nuthinfancy,
I think Fr. Frank's numbers are pretty close for the 25 seafari. 6000-6500lb give or take sounds about right with power, fuel, crew, and gear. I thought about dragging mine to a scale, but I haven't done that yet. Don't know the trailer weight and don't want to launch it in its current condition just to weigh the trailer.

But... Weight is one thing, weight distribution is another.

From what I've read on this site, and from communication with other owners of 25 seafaris, I think you should look long and hard at your decision to go with a bracket and outboard. The 25 seafari, in its original configuration, has a center of gravity that is high, and pretty far aft. That's why some seafari 25 owners have found ballast under the cabin floor, placed there by previous owners. It's also part of the reason Carl Moesly designed his patented automatic ballast tank system for the 25. If you replace the I/O with a bracketted outboard, the CG will move even higher and further aft.

As an example, CSC member Bigfluke owns three of these boats. One has been converted to a center console, but still has a big block I/O. Bigfluke is a marine architect, and his company in Hawaii has developed an unmanned vessel for the DOD based on the 25 Seafari hull. He says the 25 seafari is the most seakindly hull of its size he's ever run. Of the three 25s he's got, he has said the CC has the best ride because the conversion moved the center of gravity forward and down. It would be worth your time to read through his posts and maybe contact him to discuss the ideal weight distribution for this hull.

Sorry if I sound like a know it all. After all, you've owned and run your 25 for years, and I haven't even had mine in the water. But based on what I've read, I plan to replace the 270 HP carbed 350 I/O with a 300-350hp MPI I/O package motor and keep all added weight as low and as far forward as possible.

Whatever you decide to do, good luck with the repower.
