Dear Daniel,
I think the best ones in term of quality have the lead film inside (as far as I can understand the lead does not "absorb" the noise but is a great barrier), but of course this stuff is really heavy, so when you have to access the engine you must hoist a considerable weight. Why don't you think to install this kind of panels on the bulkheads and less heavier on the engine removable box...? |

Daniel, We also replaced the original noise insulation with EC Smith type panels. (Interestingly the original stuff passed the MCA surveyors “match” test). It made a noticeable difference and is well worth the time and effort. With noise insulation, devil is in the detail. So worth taking your time over the joints etc. But as Lars says you will always get some leakage from the air hoses and where the stern tube exits the compartment. You will also get some structural born noise. Other than making the seats heavier as it will help to dampen out the vibrations, there is little you can do as its inherint in the structural layout and detailing of the boat. If you have space, a big difference will be noted by insulating the underside of the floorboards above the prop shaft. Wrt fitting, worth spending a little extra and getting the panels with the self adhesive backing. A lot less messy than pots of Evo stick. All the best Adrian |

Daniel, I can support that also insulating the tri-angular floorboard in the aft makes a big difference. Do you have a hard coupling between the shaft and the engine or do you have semi flelible coupling with rubber which I am told also greatly reduces the noise levels? John B |

Daniel, FYI on mine ,no 010 I need to remove the steps obviously, then I take off the handle on the engine box and it lifts out in one piece. But it is a tight fit. |

Following John´s advice, yesterday I happily succeeded in lifting the engine box out of the boat. |
