You will be at -4 to -6 degrees on the struts .

. I’ve read a post or two on this forum to know you have been running Andy’s twin for awhile. I’m sure you know how to check your negative angle in relation to the points of Andy’s hull which should be level. But, to achieve -6 you would have to bend the tube upward and back down to get this and maintain prop depth. Is this what you have done? If so, I’m sure it is a short bend towards the back of your boat. Andy’s engines are usually mounted on 5 degrees and if you ran the shaft straight all the way to the prop , it would be very deep, that is why you have to reduce the angle to get the strut depth.

Dont think I can get the 5/6 degrees ski is already in place Is it worth the effort for the speed increase and stabiltiy???

The Negative strut angle with those props caused me to lose a Nationals, in the turns it caused the boat to drive its nose in an lift the ass so bad the boat spun on a couple of occassions i was leading at both times , i have experimented alot with these props an they do not impress me at all just cannot get the set up right , i believe the SGX is not designed to run these prop , you can still get the speed without using these props an all that negative angle ,good for straight line but not heat racing. Just my 1 cent Ace

As you stated its all about setup if you cant get it right then you will have to use something different no issues here with my Roadrunner Twins it can handle any prop I throw at it. Runs and turns perfect great for heat racing

Sorry to here that Ace I had similar problems at first . I ended up taking out the stinger through to compensate for the spin out or rudder through. It’s funny if you tested so much did you adjust in increments or did you just set it a what ever and went racing? Here something to try let off the throttle just before the turn and set the boat it should sling shot around the corner and also pull a tighter radius and accelerate a lot more. You got to remember when racing what anything can go into a corner at full speed and not crash lol!!!

John Brown a few years ago was spotting for me at the fall nationals and ask me the same question Do you ever let off!!! And at the time I didn’t it was all out or nothing I have faster shit know and I have to drive know plane and simple. Your shit is so fast it’s time to step up your game and go to the next level mate ;)

 

Also I didn’t loose my Winter Championship race pass ya later Charlie

Hi Jeff in experimenting with these new props at first had a little trouble with trying to just get the angle at the strut after finding a good angle I pulled the hole strut off the transom and bent the tube to accommodate the new strut angle to take the stress off the shaft tube.

Works fine and haven’t changed the strut depth. Have done this on two twins two 45s and one 90 like I have said -4 to -6 def is where I end up at with the ski -4 with out a ski -5 or -6.

Mr. Schafer sent the props. Tried them at half a deg. N. G..put heavy load on the engines and they quit immediaty. Spoke to Schafer he stated 1 to 2 deg is sufficeint

What he suggested is cut the middle of pad out so to get more adjustment. Got my 1667 finally runing with a bar cut and cutting the dog ears off reducing the load,

boats moving nicely . Rich b.
