I know the prop options in 2020 for the 400/1.76 was a 16x17 and 16x15, looks like there is a new option 16x13.9
Anyone running the ACME 3591 16x13.9? Sounds like an absolute stump puller.

I run the 16x15 on my 400 with 1.76 and it does fine fully loaded and tops out at 38.
The 13.9 assuming the same prop slip would only drop the top speed to 35 and would likely be significantly torquier down low.
Seems like a good option to me.
35 top speed is plenty, I will order the 16x13.9
The fastest I go is wakeboard speeds 22-23mph

@Shoebox what's your drive ratio?
I'm 1.76 : 1 and run about 3200-3400 at surf speed on the 16x15 prop full ballast
That’s nice and low for Rpm’s
