90hp Johnson "No Oil light"

[tclark78@hotmail.com]

I have a new 2005 90 hp 2-cycle with 4 hrs on it so far. I have premixed 50-1 oil in the fuel tank and have oil in the oil tank. The first 3+45 hrs on the engine were perfect, then while pounding through another boats wake the "No Oil" light and horn came on. I shut the engine down, checked the tank(it was full)and pumped he bulb which was still very firm. Started the engine, light was out. Five minutes later horn and light came back on. Since I am premixing the fuel during break in I was not worried about engine damage. A few weeks later I put the boat in and cranked it up and the same thing, light and horn after a few minutes at idle. It all started after pounding through another boat's wake. Any ideas?<br /><br />Thanks,<br />TCPC

Re: 90hp Johnson "No Oil light"

I would be looking at several things, in this order.<br /><br />1. Chafed wires (rough seas) at the engine.<br /><br />2. Faulty guage.<br /><br />3. Faulty wiring, at the helm.<br /><br />4. Water in the oil tank. remember, water is heavier than oil and sinks to the bottom.<br /><br />Keep pre mixing until you figure this out. Also, mark a line on the oil tank and see if it is actually using oil.

I'd be calling the dealer you bought it from, and getting someone on the job "pronto" !
