It's a beautiful mechanical design. Unfortunately It doesn't show anything about size, weight, or specifics regarding the 25.

If you compare the 71/72 25 seafari's to the 73/74/75 25's

There is a big difference in the cockpit/cabin stepdown. There is a LOT of empty space below the cabin floor on the 71/72 25 seafari's. I imagine this is where the tanks would have gone had the 25 been built by potter to moesly's specs.

It would of been sweet if it had the size of the orifice between the tanks and said the volume of the tanks. There are a lot of unknowns there still. That's why Im leaning towards a single tank just for weight ballast. Like Big said there is a lot less room under the floor in the later 25's than the first ones built. The good thing about the latter ones is that you can stand up in the cabin and have a ton of extra head room. Im not sure how much extra depth I have but it looks to be 8" or more over the others. There is still a lot of room in the storage compartment that a bladder tank could go but I am hoping to find room under the deck even if it is a shallow tank custom built to fit the contour of the hull. Welding aluminum is not a problem for me so I could build a odd shaped tank and add some foam coring under it for support and then glass it in solid so that it don't bounce around and support it well.

Getting geared up to get back rolling on the seafari. Went about 6 hours away to pick up power for the hull this weekend. Found an awesome deal on a second pair of 2.5 mercury 200 hp efi outboards. (Second to the pair recently picked up for the race hull) I know I know this boat would do better with a io but I'm going to give this pair of out boards a chance. They were in good shape, compression was 125 at the lowest on all 12 holes up to 129 psi as a high. Very good numbers. Came with all controls, cables, harnesses, full gauges that look new, props and every thing to rig and run. Hour meters were very low for the year. Best part was they were only 2k! Came with 17p counter rotation mirage props, what pitch do yall guys think the 25' will need. I have standard rotation 19p & 21' mirage wheels and wonder if I may need to get a counter to those 2) if the 17p's are to little pitch. Like to get the rpms at least to 6000.

2k for the pair!!!! wow that is an amazing deal. I'll be watching closely to see how you like the boat with outboards. Keep up the good work.

Thanks, I couldn't believe the price either. He wanted $2200 but got him down to 2k. I expected to find some old motors with burnt piston's but when I did compression checks the lowest hole was 125 and the highest was 129 and that was cold with the throttle closed. I done a leak down as well and they checked out really well. They also still have the serial Id numbers on the freeze plugs so they are original power heads not rebuilds. The only have around 350 hrs on them according to the gauges that came with them. I found a pair of carb 2.5s last week here locally for 3k. If they were EFI like these I would of got that pair too. Still might end up with them due to the guy may trade them for my 23' Proline and trailer. There as been some deals around on motors lately. Keep me in mind if you come across and Hipo 2.5 stuff. Still like to find some 7 petal fronts and some promax blocks if possible. Not for the 25' but for the race boat. The motors on the 25'will remain stock for now.
