You should be able to get it into the 40 MPH range. Play around with different props and you may have to up the nitro percentage. Give your new motor some time to get broken in and work on setup.

Sweet. I would love to see it doing close to 40. Do you think the .21 will give me 8 more mph???

How fast is the boat going as it is right now? Have you clocked it timed it or anything? You could upgrade to a racing engine, such as a novarossi or something. I bet this .21 would do it, that is if you have $400 to spend LOL. http://hyperprod.bizhosting.com/_pir...5_inboard.html

Can't say I do. I think I can get it close to 40 at least with the O.S.
