What do you mean by upgrade?
If you mean doing mods then yes I will but I've had a look and can't really find anything for a GTX 155, if nothing is available then I guess I'll hold on to it for a couple of seasons and then sell for a 3seat performance model.
I went with the 155 as I know it needs a lot less maintenance in comparison to models with superchargers which I figured would be a good move for a first ski
Welcome. It’s always good to start slow as you did with a good reliable model to make sure you like the sport. Just be careful as collecting Seadoo’s can become an addiction.
