Karl, that is correct...there is no strut. At least not the way most people think about one. Actually this is the single biggest idea I had that led me to the weight reduction I was able to do on this boat. There is nothing adjustable on this boat; making things adjustable just adds weight.
My thoughts went kinda like this: Laying in bed one night thinking about how to go faster (you guys do that too I bet!) I realized that I never needed to adjust the strut height or angle on any of my SAW boats. Well, since I didn't need to adjust the strut, why have one at all...I would just support the stuffing box under the boat and solder some bigger tubing to the end to hold the bearings. Well, since I am not going to have a strut to mount to the transom (big weight savings!) why do I even need all that wood back there (more big weight savings!)? Well, if I don't need the transom to do anything (I can just mount the rudder to the side) why not just cut the whole back of the boat down and lose the transom AND part of the sides (yep, more big weight savings). Well, I don't have ANY idea what this new shape is going to do to the lift and aerodynamics, but I will worry about that later...this is only an exercise in getting rid of weight. Then I woke up and went to the shop and started work.
So that is part of how I got to where I am now, I am going to try to put some pictures on here...you will notice a few other areas that look kinda different (maybe a LOT different). It was ALL about weight...and it looks like it works really good. I have very high confidence that if I continue to run this boat it will go 80+...I am moving to the land of rough water though and I'm not sure how much I will ever run it again. I sure would like to set the timing equipment up one more time and bend on some props a little, oh well, I guess it will have to wait...
I will be happy to continue answering questions as you ask.
