"Hiya
I have 2 Honda 225hp motors on my boat. They are 2007 models and have about 200 hours on them.
My port side motor had its oxygen sensor replaced a few months back and the boat ran fine after that.
The same motor has now started acting up. When running at a constant speed, say 4000rpm, the alarm will sound once and the rev's will drop. After a second or two, the rev's will jump back up to the 4000rpm mark (or what ever rev's i was running at), and the motor will run fine for a while again.
This will happen occationally at idle too, with the alarm sounding once, rev's dropping and then bouncing right back up.
My honda dealer has hooked up their diagnostic computer to the motor, but it says everything in fine.
I've checked the fuel for dirt and water. I have an inline filter and a Racor filter with a water trap before the fuel goes into the motor. Have replaced the fuel hoses, replaced the filters, cleaned both filter on the motor, the water trap and the fuel filter.
I run my boat at 3200-4000rpm and it happens through-out the rev range. My thought was that i could be water in the fuel or fuel starvation, but i've now ruled out both of them.
Any idea's??
Regards
