Re: Universal 5416 exhaust riser
Use sch 40 pipe. Looks easy to cut and weld one up. Practical Boat Owner said any riser should rise at least 16 inches before any water gets injected. I prefer dry exhuasts . As one diesel mechanic said "If everyone went for dry exhaust and keel cooling, us mechanics would all be out of work."
