Paintman - looking great! What type of paoint are you going to use?
Handy Andy - The PWC makers all had their own designs.. My Polaris has an aluminum wear housing. My friend's Sea Doo had a plastic wear ring insert. Some makers used stainless steel, or at least it was an aftermarket part.
Sucking up sand & gravel definitely chews them up!
Be interested how that holds up versus my Goop Coat-it. What kind of rivers are you on Paintman? I am usually on small round granite in the rivers round here..
