I have a b1 hull I just picked up and have my eye on a couple donors with 760's how well do they pair.
What changes need to be made mainly exhaust?

Hi, I actually had a ski that had this setup. It had a waveraider 760 with stock exhaust and electronics. I didn't feel anymore low end power than the stock motor (although my friends did) but top speed was noticeably higher. I agree with the rest of the users, change the pipe to an after market one to get it to run even better. I think you have to use the 701 head to mount the stock exhaust. 760 head apparently has a different bolt pattern. That's what I did.

How was the fuel consumption with 44's compared to the 701? How does the 701 head work on 760, do you just use a 760 head gasket?

The fuel consumption was pretty good and the ski actually surprised me with how far I could go and come back on a single tank. The trip I took was longer than the trip my friends could make on their superjets on a single tank. That said, the 701 probably had better fuel consumption. I believe that the 701 head gasket was used but I'm not sure. The 701 head worked well but I couldn't shake the feeling that the engine was being restricted. I didn't feel it performance wise but the idea of a 701 head with a stock exhaust on a 760 engine kept me thinking about how fast and powerful it would be with the correct parts and an aftermarket exhaust.

I put a 760 B2 motor in my B1 after i blew up the 1100 that I had in it. The 760 has more top end than a 701. I ride surf and installed a b-pipe on the 760. I love this set-up this is what should have come in the B1. I added dual 38's instead of the 44s.

Any chance you would know the jetting you were using In the 38's?
