I have a bare aluminum sprint boat hull that I have going to be using for rivers and pleasure boating. Alot of the rivers that I will be using it on are shallow and full of silt and gravel so I decided to put a Hamilton 2stage pump in it. I would like to get all the room I can inside the boat so I was thinking of setting back the pump and engine. These boats are usually run with multistage axial flow pumps like the hamilton but the have the weight of the engine centered and a skeg towards the front of the keel to aid in quick turning (supposedly up to 3-7G's) I really have no use for that kind of performance in the corners but at the same time I dont want to ruin the ride. How far back can I safely set the pump and engine back in a boat this small? (13.5')
Here is a video of a very similar boat.
and a video of more what I am planning on doing with it.
their boats are 2' shorter and have smaller engines and I wont be quite so extreme I do plan on hitting some rocks and skidding across a little gravel.
Any ideas would be appreciated, Matt.
