Exhaust cover for 20H?

[Schiada]

I am working on a 20H and have a exhaust cover that needs a pipe or pipes?
Here is a photo of the housing. So,what did the pips/pipe look like?
The housing is a Quincy.

That doesn't need a pipe. That's the way you run it - open.

Their must be more? their are 2 bolt holes. It must mount ????

that went with that exhaust system. There was a cast aluminum cover that had raised fins on it like on an air cooled cylinder. For closed up quiet lake running where you had noise problems you ran with the cover on which was secured with two screws and the exhaust went down the tower housing as was intended. The place where the screws went is obvious.

When you wanted to wake everyone up or go to a race where noise was OK, you took it off by removing the two screws. The piece was made by Quincy as someone already stated, but to my knowledge it never came with pipes or had any type filler block with it that would allow pipes.

Gene East is the Quincy expert on this site and I am sure he will chime in.

ADD: Lots of guys used to have the waffle pattern of that cover burned into their upper biceps on the outside of the arm from letting their arm be where it should not be when carrying the boat out of the water.

Believe the item pre-dated the 20H and was originally marketed to the KG7H user. Complete and partial examples of this item show up on Ebay on a fairly regular basis. If noise police inhabit your lake then not worth the hassle.

Thanks!! I get it now.

Ed, the noise police are everywhere!!!!! "F" them if they can't take it! I will see you in JAIL!

Maybe I will build a pipe system so the sound is behind the boat?? Out the side?that would make me look to see if I was being passed?

Not much I can add that hasn't already been said.

Ed is correct, this manifold/stack/deflector (whatever you choose to call it) pre-dates the 20-H.

You'll notice the housing slopes downward to clear the integral fuel tank of the KG-4 and KG-7 Mercurys.

Quincy Welding sold hundreds of these during the early 1950s. More of them were installed on stock fishing motors than were ever fitted on racing motors.

As Bill said, the 2 mounting holes were for a plate that could be easily opened for noise or closed when the game warden or police were around.

All hot rodders remember uncapping "Lake Pipes" on their cars. Same principle!

I like to tell a story about my Dad; George William "Bill" East, concerning these exhaust adaptors.

Dad was deputy marshall in our home town of La Grange, MO, a small town just north of Quincy.

He received a call from an elderly woman complaining about 3 boys in racing boats making a lot of noise on the river and she wanted him to arrest them.

Dad responded with 3 reasons why he couldn't do that.

1. "I have no jurisdiction on the Mississippi River"!

2. "My boat isn't fast enough to catch them"!

3. "One of those boys is my son"!

Gene,that is too funny!

That makes me think maybe it is KG7 ? Will need to take a closer look.
That is a problem with a motor in a box.

That will fit most 2 cyl. Mercs. KG-4&7, MK-15,20,25. It will NOT fit the 22 or 30 ci Mercs or the real small 2 bangers.

Post a pix of your cyl. block and we can ID
