Here's one online for $150, though I've never worked with this vendor.

here's an ebay auction mislisting a V-8 manifold as this part:

> Ref # 8 - Part No. 312149 : "CAP, Exhaust, manifold, -stbd" &

about $45 shipped on ebay (in Canada, so more to get it to the US)

or $32 from that same place.

I don't see the elbow available, but you can get it as part of a V-8
exhaust manifold for $120 on ebay:

I'm sure you can find one cheaper if you look around a little more.

boats.net has all these parts new as well: (prices appear to be MSRP)
http://www.boats.net/parts/detail/omc/O-0380995.html $253
http://www.boats.net/parts/detail/omc/O-0312149.html $63
http://www.boats.net/parts/detail/johnson/B-0312151.html $168

I think Great Lakes Marine (GLM) might sell aftermarket versions of all
this new.

Here's the entire drivetrain for a boat like yours that failed to sell for
$650:

It looks like it has the 231 cubic inch V-6 engine instead of the 225 that
you have, but I think the exhaust manifolds are compatible.

If you look around through junkyards, you can probably get a much better
deal - I wouldn't be surprised if you found the whole thing as a unit for
$100-200.

Be sure to get a new gasket with whatever you get.
