I have a 1988 2855 with a 460 OMC/ cobra outdrive. Engine and manifolds were new 10 years ago. It RW cooled. I feel that it's time to replace the manifolds and risers/gaskets. Only thing is, I can't locate anything for the 460 engine. Seems like everyone stopped making them. I know that they should be replaced. Anyone have the same experience, or any helpful info ? Thanks Joew

I have seen new manifolds for $1500 each - ouch! Not sure about the risers. Here is another possibility - http://www.manifoldwarehouse.com/mes...no=hge-460kclr , probably want to call them and find out what it takes to mate to the Y-pipe (or if it is a perfect fit). They claim it is a "OMC Ford 460 Manifold Conversion Kit". But, in the description is says the manifolds are for a 454 GM, so a call is definately recommended.
Well, sounds like it may not be the best solution - http://www.boatered.com/forum/topic.asp?TOPIC_ID=149262 . And this explains the 454 manifolds.
Or if you have 3 boat bucks laying around - http://www.cpperformance.com/p-14912...manifolds.aspx .

Joe, just curious, why do you want to replace the manifolds and risers?
