Location: Pewaukee, Wisconsin		You might have the S.L.O.W system kicking in. When the engine overheats or isn't getting oil it will limit RPMs to 2500, basically enough to get you back to the boat landing. Not saying that this is it but it is something to check. I have an 1989 Evinrude, had the same problem, it was a bad blocking diode that was setting off the S.L.O.W system.
