numbers on my sons seafari 25

[badhabit]

we installed some electronics on it and took it out sunday. we had about 70 gallons of fuel and 5 people on it. I played with the trim and was able to get 5600 rpm and 35kts at wot and 26kts at 4400. she is a wave crusher but pretty hard to keep level, I was constantly moving the trim tabs. if you did not see the other thread it has a 225 etec on a notched transom.

Thanks for the post and the numbers!! That's pretty darn good for a big single with 5 people on board. As far as Trim Tabs and constant adjustment . . . here's an email directly from Bill Potter (back in 2007?)

"Hi Tim,
Please tell Strick he has the best riding SeaCraft we ever built. It is not a boat for someone who doesn't know how or doesn't want to use trim tabs and the power trim of the IOs or outboards to get the most out of the hull design. The boat has the deepest V (25degrees) of any SeaCraft and, due to having no lifting strakes, it is more sensitive to "leaning" in cross winds and from weight shifts while on plane than other SeaCrafts and other deep Vs. BUT, it is like flying an aerobatic plane, if you know how to use the trim you can set that boat up to run through anything you have the nerve to be out in with remarkable comfort and safety. AND, because of the Variable Deadrise Hull design it is a very stable platform at rest or at trolling speeds. I wish we had a recording of the story a guy told us about his run from St Croix to St Thomas during a major hurricane flying through and off 25 ft and larger seas in the dark! Pigs don't fly!
Best regards,
Bill Potter
ps A SeaMark twin Fiberglass Bracket and properly positioned and operating trim tabs would be my recommendation unless he is going to go with a big single diesel duoprop stern drive or smaller twin duoprop sterndrives. ( Duoprops minimize torque roll)

Good numbers. i'm a little surprised a 225 would do that well.

The 25 is, for sure, a drivers boat, and, oh boy, does it reward a skillful driver. It took me a couple of trips to learn how to get the best out of it. Its easy to drive once you get the hang of it, but it still requires attention if its snotty.

I agree that's better than I would have expected, but most E-TEC's are strong running motors. That "225" is really about 240 hp at the prop, with lot's of mid-range torque and probably at least 500 lbs less weight than an I/O, which probably explains the excellent performance!

The ride is other worldly.

Why I love 2 strokes.
Torque baby.
And where you can use it.

The G2 250 has 600 ft. lbs.
600!

putting the 23 next to the 25 . . . 25 is about 1ft narrower than the 23 and about 1.5ft longer. The hull weight isn't much different either.

Good numbers OP. Lets just clarify on the G2 Torque. Yeah it has 600ft lb AFTER accounting for the gear reduction. Not even a 3l diesel has anywhere near that torque AT THE POWERHEAD.

Bs,
Are these waterline measurements? Interesting.

[cdavisdb]

1.5 feet longer sounds about right, but the beam on my 25 is real close to 8 ft, probably exact. Isn't the 23 also 8 ft?

I've stood next to all three, 21,23, and 25 together, in the water. There is surprisingly little actual difference between the three, way less than you would think. In terms of usable space, Moose's 23 Septre is far bigger than my 25.

[Bigshrimpin]

I measured my 25 above the above the waterline (where I'm mouting a bracket) at 82"
Roughly the same area on the 23 is 90" if I remember correctly. I can measure again tonight when I get home.
