Custom/Hybrid Wb1 & rockered sj projects

[Justintimegtc]

Hey guys, just got back into jetskies this time around with Yamaha. Here is what I have and what I think is best and I am looking for some feedback.

I have a WB1 that is all stock except impeller and carb. This ski is already apart due to having to rebuild mid shaft and pump. I was going to put a west coast pipe on it but I threw a Superjet into the mix.

I have acquired a rockered shortened flat deck superjet. Bare hull. It is set up for surf riding.

I have a wave raider doner ski that everything works perfect.

What I'm thinking is putting the 701 in the superjet with a pipe. And putting the 760 in the blaster. It sounds like trying to figure out an exhaust for the 760 in the sj would be difficult but 701 will be easy drop in.

Can I get an aftermarket WB2 pipe and put on the 760 and drop that in the WB1.

Thanks in advance

Doubt you will get a WB2 pipe in a B1. I am running a 781 in my B1 with a FP limited chamber with no problems.

With that 781, is that a factory pipe for a 760? Or what exhaust manifold did you use? Setting up the exhaust seems to be the problem.

Just use a 62t manifold with no mod, or 61x and drill out the holes. You are good to go.
