I realize that and agree 100%
But ask yourself this question.
Why can't they come up with a material Lightweight and give the same performance as sounddown ?
I removed the pieces of sounddown from the inside of my old engine box (am planning to make a new box from Nicacore)
Time is short and still plenty left to do if I hope to be in the water 1st week of june so a new Nidacore engine box will be made up when I have time (working on a design to incorporate tackle station, storage and seating ) so I cut the old plywood box down in height from 18 inches high to 12 so far (waiting on word for custom exhaust elbow so I can get the box height down lower)
Those pieces of sounddown I removed (they will be reused) are friggin heavy !!!
I'm going to give this a shot as I have nothing to loose other than a few gallons of resin & a bit of Matt.
Will put pieces of SoundDown aside for later use ( don't want to cut up the SoundDown smaller.
The old engine is going into a dumpster once I make a new one out of Nidacore.
Will be a lot easier using the old box to figure out the design for the new one also.
I would think Nidacore panels got to have some sound deading advantage over 3/4 plywood.
Anyone agree ?
