1" below the pad. At this point the water pressure gauge starts to bounce a bit. The boat is STABLE!! One handed steering!

70.6 is all it had though. Do keep in mind that I am running an older OX66 lower unit which is 1.81 ratio, vs a HPDI lower which is 1.75 and can be raised higher.

Next spring I will block off my top holes in my lower...or find an HPDI. Not sure yet.

These numbers don't work I think...unless the lower is a 1.62 ratio?

Sure they do. Remember that Fury props are stiffer than other props. 24 is really a 25. The new lower units also have reduced slip. My analog tach reads 57-5900 rpms but I believe it’s reading 200 rpm low.
