The Pro XS was designed as a “consumer motor” with the usual warranty and such. Ive only owned one new 2.5 (280 hp a “tad” under-rated) and it came with a “you buy it, it is yours” sort of deal, although mercury did fix a couple of electrical/electronic glitches no questions asked. We ran it on an STV racing hull, but hung it on the back of an Allison XB a family member bought (hull only, mid 90s manufacturing date). Thing would break 100 without breaking a sweat. Was too finiky to use as a fishing motor however, but he wanted to see how his ally hull would run and I had the motor in my basement. Those were simply good motors. Incredible torque, 400 pounds soaking wet, would wind like there was no tomorrow. However, theres a lot to be said for todays DFI motors also. Particularly with respect to fuel. My 2.5 burned over 35 gallons per hour wide open, around 7800 RPM. Today that would be a giant pain in the wallet.2008 Pantera Classic2014 Mercury Pro XS 200
