Super Jet hooker for a stock 650

[alberta guy]

I got a bone stock 650 SN. My question is can I swap out a 9/15 hooker from my other SN superjet to this one? Will I be over propped?

Everyone has told me the prop you want on a 650 superjet is a 9/15

Damn. I run a 9/15 hooker on my 771?

So will I be over propped or not because I don plan on putting a pipe on this ski.

It wont be over loaded because of the 650s low port timing. A stock 650 will only rev to the low 6000 rpm range, that is where a 9-15 will load it. A good 771 with a pipe will turn the same prop around 1200 rpm higher and make 40% more thrust.

So does that make Bruce skis square 40% better?
