I have a 1970 Donzi ski sporter 16 that came with a set of Holman Moody Manifolds to put on it. The previous owner said they were supposed to be the originals. They bolt right up to my Holman Moody 302 that is in the boat but the risers are definitely wrong for my application. They angle straight down and there is no chance of me being able to make any kind of bends to bring them around and connect them to the current exhaust ports in the hull there is just no space.
Really all I need is if I unbolt the riser section and just run the pipe straight out it will perfectly meet up with the current exhaust ports in my hull.
The boat will never sit in the water so I'm not concerned with not having a riser section but I'm not sure where I can find the part I need if anyone can guide me.
