If anyone has Seloc manual 1406 for Mercury Outboards 1965-92 you should correct the following error:<br />Manual gives Operating Range RPM for 1988-1990 100 and 115HP as 5000-5500. <br />The correct numbers are 4750-5250. I contacted Seloc and they verified that their info was incorrect and would be corrected with their next printing. I have heard that these engines don't take kindly to being overreved so this change could be important.
