Engine dying

[greatrath]

Hello, I was out on the sea last weekend on my zodiac 6.5m rib with a Honda bf130 on the back. Conditions were choppy. After a few minute of running the engine stalled. Several times after that it nearly stalled. It appears to happen when the boat is coming off a high wave. It's as if the kill switch is disconnecting. I ran the boat at home in a tank, moving wiring looms etc to try to find the fault. Engine never skips a beat. I checked the petrol for water, it's fine. It does appear to be a breakdown some where in the electrics, but I can't find it. Sorry for the long post. Any ideas???

I had a Honda 150 doing the same thing. Mine turned out to be the main power lead near where it connects to the engine had broken inside the cable. It took 2 days to find!!! Prob different but worth a look.

if it runs blade type fuses (not sure if the Honda does) could be worth checking that the holder is gripping the blades tight..... Have had this issue with a couple of Mercurys now (main power fuse, causing same issue as you describe).

had a similar thing the plastic prong had cracked allowing the kill switch to close intermittently in rough water

Thanks for all the tips. Try them at the weekend.
