Exhaust Riser Replacement

[karista]

About 3 weeks ago while motoring in 25-30 knt winds my Exhaust Riser failed, the entire section where the water nipple is welded into the tubing broke off. What a mess that made! I called Ken Roy at Catalina in Largo and he advised me that their metal shop is in California and that I need to return my old Riser to have a new one made.($290)
I shipped the old one back to California and Kent Nelson at Catalina CA had a new one made for me and ready for shipping back within 2 days of receiving my defective Riser, now that is great service.
I received the new Riser and was wondering whether it would make sense to coat the welded area with a high temperature grease or manifold paint to retard future corrosion in that area?

They probably rot from the inside.

Benrd : I've recommended numerous times, that you should put a "stake weld" on the inside and NOT use wire reinforced hose from the anti syphon to the inlet nipple. It's tooo stiff !!
If you had changed that hose to a nylon reinforced like I have recommended (back around 10 yrs ago) your old nipple weld may not have fractured !!  

If you haven't installed a hump hose - now is the time to do it!!   A few thoughts
