Hi guys, going through a search for our next boat and have a question regarding the exhaust schedules on boats used in the NE. There are many good looking examples in the CT, NY, NJ area. I know in the southern brine people replace manifolds/risers every 3-5 years. Does that schedule hold up in the NE even when the boat is pulled for the winters? I can't find a definitive answer as to whether the colder water and shorter season have much of an affect. Obviously this will vary boat to boat, just looking for a general idea so I can factor the parts into the cost before getting serious about anything.
