Does anybody have fin settings and binding location for a 67" C1 ?

Was he on a 2024 Vapor Pro?

spot on!!!!!!!

@mlangeI don't know if your engine has knock sensors but my 5.7 pcm 2009 nautique 196 does and after going thru pretty much what you have I discovered that I needed a new knock sensor and that cured the surge problem' I  have 2 knock sensors one on each side of the engine block. You have to remove them to drain the engine block. You have to make sure that the single wire lead going into each one is plugged in properly. Hope this helps.

@ColeGiacopuzziSo what would you recommend for a 67" 2023 Senate Pro? Shallow and long also?

@ColeGiacopuzzi Well Cole you are on a roll!

My friend has a 2023 68" Vapor Pro. RFF skier. Where should he start with his fin and binding location?  34 mph skier with Reflex front binding.

@ColeGiacopuzzi You were spot with those fin settings for the Senate Pro. What a difference moving from deeper 2.485 shorter 6.865 to the shallower longer. it  really freed the ski up.

I have one more question. I use a T factor front boot and the heel is very similar to the Radar  front boot heel. Should I measure the binding placement from the heel(plastic) of the front boot to the tail of the ski or the heel rubber? I think that if you are using Radar boots it is the heel(plasticc) of the front boot.

@ColeGiacopuzzi can  you give me short and deep fin settings for a 69" 2022 Senate Pro and binding location. Currently skiing at 34 mph.
