Mounting engine room equipment over Soundown
The new Yanmar 4JH4E is now sitting in the cockpit ready to be installed.
All the ancillary equipment, water heater, water lift, strainers, compressor and pumps are mounted. Now I have to face one last challenge. The engine compartment is lined with Soundown and all openings are gasketted but I still have lots of wires, hoses and filters to install before the engine goes in. How do I mount the wire looms and hose carriers over the Soundown without destroying its insulation properties? -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

Glenn,
The only answer to this I have seen is studs. For commercial marine use, there are 2 types available. One is adhesive and the other is weldable. In both cases, they are installed before the insulation and the insulation is applied over the top puncturing the insulation, then the head is threaded on to the stud and there are different types of heads. The studs are sound transmitters so the part extending beyound the soundproofing must be insulated as well. Check with your local ship chandlers in your area. If you have no luck, let me know and I will source some for you. Steve "Glenn Ashmore" wrote in message news:5tO%e.29124$hp.18702@lakeread08...

You can install little standoffs that protrude through the insulation. It's going to be tricky now that the insulation is in place. If you can, pick one side of the compartment to mess up and keep the other sides pristine. If I was in your position, I'd use a row of little fiberglass "U" shaped standoffs, screw or glass one side of the "U" to the compartment, the bottom of the U protrudes through the insulation, and the other face is available for fastening. There are commercial cable trays etc. but they are bulky, and being steel or aluminum, tend to transmit sound better than GRP. Or run everything in one upper corner of the compartment?

What I did when installing the engine in my Rhodes "Traveler" was epoxy fir
blocks to the bulkhead and then cut the insulation to fit. Noise will travel through the blocks, but I couldn't figure another way to do it and it worked out without much engine noise below decks.

I don't think you will loose too much sound dampening by installing a few
attachment points but you probably should try to minimize the number. Perhaps install two hangers along the top at one side and then suspend as much as possible from them. Also, attach stuff to the engine using standoffs. "Glenn Ashmore" wrote in message news:5tO%e.29124$hp.18702@lakeread08... The new Yanmar 4JH4E is now sitting in the cockpit ready to be installed.
