Re: 1994 Evinrude 25 Hp. That Steams
Do you have the S.L.O.W disconnected. This engine should have S.L.O.W. and limit the rpms if overheat.
May depend on model. There were some changes on the water intake screens, but I can`t remember the year. A good long time dealer would have this info. Any grooves in the waterpump cup? If so replace cup and housing.
