I have an old merc' ser.#2665482. I am tring to find out what year and hp.Inline6,thunderbolt ign, red/orange and silver decal around the middle of cowl. It says 90 hp but is not listed in none of the numbers I have found.
By the serial number is looks like it could be a 1969, 100hp or 125hp. <br /><br />To determine which we need to know the carb number. The carbs on the 1000BP are KD-3A and on the 1000SS they're KC-10A or KC-14A. <br /><br />On the 1250 they are KC-1A or KC-1B, or KC-2A. On the 1250BP they are KD-3A. <br /><br />So, hope they ain't KD-3A. <br /><br />Get back to us.<br /><br />Chris.............
