The SSM water pick up for this application is not any better than a stock unit pick is for a flat bottom with a jack plate. The water pick up on the twin pinion is out in front in the nose cone as viewed in the previous post. compared to the 75H pictured, which has the pickup just in front of the skeg. On the cabover hydro, with the engine tucked under and planeing on the gear case the pickups will be out of the water. It can be seen in the attached photo the nose cone is clear of the water on the 75H and the twin pinion will be more so. For that reason the turning fin/rudder has 2 water pickup tubes cast into it for speedo and engine cooling, like the inboard boys do. The adapter plate pictured has the water ports drilled into the back edge. The centered port is the input from the rudder which is rifle drilled through the rectangular port and into the divider.The rectangular port feeding the bottom of the block. At the front of the divider between the 2 pockets a hole is drilled into the rifle drilled hole to allow water into each pocket. The water will flow across each pocket to a port at each side of the adapter, one under the drill, to feed the water to the tubes that run cooling water along the forward side of the exhaust ports. The access hole on the under side of the plate will be capped. Kept trying to convince myself that I could run a water pump with water from the nose cone and feed thru the bottom. Not a good idea. I do not know how water even gets into the 75H. The skeg must push a wave in front of it and into the holes.
Added a couple of pics of the clamp bracket machining also.
