I have a 2013 Yamaha F70 on a 1995 Lund Pro Sport 1700. The OEM prop is a 13.5X15 (K) and the performance is just fine, but I have decided to replace it with a (hopefully) more durable stainless steel prop. I bought one from Turning Point using their "Prop Wizard" - it is an Express, 3-blade, 13.75X15 following their advice. The RPM's dropped from 5800 to 4900, top speed by more than 10%. NOW, they tell me they have nothing comparable to replace the Yamaha "K" model prop. That being as it may, I am now simply trying to decipher which OEM stainless prop to replace my aluminum with.
Any help would be appreciated. Thanks
