Currently in the process of re-powering a Young Brothers 40. Caterpillar 3208TA (375 hp) is coming out and a SisuDiesel is going back inside. If anyone is interested in becoming the happy owner of a Caterpillar let me know.

That is your displacement, not the weight of the vessel.
A six knot jump eh? Rails for sure and like 300 ish, 250 for sure, over square the wheel to handle the torque. Might be time for some dieting for the ol' girl too. Strip that deck and timbers out of her and give her a race track upgrade.

Spoke with the owner today and they said that they would take 6K for the 3208 with the 507 gearbox. Engine has 4,000 hrs on it. New injectors were installed last winter. Comes with engine panel and wiring harness. Boat made the trip from NJ to Maine without a single hitch and when I ran the boat prior to taking it to the shop for the engine swap the engine performed great, hit the button and it was running. Very clean setup.

Shame to turn this sweet running engine into a parts engine, but once it's yours you can do what you want with it.

What will be the weight savings and hp difference with the new Sisu?

Around 500 lbs less, the steel angle engine mounting bed alone was 200 lbs for the cat. Switching from dry to wet exhaust, that will shave off a few pounds. Putting in a bigger shaft, about 58 lbs heavier, but the shaft tube should offset the weight of the stuffing boxes, might even be lighter in the long run. New transmission should be lighter than the 507. 35 more hp at 700 rpms less. New rudder should be about HALF what this monstrosity was (it was assembled, bolted, then welded together. not all that impressed taking it out really) and it was made of steel. Not stainless, but steel.
