Got some 34 4 blades, used for squirting around the small lake here, vibrate the boat pretty good, is this a balance or cup issue? The 5 blade 41's are smooth as silk.....
I have access to a dynamic balancer, anyone do this themselves?

Shawn our 4 blades did the same right out the box, and the 5s run smooth as silk ... should try a set of 3 blades if you wanna feel some Vibration




ROCK ON !!!!!!!!!!!!!!!!!!!!!!!!!!
ITS A SKATER NATION !!!!!!!!!!!!!!!!!!!!!!!!!!!

Every set of 4 blades we had on our boat a while back had vibrations, some worse than others.... no issues with 5+ blades.

Well then.....
We did run some of them 3 bladed cutters a while back, ended up sinking with the broken propshafts!

Peter said back in the day when they raced with the 3 blades it was BRUTAL

I often wondered???
Can this be balanced out or is it nature of the beast?
(4blade)

Jim i'd say its the nature of the Beast sent mine back to BB!@des for a tweak and balance and came back the same .. $s for a speed run is livable 5s for just playin .. wonder how a set of 6 blades react

Yep Bill, that is what I thought, I have a set of 34 4 blades.
I would like to set up them on the balancer and see what that says? Just for curiosity ( Like I have time for that )
Blessed to be busy

LOL in the very early days we ran 3 blades on the Arnesons,I stopped and checked the "U" Joints more than once,those blades loading and unloading will cause amazing vibrations,Rolla with the 6 blades made them smooth as silk.
