Hi All,<br /><br />My engine is currently being repaired in the engine repairer's but when it is done i would like to get a little bit more top speed without the expence of buying a new engine, <br /><br />Could someone please point out the prop sizes that i can use on this type of engine. i dont know what size is on at the moment. <br /><br />How do i measure the current prop size? <br />Is the size stamped on the prop?<br />What would you advise me to change to?<br /><br />Thanks
