Does anyone have experience with the 1.67 Transmission with "High Elevation" 16x12.5 prop?
This is our current selection but I am wondering if it is overkill as we are low elevation. We only surf and have no real need to go above 25mph at any time.
We will have 700lbs of lead and normally run a decent sized crew. Obviously looking to optimize performance for surfing but don't want to over do it
Would love everyone's thoughts.
We boat at 6000’ with 1.76 transmission and a 16x15, 900# of lead and have no issues. That was crew of 2, but I’m sure 5-6 more would matter much. The 16x13.9 might be a better option. I intend to pick up one and decide which I prefer.
The 1.76 is a welcome upgrade. If you only want to go no more than 25 mph then you won't care if you prop down to a 12.5"pitch, you'll have torque to spare, but, I don't think it is necessary. You can sport a 15" pitch prop, at a lower elevation with 4-5k lbs ballast and be fine. It is essentially a balance between speed and torque, finding that happy medium. I would not go over 15", other than that, it's a matter of preference.
The 16x13.9 is a prop Supra designed with acme specifically for the 1.76 trans.
It also replaces the 16x15 factory option.

I have the 3145- 16x13 prop. It is overkill at low elevation but at 6000+ with 10 people it is needed. 16x15 will be perfect at low elevation.
My understanding is the 16x13.9 pulls like a 13 and top ends like a 15.

It would be wonderful if you could get one. Wakemakers doesn’t list them. ACME is back ordered since early December.Quote:

I had to clear my cache to get updated page information. It’s in the cart now just waiting for authorization from the CFO. Thanks for waking me up to my mistake.Quote:

I'm going to do the same.
I don't need the extra torque really but it's always nice!
