Seadoos reverse steering is the opposite of Yamaha and normal boats. You can do the same manuever in a seadoo boat as well, only difference is that when you switched to neutral from reverse, IF you had your wheel to one side you would then need to move the steering wheel to the opposite side.
Personally haven driven both seadoo and yamaha, I MUCH prefer SeaDoo's fixed reverse gate setup over Yamaha's swivelling gate. Yamaha reverse is almost worthless. Especially trying to really really steer in reverse. Yes, I can do some stuff, but it's very limited. You can't do a figure 8 in reverse (not that I want too), but it shows how limited Yamaha reverse is, at least on my 07 230. Seadoo's reverse is very very effective because the fixed reverse gate redirects the thrust out to the side. As a plus, the same design also allows seadoo's to truly spin in place on a dime. Our yamaha's also spin in place, but there is some slight fwd creeping. Also Seadoo's can spin MUCH faster in place.
I reverse off with the steering wheel straight. Once I feel I'm clear of the trailer, I move to neutral, crank the wheel over, spin, straighten out, put in fwd. Now if it's a very long dock and it's too narrow to spin inbetween, or there are other boats tied up and I just don't have room to spin, I get nervous if I have to reverse a long distance. There were times I couldn't do the reverse,spin,fwd trick with the seadoo and I did have to reverse the whole way out. In the seadoo it was easy. I hate doing it in our Yamaha.
