I just bought a 1994 ranger 374v bass boat with a 1994 Mercury XRI 175hp 2.5L. I have rode in boats with these motors before and there was always a beep when you turn the key on to let you know the warning system is active. Mine doesn't do this. I have drove the boat about 4 hours since I got it and it is pumping plenty of water and oil. There is always some smoke while its running. As added measure I put about 4 ounces of quicksilver oil to the 5 gal I put in each tank of gas just for peace of mind knowing there is some oil going to the motor incase something happened.
Where do I start looking? All of the wires seem to be hooked up at the motor. There is a little black box under the ecm with a red light on it. I figured this might be the buzzer. The light doesn't come on when I turn the switch to the on position. Also, under my dash there is a tan wire with a blue stripe with a terminal end on it that isn't hooked to anything. This appears to be close to the same tan/blue stripe wire thats hooked to each head.
Where should I start. I don't like running this thing without some kind of warning system and obviously someone either disabled it or something stopped working.
