Now, while we are in the engine room.
Did anyone find a engine room blower less noisy than the factory mounted? Mine is from "Attwood" and moves 6,7 M3 / minute in a 100 mm / 4" tube. Jabsco has a 7,1 M3 / minute version. But is it less noisy? |

Obviously sleeping while I'm typing this mail. Just got in Europe 1 day ago. Needless to say I don't push good days of work still, because I don't fall asleep and the mornings I wake up at 12.
People that travel for work oversea's I don't know how they do it....... Anyway all the info you are giving me is really the way I like it , conceived, no ambiguity, even the particle mistakes we usually are said. Thank you for all this . I will try to get my eye's through the right holes and start the job. Have a good day. Here no sailing for anybody " Le Mistral " is out for 3 day's 35 knots!!!!! Thanks Jean usually from Montreal and yes missing the well known Jazz Festival

Mine is very quiet. In fact it does not exist. There is no engine room blower on my 320 as the factory stopped fitting them. Charles |

We have an SD50 sail drive and at the very front of it is about 4 or 5 slits, this is the water intake and we had weed over it causing steam to come out of the exhaust.
Motor backwards and see if it clears, fortunately for us, we'd come out of Cowes in to the Solent and the tide, together with a lumpy sea it cleared itself by the time we needed the engine again ! Suggest a diver inspects to ensure is clear if you don't fancy running the engine.

Ours had been disconnected unbeknown to me. It was reconnected by our repair man when the engine was serviced earlier in March 2013 and it sounds absolutely terrible, especially when the engine is idling. I seem to recall that this may have something to do with its location being against a bulkhead and vibrating. I know that some owners have disconnected theirs and others have purchased replacement units that run quieter!  |

Surely if you have a rubber 'washer/s' between it and the solid wall some of the vibration would be taken out ?

Mine was already on the noise protection but still quite noisy. Actually louder than the engine when idling. I disconnected it years ago. Nut now I have isolated the engineroom very tight so I guess a blower will be needed.

I used 30 mm isolation from a marine store called Biltema. It's approved according to EU regulations for leisure crafts.
http://biltema.se/sv/Bil---MC/Bil-tillbehor/Ljudisolering/Ljuddampningsplatta-369214/
The plates are 500 x 1000 and i used 7 of them to be able to cover the entire machineroom. They are self adhesive so it's quite easy to just put them over the factorymounted 10 mm plates. I also bought 50 meters of special tape to close all sides of the new isolations plates so everything is fireproof - and looks professional. From the 7 plates I also cut 2 loose pieces I have stuck down from the back over the gear and air tubes. I could not find a way to fix them permanently - it would make servicing the SD impossible. I have seen the same product in an other marine stores so I think it's possible to order in other countries. E.g. hjertmans.se, serach for "Motorrumsisolering, CE-godkänd " |
