That's a great deal - I wish I had a boat that could use them.

What size hull, with what size motors would these work really well for?

Nathan.

Can you tell me the price for the 5518-3's including shipping to the Netherlands ???
Do you have a Paypal-account ???

55mm counter rotating props?? Gotta be for a 60"+ hull. I bought some 50mm for my 34" hull and they down even come close to fitting.

I contacted graill and he said they were a bit small for his 96" cat. So a 60" - 72" would be my guess. As to the motors - HUGE!

[Gerwin Brommer]

Yep, that's why I want the 3blades.
For my CT-03 on 10S2P on Plettenbergs 370/50's.

Does Prop Shop still not have a website?

[kookie_guy]

man those 5 blade props are sexy.

[Gerwin Brommer]

They sure look sexy, but like women : hard to handle.
You have to be gently with the throttle if you wanna slow down.............

Why, what happens if not?

[kookie_guy]

my first guess would be the rotational inertia would damage something. but I am probably wrong. lol

[Gerwin Brommer]

Because there are a lot of blades, there are a lot of blades in the water.
At least 2 blades and very likely even 3 !
More blades is more "brake".
Imagine what happens if you slow down with the throttle and the motors stop.
What if 1 side has 3 blades in the water and the other side has 2 blades in the water.......
The back of the boat can behave more nervous with 4 or 5 blade props.

They were purchased originally for a drifter xl with twin pletti 370/50/a1s's on 10s.
The calculations on the three bladers looked real, real nice, lol !
