A 250 SHO to a 300, is only about a 25 HP difference if you were to see the dyno charts. The 250 SHO is apx 265hp, and the 300 is high 280’s. As to the 250 offshore, not sure, but don’t think it is as strong as the 250 SHO, could be wrong on the newer ones. I think the 250 offshore was 87 octane vs 250 SHO’s 89 octane, and listed a slightly lower rpm range for the offshore. Might want to ask the boat center to know the real deal on that motor. That 250 is an odd motor for the 2200’s given that their packages come with a 300. Sound’s like a guide boat with those hours.
