Which Prop?

Which prop to go with on 1987 Supra Saltare?
Acme 541 13x12
Acme 543 13x11.5
Any advice?

Call ACME and ask them. Be prepared to answer questions like the following.
1. What is your intended use? Wakeboarding, skiing, cruising.
2. Engine size and hp and transmission gear ratio? Is the engine in good tune?
3. Current prop specs
4. Current Wide Open Throttle RPM and speed.
5. How much ballast you intend to run if any.

I went with the 541 & seemed to be a good choice the one time I ran it on my Salt. The 543 will sacrifice a little top end for more low end grunt (ballast?). I don't know about all ACME distributors, but JT @ Nettles Props will swap it out if you don't like it. The guys at ACME were very helpful in my selection.

I called ACME and he said to run either 543 or 541.
I called Ski DIM and he said to run 13x14 4 blade prop as the 13x12 will run to high of RPMS.
Any suggestions.?

if i had to guess i'd say i've got 541. either way i'm very happy with it. i bought from acme. nettles is local so they do my repairs when necessary.

acme will prob let you swap the prop if you don't like it...just don't ding it. mike said nettles will do the same.
