Hello to all:<br /><br />I just purchased this engine in December.<br />It's a 1990 Johnson 120. Could someone tell me the RPM range of this engine? The engine is mounted on a 1990 18' Hydra-Sports Fish&Ski and has a Raker 13 1/2 x 20 prop. The RPM at WOT is 5300. Is this about where it should be?<br /><br />Also what parts would be needed to upgrade this engine to a 140 are can it be done? ![Big grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
