Thanks to all who answered my last post. I am still having trouble reconciling the hardware pacement with Ken's drawings. The plans locate the shaft hole 36" forward of the transom. After locating the rudder as far aft as possible and placing the strut in a position where the prop can be pulled without dropping the rudder, the farthest aft that I can locate the shaft hole is 41" forward of the transom.
Ken's drawing does not leave enough room for pulling the prop,( only about 2" from end of shaft to rudder leading edge). Should I sacrifice ease of pulling the prop to locate the shaft hole in accordance with the plans or move everything forward as much as 5" as long as everything will fit in the given space?

Thanks

Another option would be to drop the rudder, if and when, you need to pull the prop. Some people pull their rudder every time they leave the water.

Possibly someone who has built the Barrelback will chime in.

Few things in the world measure up to the thrill and satisfaction of boating in a boat that you built.

Perhaps your strut has a too flat shaft angle. Your engine should be on or aft of the CB. With the strut as fas aft as possible, & with engine on Cb, then you find a strut angle to match.
the exact location of the shaft hole I wouldnt worry about.

Set the rudder as far back as you can. The strut does need to be set for prop removal. set the engine as low and at or back of the CB as you can get it, like Ken said. The hole goes in between. It doesn't matter the exact dimension.

Setting the engine low usually mean notching a frame. But, a little lower means a lot back.

Kens,you're correct. The strut on the plans is a 20 degree angle and the strut I have is 16 degrees. I can shim the strut but will I run into problems mounting the engine at that angle even with a carb shim plate? I am close to the correct engine position with the 16 degrees but there is very little clearance between the shaft coupling and the shaft log. Do I need a full 4" between the shaft end and the rudder if my prop has a 2 3/8" hub to pull the prop without dropping the rudder?

Dan,

It is very important that the rudder be *under* the boat.
The engine should go where the plans say because it will effect the balance/trim.

The prop should have proper clearance to the hull and the rudder. I think it is important that you can get it off w/o taking the boat apart. Also - I'm not sure if there is a minimum recommended prop/rudder gap to prevent cavitation.

My rule is don't break the rules.

If you need to get a different strut to connect the dots between the output shaft and the prop - you should do that. The hole to be drilled will present itself when you put the engine/prop/rudder in their correct locations.

Good luck

It sounds like you should get a different strut. Try this; get a common 2x6 and use it to simulate your keel, layout the frames from transom to amidships. You can drill it for the rudder, strut, backing plates, etc. This way you can see the location of the hardware, and relocate stuff if need be.
