Thanks for bringing this thread uo.

Have a 26ST in the family . stock engine 5.7 alphas. Great boat for our lake.

My question is , is the 23” merc cleaver still the best prop for this ? After all these years, is that even possible ?

Any significant increase in power and you will need to upgrade the drives.
The Spyder is an awesome boat for its size in the rough stuff

Depends on how much rpm the engines can spin, but I would guess a little better than 70 with a light load and small chop to free up the hull

If it has 1.47 ratio, which is most likely. If conditions are perfect my guess is 72-73.
I have no idea what you mean by 1" spacer.
