These two struts anchor your exhaust and are a must for large boats.

When you go offshore in a large boat at planing speeds and you hit rough water, chances are your fiberglass hull will flex. Even boats built with thick, solid glass hulls will flex and that together with the G-forces involved can cause you big trouble. One of the most vulnerable pieces of equipment in your engine room under these conditions is your exhaust system at its joint with your turbo. Unless you have a double bracket and a “three-point” connection, your exhaust could move and separate just enough from the turbo to cause an expensive repair.
