I made a mistake I have a 12-3/4 x 17 4 blade, not 19" pitch.
Still tuning, about 29 kts/ 33MPH at 5500-5600 RPM. I haven't synced the carbs yet and I am not sure I get them wide open.
This hull is awesome out in the slop. I accidentally planed it straight out of the mouth of the Merrimac this week. It seemed a little rough going over the standing 4 foot waves at 18 knots! That stupidity would have swamped my other boat.
Other than when I was at WOT heading into a 10-15 kt breeze off the starboard bow, it was a super dry ride.
It would have been perfect if we caught fish and the 11 year old tilt/trim didn't quit (looks like worn brushes). But still better than a day at work.

Well, I finally got a chance to test it.
I have a 20' Master Angler with a 100 HP "Yamadog" Yahmaha four stroke. I have a 4 blade 12-3/4 x **17** Amita aluminum prop by Solas.
I have the 2 batteries on the port side of the forward part of the center console. A 20 gallon aluminum tank is up there too. The center hull tank has been pulled and replaced with buoyancy foam.
In addition to the ~376 lb Yamaha F100, I have a 6 HP 25" shaft pull start Tohatsu SailPro with a 6" pitch prop as a kicker.on the starboard stern. It has a 3 gallon tank that sits in the center console.
So balance fore- aft isn't awful, but the weight at the stern is probably 430 lbs with no kicker. And with a starboard helm, that isn't great. But the transducer seems to help, maybe?
With the batteries and tanks forward, the deck drains are above water, perhaps by 1" at rest. With a stock deck.
On the maiden voyage, it pulled 5400-5500 RPM with a 2nd passenger for 28.0 kts before I ran our of river (maybe 200 yards between buoys). With a little under 400 lbs of passengers, perhaps 16 gallons of fuel, and 75 lbs of tools and another 50 of anchors and tackle.
With some practice tweaking the trim it might pull 30 knots if I can run for a few hundred yards. It planed down to 12 knots with improper trim, maybe a bit slower, even.
It has no problem getting and keeping the stern out of the water. I knew it wouldn't be fast, but in the channel chop I was outrunning any boat even close to my size. And the ride is amazing.
My single beef is the stiff feel of the Teleflex SAF-T-STEER no feedback unit. It is brand new.
I suspect I would have a higher top speed with less drag with a conventional foil, but would fall off plane faster with a cavitation late foil. I have the large size hydro-shield. It comes of plane very softly. It is quite nice.
It bogs out of the hole, as I was told to expect, but as bad as an older two stroke, and I rebuilt the carbs myself and haven't timed the throttle sensor or synced the throttle shutters yet. So there is a little more left in it yet to aid in power and holeshot, I think.
Thanks for the tip Fr. Frank!
