I had one on a 22 Velocity CC. It was a great motor, good on fuel and had great manners, it was no problem at low speeds. The new owner of the boat changed the motor to a 250 E-tec and picked up about 4 mph though. The boat ran 62/63 mph with the Merc. We were really amazed at the performance of the Evinrude over the Mercury. Hope this helps.

Cheers,

Andy

Speed and fuel burn all depend on the boat you put them on. There is a boat with twin 250xs Opti's in my neighborhhod it is a 30' center console and it runs 80.

I have a set of 250xs on my 36 concept. They are awesome motors. I top out at 64mph.

EXCELLENT fuel economy

Strong, trouble-free and relatively quiet... great power!
