Can anyone one help?
I have a 1999 model Yamaha 115hp CETOL 2 stroke with a problem. When you start the engine and increase the revs to 1400 or above a warning buzzer sounds from the control box and 3 lights on the digital tach are flashing (see image attached).
The lights flashing are low oil (red) full oil (green) & yellow (oil can symbol). Once the alarm is activated it also cuts in the limp home mode and lowers the revs and there is a lot of vibration from the engine. At this point both tanks are full and you can smell the oil ok.
Once you reduce the revs to tick over it will go back to normal and the alarm will cut out.
So far i have tried a number of things. First i tried a new hand control box, then i put in a new tach clock, i have disconnected the thermo sensors mounted on top of each bank of cylinders, i have put on a different remote oil tank and all of which have made no difference.
I have cleaned the filter in the remote tank, i have also cleaned the gause filter in the header tank and still no improvement.
I have also fitted a new CDI unit but with no success. Items i have not checked are the emergency oil switch unit and the oil pump itself.
There appears to be a leak around the top of the oil float switch on the header tank. When the engine is trimmed you can see a drip of oil coming from it. Could this be a problem?
While running the engine in a barrel today i noticed a lot of water coming up from the lower unit and coming out around the rear of the upper cowling, When the revs are dropped back to tick over this stops. The engine is pumping water very well. Not sure if this has anything to do with my problem but i thought i'd mention it.
I am now at a loss. I hope someone can help. Thank you
