Setback

Setback??

What does this do to the boats handling,

I'm after trying to get bow lift on my cat not to much I hope ha
Running cleavers with virtually no set back at all.

Can any one help??

Thanks

Cleaver is stern lifting prop.
If you want bow lift QSS or Laser or Raker
There is a bit in Larbys build thread about Hospitality Inns mission and Props
I seem to remember
Don't think you want too much bow lift in a cat though !

Also one of the reasons for moving the engine back is to get the engine higher and reduce drag - this also reduces bow lift. As Big Dutch says try a Raker and if that doesn't do it you'll have to move some weight out of the front or get more radical.

i dont know if its relevent but if the boat you have is the ex hospitality inns it was desighned to have the engines on the sponsons ratherthan in the middle just a thought.maybe talk to geoff purves as he had it from new

What size are your cleavers! I have a handed pair of 14 x 28 Stainless spoonbill props that are off my Yam V6'S.
My Cougar used to run 14 x 28 cleavers, you are welcome to try my props/maybe as a swap for your cleavers if the size is right

It is indeed my old boat, I converted it back to twins on the sponsons years ago and it's still the same...

Never needed bow lift with me, she needs more speed and more trim. She drove with the nose right in until you got to 65+ at which point the natural lift takes over and it all works as it should.
She's running 5" setback manual lifters to allow me to use 20" mids (yam). I don't know what speed walby is running yet but it needs to be all but flat out, cat's won't cruise like monos, they just plow the nose until you're flying!
