Referring to this style and not the bullet shaped ones used in the front of the Johnsons that bobw mentioned…
I’m not sure of all the applications but according to MarineEngine I think the full round ones 203885, were originally used on Evinrudes for the sides of the hood.
The flat tops 304461, are shown for the rear of the hood of Johnsons, but I’ve seen just as many full ones back there. I know we’ve probably interchanged or added a short length of hose to lengthen the shorter ones if need be.
And then there’s a 1/2 size 203455, that was used on the inside top of the hood on smaller horse Evinrudes that would fit into the concave area of the recoil to help center or position the hood properly and kind of keep it in place.
