Hello All, Need Help with oil injection!
I have recently purchased a 1989 90 HP on a 17 ft Boston whaler, seems to be running fine and getting oil, light smoking and slightly oily plugs. Oil Tank is full, but the yellow indicator stays on. The dealer I purchased this from is at a loss.... although they are trying to help. They emptied and cleaned the tank, cleaned a filter, and replaced the sensor. Also ran new wires to the gauge from the sensor. Unfortunately, they are new to Yamaha and have been mainly selling 4 Stokes. We all thought that this was an oil problem because the red indicator and audible alarm would go off after about 15 minutes.
Turns out that a piece of an old impeller was stuck in the water tube. That was fixed the alarm issue, telling us that it was the temp sensor setting off the alarm, but the warning would also set off the red alarm indicator... The operators guide states that only an audible alarm would go off for the temp warning, not the red indicator. Could wires be crossed or connected improperly? What can I check next?
thx Jon
