That is a fast boat with that power


gear ratio and rpms?

What's the speed difference between the stepped and non-stepped hulls? Are these good rough water boats?

FredZ - 1.5/just about 6 grand on the revs!


Stepped hull 27's are significantly faster on average than straight bottom hulls if all other variables are the same. Not sure about exact numbers. I can tell you 650 hp in an older straight bottom was showing aroung 80 mph. I dont think speed numbers would be linear though. As the step 27 increases speed, it seems to need less hp to gain more mph; shes very efficient aero and hydro-dynamically.

What drive are you using? any problems with it?

i got almost the same setup that is going in a 27 in the future. XR/sportmaster 1.35 and just over 800hp.
Thinking the drive is the weak spot?

You'll probably be on borrowed time with the xr. I run an imco scx/sc combo. I replaced the lower gear set at about 70 hours.

Anyone know how to get in touch with the guy that has the hull mold?

Not that you'd be running big numbers in rough water with a 27' boat, but I presume these are good in the rough? What is the hull based on? I presume it's a stretched 24x7?

Not sure what you consider fast for a 27' in the rough but I think you would be surprised. Very capable hull in the rough.

The hull is from Bill Farmer's 27 Excalibur. Wellcraft bought the molds in 84-85 and made them for a few years then Activator bought them. Years later the steps were added.

Well, presumably not 106 mph! Good to know. One of these might be a good upgrade from our 24 SB in a few years.
