How much horsepower does my Seadoo have?

I just bought it and I am wondering about the horsepower of it. It is a 2004 GTX 4Tec Wakeboard edition. I'm just slightly confused because the owners manual says its supercharged but I can't find any info online about a supercharged GTX wake edition.|||If yours is supercharged it will say on decals. SC models are215 hp. Non SC are 155
