VerifiedHi, welcome to Justanswer. My name is ***** ***** I'd like to help with your question.
The system may prompt you for a phone call,
this is an auto response and I did not initiate it. If you'd like a call, please request it,
otherwise I am happy to help you via our message system here. I'm sorry for the delay you've
experienced, I've just come online and saw your question in the queue.
In order to get more speed from your setup you will need to go up in pitch and possibly down in diameter. You will probably need to be able to run a 14 pitch by maybe 9" prop to get the speed you're looking for. It would also be helpful to know what maximum rpms are to better tune the prop in. Also you need to figure your mid range load so as not to prop too high or low.
