I just purchased a mass of sound proofing panels from SailorSoulutions. I have a pretty good idea of how and where I want to install them. I am looking to see how other s have done the same job.
My boat came with brown perforated boards in both sail lockers that fitted in to place, separate the engine space from the lockers. Is this common with other boats?
What did you mount the panels to to sperate the lockers and engine space.?Once you put the panels in place did you notice a great increase in “heat” from the engine space? Any concerns?
Pictures?
thanks
Alan

Alan,
I have only put the panels on the inside of my new engine cover. http://www.svsarah.com/Sarah/ewEngineBox.htm
One of my projects this year is to complete the insulation of the aft portion of the engine compartment. I have the same perforated board (I've replaced the original twice), but I don't plant to put the insulation on that board, rather fit some thing 1/4″ plywood in front of the fuel tank and over the gaps on the side – then attached the panels to that plywood.
With just the engine box covered I still got a significant reduction in sound over the original cover, which had virtually no sound proofing on the sides. Of course some of that sound reduction could just be the new engine. No significant change in the heat from the engine box, but again too many things have changed (box, insulation, engine, engine bed) to make any comparisons with the previous arrangement.On Wed, Jun 17, 2009 at 7:36 AM, Alan < ([email][/email])> wrote:

I wrote an article on this a few years ago. The zipped file with photos is about 13MB, so I won’t mail it. Instead, you can download it from my server at:

IMHO, soundproofing the engine cover and putting a baffle at the bottom of the instrument compartment will give the most bang for the buck.
http://www.richardcarter.net/boat/pix/exhaustBend.JPGThere are many products available for use as soundproofing. I used lead foil. Its heavy. I used sections of pegboard to hold the product in place (more weight). It works well and does a pretty good job. Peter used some stuff that looks easier to install.
I didn’t sound insulate the back nor sides of the engine compartment because it would have been too difficult. I believe that if you can’t sound insulate the engine from the bilge, you won’t get much benefit. The bilge is like a sound chamber. A lot of noise comes from down there. Some if its from the V-drive. I replace my V-drive 3 years ago. The new V-drive is quieter.
A lot of engine noise comes from the air intake. If your engine doesn’t have an air cleaner, adding one will dramatically quiet the engine. Adding an air filter to a diesel isn’t easy or cheap however. Airsep makes one that can be adapted. My Yanmar has an air filter so I don’t need to add one to it.
Keeping your running gear properly aligned so as to reduce vibration quiets things too. If your doors and floorboards rattle they can make quite a lot of noise.
You need to insure that your diesel gets adequate ventilation. The 424 engine room is open to the bilge and to the lazarettes. This provides enough ventilation without running a blower. If you close the engine compartment off well enough to hide the racket, you’ll have to run a blower to keep air circulating. Blowers are pretty noisy. If the engine has enough air to breath, the engine room won’t get hot. Hot air will reduce engine performance, so you want air to circulate in the engine room.
I repowered 3 years ago. The new engine together with new V-drive and drive train are much quieter than the old engine. At cruising speed, things are quiet enough for comfort.
Regards
Rich

To my recollection, about a case and a half.

Pete-
Did you insulate only the engine box and lid and upper panel, leaving
the space between engine and fuel tank open? How many 12 x 12 tiles
did it take?

My own post on replacing the sound insulation on my engine cover. I did not do anything but put in new 2″ insulation. Its much improved!
