I'm still looking for a test wheel for my 1995 Johnson 200hp. I can't even find a part number reference. Any help is appreciated.
What is the shallowest pitched aluminum prop you can find at a marine dealer that has been in business for decades and has a wall full of used props and a box full of thrust washers. How about a 4 blade aluminum of shallow pitch and you cut 2 opposing blades off at the root? Or more difficult, find a used 3 bade alum. and cut off the blades half way or so.....just make it a point to get the modification as even as possible.......one way of doing that would be to cut one blade in half and use it as a pattern for cutting the other two.
I've seen test wheels dealers used decades ago where they had a huge tank where they ran engines to full RPM to check performance after a repair. It was basically a disc of suitable diameter to fit the engine under test, with several slits around the circumference where the material was bent out to catch some water.
