Thanks for the replies to my header question. Iam new to the whole jet boat world so some of my quetions might seem stupid to you guys but you gotta start some where. So here is another header question,the ones on my boat now flow water out as soon as you hook up the garden hose and turn it on,these are stock. After market ones seem too have diffrent setting when water comes out. Does this effect you engine temp or is this just a cooling method for you headers. Just dont understand this whole header water flow,seems to me your motor would run hotter with aftermarket headers.

wil a set of bassett twisted headers give a stock 460 bbf marine motor more power,or will it loose power?
