As far as performance goes, this one is quite a bit different than how it started. Originally, as a Sceptre, I had a 2001 225 OX-66. Top speed was just at or under 40 mph, 4000 rpms was about 24 mph and I think around 4700 for 30 mph. I was getting a little better than 2 mpg cruising in the 4-4500 range.
Now I have a 2004 F225 with a 19 pitch SWS prop (I believe 15 1/4). I haven't put much time on it yet, but with 4 people and half a tank, I was seeing:
4000 rpms - 26 knots (30 mph)
4500 rpms - 30 knots
5700 rpms - 41 knots (47 mph)
That was going into a 10 knot wind. I didn't compare numbers when I turned around.
I didn't have the fuel flow hooked up when I ran those numbers. Since I've installed it, I've only gone from the boat ramp to the lift, so I don't know where I am fuelwise yet.
Some other performance notes. I was a bit concerned about how the weight would affect it. I'm probably 1000# lighter than when I started (and getting 47 mph with an F225 confirms that). There were whitecaps on the bay the day I took it out, and if anything, it handled those conditions better than it did originally. With everything fiberglassed together, it feels much more solid - no rattles or noises at all.
At idle, there is a little bit of squat. Not much, but I can tell the difference vs how it was as a Sceptre. It jumps on plane easily with very little bow rise. I didn't play with the trim tabs much, other than just to make sure they were working correctly.
I'm planning on doing about a 100 mile run on Saturday for a spearfishing tournament. The forecast is for 10-15 all day, so I should have a better performance report then.
