OK, I know, enough already on the SV27! However, I ran mine today straight out of box with brand new DTx3800's. It is unbelievable to say the least. But hey, it doesnt take much to impress a newbee right? The hull had a bare minimum of water inside after a good 10 minute escapade. Now, I need to know how to adjust the prop angle pos/neg. I loosened the 2 screws on the side and it will not adjust up or down. Do I need to loosen the shaft (stuuffing box or whatever you call it)? Thanks
