need more torque?

i've got a 6.5 honda "bored out" or whatever released did to them, 58t sprocket and torq a verter, 900' rope, and the released spool set on the middle diameter. my buddy is 6'6 220 and can't get up. i have plenty of top end right now when i'm riding. should i make the inner diameter smaller or larger, and do i need to add more rope? i have a spare 600' spool in the garage. appreciate it.

what is you inner diameter

it's at 6" right now. i can take it down to 4" or up to 8" i just don't know what the result will be either way or if i need more rope once i move it.

mojo, smaller diameter = more torque but less top speed and vice versa

you dont want to go any smaller than that.... i would get a bigger sprocket (68 or 72)

if you move down to 4 i dont think you will have enough speed for either of you

thanks. i guess i'll drop it down to 4". i guess i should think of it like a mountain bike gearing(since it helps me visualize). what will adding more rope to the smaller diameter do?

it will mean that the closer you get the the winch the diameter of your spool will be bigger and you will increase your speed a certain amount every wrap on the spool....

i really dont advise using a 4 in spool.... but its up to you

what would be the downside? right now it has the ability to pull me really really fast. are you saying it would make the speed to wishy washy? we are going to build a slide start, but can't use em everywhere. my buddy does ride a zariel and i swear it makes it harder to get him up

inconsistent speed and putting more strain on the engine... ive found you get much better pulls with larger spools .... i use a 8 in spool

large sprockets ftw

My friend is 220 and 6'3 and I can deepwater start him. I have a 6inch spoo,l 10/58 gear ratio with a 6.5 HP and a TAV. But he can only ride my old 116cm Hyperlite scape behind the winch. He has tried my 39 Byerly and 41 Cassette Transformer and he just cant get all the way on plane with those boards. But next time we are out we are gona have him try the 42 sst too see if it works, So Maybe he needs a bigger board Question

i guess i'll just build a slide start b/c i want one too. and i'll try the 8" diameter. i almost sold my winch a while back. so glad i didn't.

i wonder if new would make a 48 or something

would an 8hp engine solve the issue of a deep water start for bigger guys while still allowing not too much speed when they are up?
