they just don't build them like they used to
what would you say the cut off date would be for old Johnson vs. new Johnson?
eta: I have a 71 model

this is the stupidest thing i have ever seen. nitrous is a gas therefore can not be added to fuel. it would have to be installed with a kit not by just adding it to the fuel.
From my understanding the guys that used the additives said that they worked by breaking down into active nitrous compounds. Apparently the additives dilate the fuel lines allowing the Johnsons to have a more stiff and ridged response to the particular vessel.

Someone posted a picture here of an old Johnson wrapped in art deco colors couple weeks ago. Couldn't find it, may be on the soccer board by now.

That depends. If you have to choke it, it still falls under "new"

Bp,, my blood supply, i mean fuel supply, due to a couple of serious incidents has slowed down to my Johnson. The motor cowling doesn't seem to be as large as it once was even though it still seems to have same HP after warming up.. Could uv rays coupled with "fuel" supply alter the size of cowling?

FWIW petroleum based lubricants will freaking eat holes in outboard covers. Especially the ones made for Johnsons. The holes are small and hard to see but let me tell you the will let all kinds of things through those holes. Failure to use proper water based or silicone based lubricants and the associated cover failure has created thousands of little expensive problems. Most of which you never intended to call your own.

The other side of those holes is a rocky barren place.

Nah, cowling size is something you are essentially stuck with. You can try to have a skilled technician craft a larger cowling for you but I am told the process is VERY expensive and some what of a pain. As far as I know UV rays have nothing to do with making it larger. UV does in fact have deleterious effects on general covering materials though and Johnson coverings are no exception. Prolonged exposure without protection will indeed cause blemishes in the finish.

Uv rays made it smaller, not larger, coupled with fuel supply issues that tend to not go down as far as it once did when my Johnson was still a new model of less tha 60 years old, Boat Doctor.

My Johnson still performs essentially the same as when it was new but someone keeps moving my two tanks further and further from the Johnson as the years go by. I suspect gravity.

Have an evenrude doing the same thing. Let us know if you figure it out. It has been to the shop several times with no good results. You cant tell by running it on a hose. Even on the water it is hit and miss for acting up.
I have sprayed power tune in it years ago when I had a carbon build up problem and it did wonders. Maybe we need to try that.
