What prop diameter is appropriate?
I also have an X-18 (1972), and I am thinking that a Solas 21 prop might give me a bit more speed.
My boat has a bronze prop and runs in the mid-50s at a bit under 5,000 RPM.
Engine is a Ford 351 with Cobra heads. No idea what horsepower, but previous owner built it for reliability more than output. The reason that I think a new prop might help is because the prop hub is a lot smaller than the drive diameter, so I am guessing that I am getting a bit of cavitation and slip. However, the boat is really stable at speed.
No idea of the pitch. Here is what it looks like. Any advice would be very much appreciated.
