Rib Unlimited 600 with Mercury 100hp fourstroke, what propeller?

[kvenios]

What propeller would you suggest for this combination of rib and engine?

if it helps i have a 13x19 on a 5.6m with a mariner 100 EFI 4 stroke. it goes upto just under 50mph and 5700rpm.

i'll keep an eye on this thread-i want to change to a diff prop myself as the standard one has a few light dings in it.

cheers

Now I have a Black Max Mercury aluminum propeller 13”X 19” and I go up to 34.5 knots (38mph) and 5400rpm. The engine has a gear case ratio of 2.33:1.

What do you think about 4 blade prop “TURBO 2+2 X” 13 ¼” diameter and 23 pitch? It comes also with 13 ¾ “ diameter.

Do you have a pic of the boat on a trailer when you can see the engine and the prop together with the hull?

Why? This combination must be faster...

What is the weight of the boat?

I think it may be a tad over propped...

I had the same boat with a 60hp Mercury 4 stroke and it did 38 GPS knots with 1 person and a full tank of petrol. It is a very effective and light boat that should be really fast with 100hp in combination with the right propeller.
