on the evinrude web site under performance reports they set up a 188 with a 200 HO. the motor height is the cavatation plate is 5.75 above the bottom of the boat. on my 2007 190 with a 200HO That would put the prop shaft about 2.25 below the pad. that sounds to high for a champion. the speed on the report was 68.4. i was thinking of setting my boat up like the report what do you think.
