What ever you do dont buy a Milodon marine pan for a 460 its not designed to work on forward facing engines.

Ran one on Moo with no problems. Only issue was it WAS a little tight to the hull in the front, but so was the Ford Racing front sump that came out of the boat, which is weird, but that engine sits VERY low in the boat. JE pump and was designed for a low profile engine cover...

I haven't seen many jet boats where the engine is so low mounted, either, so I think it's a non-issue. If you got an inch of clearance, any of 'em will fit, Milodon included.
Moo's going with a Dooley this time around for that reason, and the fact that I had one, and then will have 2 Milodons for the twin jet boat...
