Just placed my order for an OJ stainless 4-blade with Discount Inboard Marine. They don't list stainless models on their website, but can get them.
Asked Karen some questions about the application and she referred me to Eric at OJ - 1(800) 359-9730. I told Eric that my S22 with a 3-blade 13x13 LH nibral prop gets to 42 mph and 5500 rpm.
Eric said that the Lexus likes to wrap up, and that he's a little concerned that 5500 is too low when redline's at 6000. However, he suggested not to reduce the pitch of the prop.
So, back to DIM, their price for the stainless was $355, and they gave the $139 briefcase and puller for $79 with the prop purchase.
It's a little more than what some other posters mentioned in this forum, but I like them, they're quick and pretty cheap. Karen is very helpful, and even repeated back all my RPMs, speeds and priorities verbatim. I'll use them again.
