- GANSETT RANGER (2010) Yanmar 4BY2-150
Yesterday a Yanmar tech changed out both fuel filters on my 4BY2150.
I had ran the new to me boat about 5 hours previously on two separate days without any issues.
The system was bled according to the book and when it was started the engine alarm goes off and the display reads check engine. Immediate shut down, everything rechecked, restart and same alarm. Tech is guessing that it may have something to do with the water sensor in the primary filter that was disconnected. He later ran the codes in the system and it read #1 glow plug. As he went through different procedures the alarm would be intermittent. He was quite perplexed as what was going on, while I'm thinking a major repair coming my way. He located the culprit, unplugged it, plugged it back in and all seems OK now. After numerous restarts no alarms.
The shop manual states the water sensor would not leave a code.
Had I done this filter change myself and had the alarm blaring I would have been in a real tough situation, when it comes to electronics I'm at a loss. The boat would then have to be taken in for service, maybe towed, not knowing what was wrong and then pay over $90.00 per hour for diagnostics and repair.
Exactly what caused this we do not know at this time.
I will have 2nd thoughts about doing a filter change myself in the future. Perhaps it was just a coincidence but there were no problems at all before the fuel filters were changed.
