Vengeance vs Black Max

[stubblejumper]

What can I expect as to a difference in performance between the Aluminum Black Max,and the stainless Vengeance?Would switching to the Vengeance change my maximum rpm?
My lund 1625 rebel with 75hp 4 stroke reaches 38mph at 5800rpm with two people in the boat with the 17" pitch Aluminum Black Max.I want a spare prop anyways,and I would like a more durable prop as well,so I am thinking about buying a Vengeance prop.However,when I tested the boat,there were only two of us,no gear,an empty live well and 3/4 tank of fuel.Being that I will have three people in the boat on occasion,and a full live well,I am thinking of going to a 16" Vengeance prop as a replacement.Do you think that the 16" Vengeance would be a good choice?

Re: Vengeance vs Black Max

My experience on a small light aluminum boat... The Vengeance is a faster prop by a one inch pitch compared to the Black Max with the same boat load.

Example... a 17" Black Max has a 16" Vengeance rpm, a 16" Black Max has a 15" Vengeance rpm and so forth.

My marine dealer let me run and compare new props to find the best setup. Maybe you could also. Rpm wasn't a set certain amount of difference between pitches. A 13" gained twice the rpm difference between a 14" and 15" for the Vengeance. Over time I ran six different props and now have a Black Max and Vengeance for this boat.

Re: Vengeance vs Black Max

a 17" Black Max has a 16" Vengeance rpm,

Thank you,that is what I was hoping to hear.The 17" Black Max seems to work well,but I can't find a 17"Vengeance,so I was hoping that a 16" Vengeance would not increase my rpm more than 200 rpm.If it keeps it at 5800rpm like the 17" Black Max with two people in the boat,it should still be well above 5000rpm with three people,or a full live well.Best of all,I can get a great deal on the 16" pitch Quicksilver Silverado which is supposedly the same as the Vengeance but much lower priced.
