My manifolds and risers seem to be leaking a little and i would like to remove them to inspect their condition and replace the gaskets. Where can I buy the gaskets for oem indmar manifolds and risers, i can't seem to find them on skidim. The engine is a mastercraft rtp-1 (vortec 350). Also where can i get the mounting screws, can i replace them with stainless (the boat is used in salt and the stock ones are rusting). When i reinstal them how much do i torque them down?

You might try and call Skidim, they might actually have it even though it's not listed online. That, or you could probably call up the dealership and see if they would sell you what you need. <BR> <BR>Are these the ones you need: <BR><a href="http://www.perfprotech.com/store/catalog/Indmar-Marine-GM-Small-Block-V8-305350-Cu-In-Exhaust-System%2C2865.aspx" target="_blank">http://www.perfprotech.com/store/catalog/Indmar-Marine-GM-Small-Block-V8-305350-Cu-In-Exhaust-System,2865.aspx</a>
