Re: Thumper, EMI, or Kodiak
are you going to see salt water?
the two others you might want to consider are imco power flows and stainless marine.
if going salwater, stainless marine anodized and coated are probably the most durable by reputation, folllowed by the emi and imco powerflow anodized / coated. the imco will make a little bit more power than the others (based on a local bulders dyno testing).
soooo if you want performance, imco, then emi, similar price range, both good products,
if you want durability (and decent preformance), stainless marine.
those are all in the 2-3 grand range,
the others are cheaper and probably in the same range performance wise. I know that imco products have always been well made as have emi. don't think you could go wrong with either... imho
