Phil,

With regard to your prop recommendation I've read some of the posts on Etec's and props. Most of the pitch recommendations were 17".

I read the following evinrude information on pitch:

"A low pitch allows engine RPM to build up quickly, which gives faster acceleration and more pulling power. This works well for heavy loads, but results in slower top speeds. Higher pitched propellers are similar to high gears. They create more forward travel with each revolution. A high pitch puts more load on the engine, which reduces low speed pulling power and acceleration, but usually
provides more top speed."


I was wondering if your 19" pitch recommendation was predicated upon my particular loading condition; and upon the combination of Etec's renowned hole shot acceleration and the 19" pitch (providing a boast to top end speeds). Am I wrong?

Thanks.
