I've done that before in a 7.4 to 8.1s repower Paul. I only used the silicone hose at the exhaust ports, about a 3 foot section at each one. Much easier to install for sure. Thought it would help for that very reason. Whether it actually did or not I couldn't tell as I wasn't familiar with the vessel's harmonics prior to the repower. I'd say that it could only help.

Well, this project is moving along a little slower than I had hoped however I did get to resolve the clearance issue between the enclosure and the breather. With a Zip disk on my angle grinder, I notched the edge of the breather where the interference was.

Image

I then welded a #16 gauge steel plate over the opening. The weld looks a little nasty since couldn't dial my welder down far enough for such a thin gauge of sheet metal. What I had to do was manually pulse the trigger so not to blow holes in it.

Image

Again with the Zip disk, I trimmed off all of the excess metal. Then using a flap wheel in the angle grinder, I cleaned up the repaired area.

Image

Next, using JB Weld as spot putty I'll smooth out the repair and give it a new paint job.

More to follow.

Well I finally had the opportunity to head out to the marina today and finish this project. Below are pictures of the enclosure powder coated in white with the sound insulation installed and the rubber edging glued into place.

Image

Image

Below is the main sidewall section that gets screwed into place.

Image

Next is the removable sidewall section which latches into place for easy removal. This allows easy access to pumps and steering.

Image

The notch that was cut into the breather allows plenty of clearance between it and the enclosure.

Image


Lastly, these are pictures of the lid also in place with and without the floor in.

Image

Image

Now I can't wait until spring to see (or hear) if my efforts have paid off.

This is what the weather was like at the marina today. Cold, windy and snow.

Looks great Paul. I'm sure that'll do the trick to get rid of most of the noise. Let us know how it works in the Spring...we'll still be here!

Thanks gents. The off season is a perfect time for projects like this.

If you're considering this project for yourselves, I can tell that an enclosure this size cost less that $350 to build. This included having a fab shop cut & bend all of the sheet aluminum and also having a coatings shop do the powder coat. I did the fitting, assembly and insulation myself.

The genny engine is water cooled obviously. What cools the coil end ?

Air flow ( the cover is vented )

This is correct. Bottom of the enclosure is open except for a drip pan under the motor. The AC power generating end is air cooled and draws air from the bottom on the port side of a stringer and exhausts it downward on the starboard side of the same stringer. This prevents the air from short circuiting which might result in a heat problem. The back side of the enclosure also has an open section from top to bottom behind the motor which also provides ample ventilation.

Gotcha. I assumed you had it figured out Paul.

Well we're now starting Canadian holiday weekend on which I was planning to launch my boat for the season. I was hoping to post the results of how much difference the enclosure makes on reducing the generator noise. I was also looking forward to trying out the new helm seat, steering wheel and Morse controls that were installed thru the winter. Had an appointment with a specialist yesterday and just like that I'm heading into surgery on Wednesday. The boat is heading for indoor storage. (%#*^% :shock: ?*$!! :( ) I should only be sidelined from work for a few weeks but looks like the boat may have to wait until next year.

Thanks for the well wishes. I'm sure that I'll be spending some time on this site during recovery.
