after having a discussion with a fellow member about the downside of having the exhaust flapper in the bellows of a 280 outdrive, i decided to try to retrofit a 290 flapper to my 280 drive. using an old 290 flapper to make a pattern, i cut the flapper from 1/8" sheet rubber, drilled the screw/relief holes in the rubber, cut to size, then clamped in place to test fit. appears to fit perfectly. using the retaining plates for a drill guide, i drill the holes in the cav plate of the outdrive, attach with #6x 1/2" stainless sheet metal screws. and wallah!:prod no more flappers in the bellows. thanks, rick!

It's funny, Rick was trying to sell me on this same idea. He did actually, just couldn't find the part.

Let me ask you, where did you get the parts and what was to cost. The job doesn't seem tough... did it go easily?

gilligan, i got the old torn flapper with the ss retainers from rick. made a lexan pattern from the old flapper. the retainers could be made from a strip of ss. didn't cost me a dime, as i had everything on hand. nascarians, just give me a shout whenever. i know how that goes. sometimes there is no such thing as a happy medium. would like to talk to you about a boat name.
