning on upgrading to the 90/65 Yamaha jet due to wanting to get on step a little quicker and have a little more jamb pulling tubes etc. with the kids.
I do not want to change to a bigger boat etc., just a power upgrade due to the fact that I haul this boat up on top of my truck so that I can take it into BC along with my toyhauler bumper pull RV. So don't suggest a different boat.
I'm hoping someone here has done this swap and tell me of real world experiences with the performance differences this will make. Dave at Explorer Industries says that it will make a significant difference but also suggested talking to actual owners for a more in dept actual use testimony on it.
Anyone here done this swap or close to it?
Thanks in advance.
