I have a mid 90s yamaha 70hp precision blend 2 stroke.
Yamaha outboard oil tank sensor bypass.
I was starting it this morning and as soon as i turned the key the alarm buzzer went off.
I turned it off and tried it again several times.
Remote tank sensor remote tank pump.
But with alarm blarring and remote float at full level tank would fill.
Fwiw while trouble shooting i replaced the following for naught.
The oil tank is full.
I have a 2001 yamaha ox66 where the main oil tank on the engine is not filling automatically.
Need to find the seal.
The seal is designed to live its life in the oil supply.
The yamaha outboard alarm system can fail just like any other system on your outboard.
Yamaha outboard oil warning light repair.
Troubleshooting the alarm system includes making sure the horn associated with the alarm works making sure the warning light comes on and the horn sounds when the oil level drops below acceptable levels and ensuring the warning sounds if the engine overheats.
Its purpose is to force oil to flow through the strainer and not bypass the strainer at the nipple.
When i locked float to empty position on remote tank.
The remote oil pump would not turn on.
They sometimes are dislodged when the gauge is being removed and it can wind up at the bottom of the oil tank.
Having an issue with my 2000 200 hp yamaha ox66 outboard motor.
I have had the outboard for 4 years and this has never happened before.
The oil leakage now might be the least of concerns.
