I have a Yamaha F115 with original gauges. The Problem I experienced is a flashing alarm indicator " looks like an engine block" on the digital Tach gauge. The indicator is just to the right of the RPM reading and just left of the fully trimmed out possition.<br />The indicator flashes 4 times then pauses then another 4 period flash, repeating itself.<br />There are no other buzzers or indicator warnings, and the engine is running OK.<br />The only thing I noticed on this motor during the day and previously was it jerked and misfired, when the petrol tanks was not very full, but still had plenty of petrol of course. This may not be related.
<br /><br />Any input , the user manual just say's this is an Alarm for a Motor Problem
