Some time ago I had inquired about a genset for my 2859. After all the helpful suggestions, I settled on two Honda 2000 which hook together to put our 4000 kw. The generators, which are mounted on the swim platform, supply enough for everything in the boat ie: A/C; two burners on electric stove; AC lighting; and battery charger. Fuel burn time is approximately 8.5 hours per/tank (one gal) on a hot Florida night (80*).
I built a weather and sound shield out of an old Dock Box which has worked well. I reinforced the drop down doors with 3/8" marine ply and glued a waterproof sound absorbing material to the inside. With the padding and the sound going out the stern of the boat, the generator noise inside the cabine and on the aft cockpit area is at a whisper. I also added the same padding between the dock box and swim platform and in the inside bottom of the dock box which all but completely obsorbs all vibration.
I have added pictures of this project to help anyone interested, to understand the construction and design of this project. It works great for us.

Very nice! I have thought of using the two Yamaha equivalent gens we have on our 2855. Are those removable ports on the sides to allow them to breathe/exhaust? Have you run them for long enough to determine if they will stay cool enough while the box is closed?

Thanx for the comment; I always run these with the side ports open. The ports actually draw in cool air and all the exhaust goes out the aft since the drop-down doors allow the generators to be placed to that all the exhaust goes out away from the aft of the boat. I never run the gens with these doors closed; and yes, the generators do stay cool.
Upon start-up you might hear a small engine noise at 50ft., however when they are up and running, at 50ft, you wont hear anythink. Inside the cabin is just a light purrrr with no vibration to speak of. If your on the aft cockpit, you will hear them, however you can carry on a conversation without ever having to raise your voice level.
