This is the smaller exhaust cowl that fits under the bottom cowl It came off my 1968 mercury 350 35 hp outboard The only thing this motor needed was coils and points it has very low hours the motor is in excellent shape took to long to sell it so I parted it out already sold the controls and fly wheel other than that keep checking for parts I am putting up. If you need a part email me though ebay tell me what you need and I will let you know when I'm putting it up so you could grab it , I will not sell out of ebay. Thanks for looking
