Hi All, I've been running a standard alloy prop on Henry B from new. WOT at 5000 rpm gave a top speed of about 15 knotts with the 12/14" x 9" alloy prop the boat came fitted with. Two crew and all the associated fishing paraphernalia. Changed to the prop to a Stainless Steel 10 x 5/8" x 11" and the difference is amazing. The stainless prop has a more progressive pitch. The alloy prop is much flatter in appearance. I now have a top speed of 19 knotts with a WOT of 5000 rpm with the same load. Also uses a lot less fuel which was a pleasant surprise. The motor does not sound as though its at bursting point as it did with the alloy prop. It always seemed as though I was driving around in 3rd Gear and the prop change has proved it. Mikey B
