"Looks like you came up with a great product. I have heard of nothing but problems with the stock clutch on these boats.
This is going to make a world of a difference if this clutch
works as good as your regular version. I have two of them
and they work perfect! I think you priced them right too, less
than $100 is only a few bucks more than buying a crapy
stock replacement. Keep up the good work!"

It also has a thread-together output shaft and a CNC-machined billet stainless steel clutch bell, along with lightweight CNC-machined aluminum housing.
