Just bought a pontoon with a 1996 Evinrude 50 HP, model E50TLEDS. This motor is and always was an oil mix – it never had VRO. While moving it from the dock to my trailer I accelerated to approx. 3500 RPMs and the “No Oil” light and warning horn activated. After about ten seconds, both turned off. Meanwhile, I had cut the motor to idle speed. Back at the dock when I first got on board and turned the key, the systems check did what it was supposed to do: sequentially tested all four systems and the trouble horn. My first question is, why did this happen, since the motor doesn’t have / never had the VRO system? My second question is, how do I prevent this from continuing to happen – do I disconnect the tan/yellow wire from the tachometer /systems check gauge? (Similarly, I have no need for the “Low Oil” system check either since there is no oil tank. Would I therefore disconnect the tan-black wire also?) The previous owner said he never had this problem. Between his ownership and mine, there was a new power pack installed: could this be a factor?
