When we got our Honda
2000 we were excited to put the thing to use. On our boat, a Lagoon
, we placed the Honda
on the deck
, over the port side forward cabin
. Even though the exhaust
was fairly quite the resonance inside the hull
was really loud, too loud in fact. Then I noticed the feet were leaving black marks on the deck
. That's when I placed the Honda on a carpet sample to protect the deck. I instantly noticed the whole boat seemed a little quieter when the Honda was running. It was the carpet. Now I figured if maybe the genny was on something a little thicker then the carpet it would be quieter still. I found some leftover styrofoam packing from a new vhf radio
. I placed that under the genny and wow, a huge difference in sound both inside and out. Now you could actually spend time in the port hull
when the Honda was running. However, when filling the genny up, the gasoline that dribbled over the side was eating the styrofoam up. Had to come up with another material not so solvent in the presence of gas. Here's the styrofoam blocks...
I then tried a pool noodle. I took the noodle and cut it into 12 inch sections. Took those sections and cut them in half lengthwise. Placed 2 sections under the Honda and fired her up. Again, wow, what a difference! The whole boat got quieter still and you could barely feel the Honda running even when standing right next to it. I believe with the genny isolated from the hull the boat stopped acting like a huge resonance chamber. I could probably nap in the port hull now. Try it and see if this works for you if you have a genny you run on deck. Heck the noodles are cheap
and you probably have one laying around.
