"The Tach on my 1997 Sea Ray 2
"The Tach on my 1997 Sea Ray 210BR behaves erratically. Engine is Crusader 5.7L 315 hp, 40 hrs on motor. Engine runs well. One minute the tach says 1800 rpm idle, next 600 rpm idle. Wot once showed 6000 rpm, then 10 min later 4500 rpm. Speedometer is also flaky. Everything else, radios, etc seem to work fine. Any ideas. Boat only has 142 hrs on it since new."
