since your in Naples, going to assume salt water. Aluminum exhaust is not recommended for salt water unless you have a full closed cooling system.

In Salt, you just have to change your manifolds every 3-5 years.

that would assume that the boat is moored if its trailered and flushed after every use it would be ok surly???/

also lucky you, here in australia manifolds and risers is a $2000.00 (V6 or V8) plus job and then add labour

so you really want to get as much life out of them as you can
