I'm currently running an 11 pitch prop on my new 2007 Mercury 25 EFI. The motor is set back ~4.75" and the cavitation plate is about 2.5-3" above the bottom of the boat. Currently, I'm getting around 28 mph with 2 people, fully loaded, in a light chop. The speed seems fine but I feel as if I'm hitting the rev limiter. I was watching the GPS and it would hit 28+ mph and then drop to 25-26 and climb back up. The wind was going pretty good so it was hard to hear a change in RPM (plus the EFI is so damn quiet!
No tach yet...I know that complicates things...one's coming in the relatively near future.
Any EXPERT advice? I'm still awaiting an email reply from Capt. Ron but was wanting input from others as well.
I'm wanting this thing to be able to blast out of the hole, hold water, and get some good mid-range and top-end speeds. I'd be willing to sacrifice a little top end for some hole shot. Would still like to be pushing 30+ mph WOT, though.
Looking forward to some good responses!!! ;D
