I'm just back from another fantastic sail on our Hanse 301 Swn Y Mor but when we were motoring back in the engine died back down to about 1000rpm. It didn't stall & got us back fine. But every time I put it back in neutral & then up to about 3000rpm to motor it quickly dropped back on its own to very low revs. Has anyone ever had anything like this or any idea what it could be? |

Richard,
This sounds like a fuel starvation issue. Check (or replace) your engine mounted fuel filter, check (or replace) your in-line fuel filter (Hanse seem to use the Bosch as standard). Before you do any of this, however, you might check to make sure that any valves between the fuel tank and the engine are clearly in the 'open' position. It's also possible you may have wrapped something around your prop or, if it's a folding version, it may not be opening properly. If either of these were to be the case, however, you'd likely be noticing a fair bit of vibration, which you did not mention. So, more likely a fuel starvation issue.

Hi, It looks that the engine is starving in high revs only. This can happen if the fuel/water separator is almost full with water and the protection valve is almost closed. Bleeding the water out of the separator will resolve the problem (with the engine off). ------------- Panos Hanse 630e - selling her - |

If it were me I would also check the water separator a Panos suggests. I had a water problem early spring this year.

Similar thing happened to me
It was diesel bug in the fuel clogging the fuel line
I flushed some of it out then used a bug inhibitor & ( touch wood) have not had a repeat . It looks like a black jelly.
I add the inhibitor at end of each season & fill the tank to avoid condensation
It seems to do the trick as I do not add it very often.

Hi Richard, as already said change the filters, you need to take them off to check so may as well change them. If you the primary is the volco glass bowl type (mine is) you can drain water out of the bowl, but the filter itself may be clogged up. Can get a bit messy changing the primary, depending on where it is located. I change both filters once per year. ------------- Steve. Hanse 341 Echo of Wight, .

Dave,
I think Bovine has his 430 in Cardiff. You should go and buy him a drink.  ------------- Happy sailing. [IMG]smileys/smiley1.gif" align="middle" /> |

I went to the Cardiff marina yesterday not penarth, as I had won half price marina fee for a year, was not impressed, i know it is a young marina and to expect building work but poor toilets, and showers and a long walk to a bar. NOT good, so sadly I wont be taking them up on their prize.
 I was hping to use it only for a the iwnter and a few weeks in the sumer as a spring board to the scillies or France but it was not to be.

thank you all who suggested the solution for my engine problems - it was fuel starvation caused by a block of diesel bug in the primary filter. Thanks also to "Advance Marine" of Portishead who sold me the right chemicals to kill it off & filters to replace as the dead bug comes through the system.
We sailed again today the engine worked just as it should (& I've also learned a bit about diesel maintenance ! ) Cheers Swn-Y-Mor |
