Hi,[FONT=&quot]all,[/FONT]
[FONT=&quot]I just bought a new to me 16’ smoker craft with a 1993. 50hp merc 3cyl.on it.ran fantastic, but noticed a small oil leak,so I changed the oil lines,(very brittle)from the bottom of the built in tank, and now the out of oil buzzer is going off, there was air in the line, so I mixed oil in the gas and drove it for awhile but it still won’t go off, do you have to bleed the air out of that system [/FONT]
[FONT=&quot]Thanks in advance for any info.[/FONT]

Float stuck down, magnet has come off in tank, or tank wire not hooked up as motor does not have any flows sensors.
