Default SB Exhaust manifolds

Does anyone have any idea what these are?

They came off of a 350 out of a boat that all the guy knows.



Trying to figure out if their worth buying and trying to find another set, I'm not even sure if they will work in my boat or not

Thanks

some old jet boat something. 40 year old aluminum. no design work went into them. they are just a straight line minimal size exhaust that you need to fab elbows to run them. worth about 85 cents a pound these days...

depending on ur app, set up and waterline that exhaust could be very well prone to water reversion. so just call them engine killers for now.

Looks like an old jet boat or old ski boat inboard with a direct drive app those were used on.

Gotcha, they would be going in a formula 242 I figured they would need modified to get them to fit but if its not worth it I won't even mess with them. I don't even know where I would find another set at

Should I tell him they really are only good for scrap? I would think to the right person they would be worth something

he is trying to sell them. don't tell him anything. he will either be insulted, or think you are stupid or think you want them cheaper. if he is a friend you need to be diplomatic about why you don't want them. a matching set to replace with later or for the other engine if twins is a good excuse.
