I Love microskiff.com!
I got my HB professional tunnel with the 60R propped with the Mercury spitfire xp 14p (its not the correct prop IMHO) this past weekend. I ran it for about 3 hours (its cold here in Texas). I know a lot of people were wondering about the performance, What questions do you have? Hopefully be able to answer some of them. Jacked up on 6 water pressure was a solid 18-20 psi. I just need to learn how to drive it, we we running in about 6" soft mud bottom in a back pond and needed to turn around, started turning and rear end got light and lost momentum. She still floated.
