I was told I was buying a 1996 Mercury ProMax 225. It has a Black Max 225 cowl. Was told orig owner changed the cowl because ProMax engines not allowed in local fishing tournaments & he cheated. Know for sure the S/N on the motor is 0B176194, has 3 dueces & is 2-cycle. Also told the orig owner thought it was 4-cycle, didn't add oil to gas & burned up the motor 1st week & Mercury replaced the powerhead for free. Both hard to believe. I replaced the gearbox w/20" 2.5L Sport Master & sales worm from Jaco's Marine in TN said that ProMax's were EFI f/day 1. It's on a Bullet 20 XD & is extremely fast (84+ on radar)Anyone know what I have?
