Welcome to this new Egg Harbor Owner’s section on propulsion. As noticed by the many entries within the forum section we decided further investigation was needed. We poled the EHOA membership as to what is happening with their vessels in hopes to demystify the propeller mystery. This section makes no claims as to the exact propeller specifications, but we feel the more you know, the less guesswork it will require to achieve optimum performance.
Our first research project consisted of 1982 and newer 33’ vessels. We have a table below that provides you with membership data relative to avg. cruising specifications and wide open throttle (WOT).
You must remember that every owner has a different approach to maintenance, extra weight and cruising requirements. Some owners are very careful with measuring the numbers, others know only approximations. But the data is still valuable when viewed overall.
There have been great strides in the manufacturing and testing of inboard propellers these last few years. These new methods have produced claims of improved efficiency and higher cruising speeds. But we must keep in mind the most accurate propeller cannot replace poorly performing power plants, inferior bottom surfaces or over weight vessels.
Two very interesting articles worth reading are here for your viewing:

Major improvements with striping bottom and reducing weight. Will be trying 4 blade 19x19 Austral Nibral in spring ‘99 |
