I have a 26 hourston sedan with the 260 HP engine and the volvo duo prop drive @ 2800 RPM 24 miles per HR.my burn is approx.10 imp.gal. per hr. fully loaded with fuel and gear boat weighs 7100 LBS
Well there you go; can't get any better info than these posts!!My 26' is a soft top that has never been weighed but it has a single IO 320HP with a VP DPS / F3 prop set. At 2,800 rpm's I am turning about 21 knots or so and I cruise between there and 3,200 RPS that delivers 24 to 25 knots. WOT is 38 knots. I am not tracking fuel consumption as it has a 300L tank that is more than sufficient for the central Straits.
As I consider one day this may be converted to outboards, I would consider the Merc V8 300HP Verado and the 350HP DP Suzuki for singles or a pair of 175HP twins. The few Island Runners I have seen from the factory had twin power and I like the idea for redundancy and stability.
Given this data twin 150's could easily be downsized. www.boatdiesel.com has a prop calculator ($50 membership required). Given this known performance data from Aces, you could plug-in different HP numbers to see how it affects speed, and perhaps go from 6 cylinder engines to 4 cylinders & save weight - unless you wanna do 50.I have counter rotating twin 150 Merc 4 strokes on my 26 Hourston and that's enough.
Max speed is 47 knots on the GPS, cruise @ 3900 rpms for 26 knots and 10 gals/hr

You bet! It will be back in the water late April/early MayI want to go for a rip on this thing for sure someday!!
I almost went with 200's on the last re power but i don't really have much of a desire to go much fasterGiven this data twin 150's could easily be downsized. www.boatdiesel.com has a prop calculator ($50 membership required).

47 knots that’s to slow lol, some members here would say they need twin 300 hp to push that boat.I have counter rotating twin 150 Merc 4 strokes on my 26 Hourston and that's enough.

That is true! I’ve only honestly had over 40 a few times. I’m more of a fuel conserver47 knots that’s to slow lol, some members here would say they need twin 300 hp to push that boat.

Maybe it's your brain telling you to be careful. Going fast is fun, but the older I get the more exhausting it gets. Iv'e run Ucluelet to Everett WA in a single day & was VERY worn-out at the end. It's the one's floating end-up just below the surface that bob-up as you are going over them - rare for sure, but you can't see them. Down here in Puget Sound there are government boats that go around picking up debris- go north of Campbell River where the driftwood is 4-5 feet deep on the beaches in places when the tides are big is a different story.Anything over 30, and its pretty hard to see the chunks soon enough to dodge them [maybe its my eyes].

The latest casualty was the composite bracket holding my transducer on the transom. Lowrance wants US$50 for one. Fortunately I got the fire sale price at Island Outfitters.
I'm happy at 22-27 mph, burning 5-6 gph, and dodging chunks [most of the time].
Yup me too, mine top up at 40 mph in the bay on flat water, sketchy as f...k, anything over 30 mph where i fish on most days is stupid, unless you like having back pain for weeks after a 20 mile run, I think a lot of folks on here have prop selection issues more then HP issues on there boatsThat is true!
