BF 135 Engine fault alarm

Anyone have any experience to share about the engine fault alarm plus the equivalent of an automotive "check engine" indication for Honda BF 135/150 series engines?

All was fine last evening but this morning (Sunday of course) the starboard engine is refusing to start with the above alarms. Port engine is fine so it's not water in fuel and anyway we have run for about 5 hours since the last fill.

According to what I can find on the "net" there are 13 sensors which can set this condition but the most likely is the O2 sensors getting contaminated by water and we did get very large amounts of various colors of sea water over the boat crossing the Straits of Georgia yesterday. Seems we picked the wrong course and got a serious dose of wind vs BIG tide. A fellow traveller was about 5 miles North of us an had an easy trip. Nice to know we can handle short sharp 6 footers for 3 hours but I feel like I have been wrestling with an Octopus today.

So we are stuck in Pender Harbour (with an "o") waiting to get in contact with the local Honda repairman. By all accounts he might be a little difficult to get to even come see us so we might just have to go on one engine to Powell River where they have two dealers and some competition !!

Happy Fathers day :-)

I'm not sure about the 135's (although that's what I have now). However, on my 40's I had one of them alarm continuously when the engine tilt sensor was bad. Might want to check the tilt sensor since those things often get stuck.
 
Thanks Roger, I remember those little boogers from my BF-50 days. Think it's a different system on the 135's and I checked the indication over the full range and it seems OK.

Sorry, can't help. I can only imagine it could myriad different possible problems. The "brain" is interpreting the issue and doing what it's programmed to do. Probably need a computer diagnostic reader to get the error code. Gotto love modern engines. Good luck.
 
Merv:

I don't have enough experience with your motor to speculate on the cause of the problem you describe, but do think you're being too quick to eliminate water in the fuel. As I recall, your motor has two in-line fuel filters under the cover, one of which has a water sensor. It's easy to spot a filter with a sensor - it's the one with the wires on the underside. The fact that your other motor is running fine doesn't mean that you don't have water in the fuel - it just means that not enough water has accumulated in the other's filter to make it shut down too.

If you want to eliminate the possibility of water in the fuel line, remove the sensor equipped filter, drain it, and then reinstall and refill. If that solves the problem, I'd do likewise with the other motor's filter.

Hope it's something this easy to fix. Good luck.
