Which elbow needed to convert exhaust from loud to quiet

[njmedic3306]

My exhaust currently goes out the stern and is a bit loud. I see that there are caps on the pipes that go out to the prop. There are a lot of elbow that I see on ebay, any ideas on how I figure out which one will fit? Its a chevy 5.7 crate motor in a 1982 Scorpion 210. It looks like a 90 degree bend.


would this one have worked?

Measure the outlet of the riser on the exhaust manifold.

Most people pay big money to have through hull exhaust installed.

You want to get rid of it?

It looks like a 10 min project to convert it over. NONE of the elbows on ebay have any measurements. I would assume there is some standard distance from the riser to the outlets........

Nope,... There's Several y-pipes, Several risers,+ Several elbows to choose from,....
You might try lookin' em up in a Mercruiser on-line parts lookup, by the Serial # of the motor/ drive...
Or just go 'n measure what's there...
3" or 4" in,... 3" or 4" out, round or oval...

Maybe I was being a bit vague. I already know there are 4 inch diameter pipes. I am wondering about distance. I guess its worth it for $20 gamble since they are $70 a piece new. What confuses me is NONE of the websites I visited give length, so I guess that is a standard distance. I understand there is 3inch, 4inch, and 5 inch diameters.

Here is what I bought...
