[Max Soto]

Steve,
Just in case, check this one out first....I don't have any comments, but It
might be worth to ask the owner about  this set up.

> Steve S,  The original Cat 38 design of heavy cast steel pipe fittings is a
> very poor design- to have all this vibrating weight cantilevered off the
> exhaust manifold, which is going to fail at a threaded pipe joint.  Catalina
> has redesigned the riser to an all welded fitting of stainless for a price
> about $200 (6 + years ago) as I remember.  I would give Catalina a call for
> price and bump that against a local fabrication shop.  The redesigned part
> is of very simple construction- schedule 40 ss pipe, with welded mitered 90
> degree bends, welded to a 3/8 ss plate (as I remember), which is bolted to
> the exhaust manifold.  The part weighed only about a 1/4 of the original
> design, with no threads to fail in fatigue.  My big problem was hooking up
> the "flexible" hose to the water muffler.  As your picture shows there is
> not much room allowed for the hose to clear the underside of the sail locker
> and enter hose fitting to the muffler.  I think mine was worse than what you
> have.  I ended up making a 45 degree attachment fitting out of epoxy/glass
> to solve that problem- which I still have the mold for if you or anyone else
> would like to borrow it.  This subject would be a good candidate for the
> MAINSHEET.
