I have a 81vector 2.4 225 it has lwp with a bobs convertible jack plate set at 2.5 offset running 1/2 below the pad the boat is set up with center steer dual nfb steering with turn singal trim and a hot foot I would like to know what y'all think would be a good all around prop and what would be a good drag racing prop for a 1000ft I was considering a 22 or 24 yamaha drag for when I want to run the 1000ft but before spending the money for a yamaha drag I would like to hear some opinions on what y'all think would be my best bet

I ran my first 1000ft event this year and tried out a borrowed virgin 24P Yamaha drag. Depending on how hard you want to twist that motor I'd think you'd be in the 24-26P range after its all said and done. My best of 3 passes was a 71.6 @ 7100rpm w/ the 24 Yammy. I normally don't turn my motor that hard but I was determined to get one good run that day. :mrgreen:

Your boat is a little heavier than mine but I'm running a full original interior and a 2.0 liter XR2 which is heavier than the 2.4...so I'm betting the two are pretty close in weight. I too am running a Bobs convertible @ 2.5" setback...and right at even with the pad. Assuming you are running a 1.78 (XR6 Case) or 1.87 gear, the 24-26 is where you want to be I'd think.....but never refuse an offer to try out different props! :up:

Jeff has it right, try as many props as you can get your hands on because there isn't a magic prop that does everything well.

I have only run 1/4 mile with my viper and love the 26 yamaha so if I were to run 1000 feet a 24 is where I would go first but don't forget about the et or a cut chopper either. If you can find good used props you can usually try them and resell if they don't work out for you, I myself have a hard time selling props for some reason and have accumulated quite a few in the last couple years.

For a good all around prop I'm still looking. I like the acceleration and hole shot of the 27srx but I like the cruising speed and top end of the 30 steve smith offshore cut. This summer I will be looking for a 29srx just to try it out.

Good luck on your quest.

Try a 28 Chopper for your "everyday" prop, should put you at about 90 mph. Most Vector guys like more setback, probably 6-8 inches, propshaft a little above the pad.

Well I have a 26 big ear chopper that is spun I need to get fixed I haven't had a chance to run it on the boat yet due to it being spun maybe it can be my ridding around prop and I also have a 31 hoss that I have only ran a few times that I think will be a good top end prop

When I send the 26 chopper off and get it fixed I am going to have the weed cuters taken off and I am up to having any other mods done to it if y'all have any ideas let me know

Well ran a 22 yamaha and I think it is to small only made a couple of passes and turned close to 8000k with hardly any trim got a buddy with a 24 going to run it next and I will let y'all know how it does the 22 scared me to many rpms didn't want to end my season before it got started may try the 22 a few more times and keep a real close eye on the tac I also have a 31 hoss that I only ran a few times last yr before I found a crack on it ready to get out there and see what kind of top end speeds I can get I got the 31 from a guy that was getting out of his vector could run it up to 94mph he says with a 2.4 200 merc so I sould be able to at least get that with my 2.4 225
