I bought a boat several years ago. The motor is I am guessing is a 78. I was told to get the #s off the welch pin. I did, but it does not follow the logic I have seen to identify the motor. The #s are 6R78B J4914924. Somebody stole the hood cowl and I am trying to replace it. If you know the what the motor is (hp & Yr), do you also know what hood cowls will fit it? I still take my kiddo fishing, but it is louder than heck. Any help will be greatly appreciated!
