115 4 stroke oil warning
Just a clarification based on comments received. The 115 4 stroke does not have an ECU...one model year too early for this feature...at least that is what I have been told....it is the oil warnng light and not the engine overheat light. The thermostat was changed per Yamaha because they originally felt with low hours the engine oil was being contaminated with gas. And finally, the oil warning has been going off for 9 years. This year was the worst of all the years and the boating season is just starting. It is in fact the first year that I was able to duplicate the warning light for a service center. They then checked sending unit, oil pump etc. and found nothing wrong. That is when Yamaha said the engine should not be filled to the full line with oil. The engine has been maintained every year with new oil, filter etc by a Yamaha dealer. Expect a visit from Yamaha rep soon....keeping my fingers crossed.
