I just bought a 88 prostar 190 (351w). I changed the oil before taking it to the lake. After the engine warms up and runs 10 munutes the oil pressure drops while the engine idles to around 10 pounds and the warning buzzer goes off under the dash. While the boat is running at any speed the oil is fine and no buzzer.Anyone know anything about this?
