I have a 1997 Evinrude 200 OceanRunner model # E200TXEUA serial # G04307226. The motor is on a 22' center console used mainly in salt water. I bought it last year. Motor runs fine. I read where on a salt water motor that the thermostat & head gaskets should be replaced every year. Is this correct ? If not, when should they be replaced, or what should be replaced occasionally ?
Thanks,,
