HELP!

I'm thinkin about buyin a used jet ski but the one Im lookin at is only 587cc's. Does anyone know if that's enough to pull up a wakeskater (175lbs.) or even on a dock start. If you have something similar, let me know.

the jetskis out now are well over 1000cc's...im just going by the GTX though i guesss...but thats what i use and that thing can rip someone out but struggles with fat people (250+)

ive gotten up behind 9.9 horse inflatables, and jets are more efficient than props.

satori*, I have been trying to ride behind a novurina with a 15 horsepower and still cannot even get it to dock start me

160 lbs, but the boat is so hard to plain off, plus his rope is to short, and I can get up on a boat so it isn't me

I already have a boat that'll pull me fine but, it's a pain to turn around a lot when tryin a new trick so i want the jet ski so we can take em both out and just party while someone ride behind the ski and like 9 ppl chill in our boat which we are totally rediong, check it out....

i know that my friends gtx wasnt too good for riding but i think it was a 97. i have my honda turbo 4stroke and its 1236cc and i swear it could pull 3riders up at once, it pulls two fine

satori*, jets are most certainly not more efficent than props,

and I think that jetski would struggle with pulling someone out, b/c my 750 standup wont do it, belive me we've tried, and I almost died in the process

I ride behind a 92 sea doo sp and it works fine, ask the dude if he'll pull you with it once? duh

kento911, jets arent as good at high torque, low rpm and low horsepower. but at high rpms jets turn out more thrust than prop engines. in the situation of getting up, if you had a prop and a jet at low power and size, but same size and power the prop would probably do better (although the physics of steering makes jets more manageable in this instance the prop would turn out more thrust), but in a larger motor higher power (still control) situation, its arguable that the ski would have more thrust. not to mention the fact that prop boats with larger horsepower need to be larger boats.
and the simple physics of the matter shows that jets derive more thrust per hp in that props inevitably cavitate and waste power and torque to that slippage.

im pretty sure this information is correct and makes sense. but regardless it is a bit of a tossup.

...satori has some isssues with admitting he is wrong, and will argue with u until u get so frustrated with him u just give up

... satori blah blah blah, wah wah wah.
shut up.

just because you're always wrong jacob, doesn't mean you have to say i have a problem with being wrong. if i'm wrong and i know it, i'll admit it. fortunately or not, there hasn't been an instance in which you were right and i was wrong. CAUSE YOU'RE A FOOL.

burnt

seriously, if you want to fight. lets go. put up your dukes

kento911,is on my profile

satori*, i have built jet boat and i have built prop boats and jets are definatly less efficient in almost every way, so throw all the physics u want because i am leaning on expierience and i am not going to argue with u on this one its proven fact ask any boat manufacturer.
