I need to know the proper RPM range for a 1981 175 hp Johnson, completely stock. My Clymer manual doesn't even have that information in there. That manual is almost worthless. This is the first OMC I have had in a while, so I am catching up on the differences. Also, what temp. range should it run? Thanks.

Rpm 55 to 6000 stock is what I recommend factory sai 5250 to 5750. Thermos are at 140
