larryd, wow did not relize that 1/4" could make that much diff. does each boat (same make same model) end up with a slightly different optimal x dimension?

all i know is i have a buddy with a newer 36 outlaw higher x 496's runs 4 blades nonlabbed, me 1999 with lower x 500 hps running labbed 3 blades ( cant run 4 blades) and we are pretty close to dead even. i have him by .2-.3 mph on gps ( and that could be a big gust of wind) we run neck and neck. that frustrates me.

I am going to try to put the shorties on this week and try it but it's a bit cold out there
so i will see what i can do.want to try them before i pull the motors!!!!!!!!
and larry i didn't mean anything when i said too high!!!!!!!!!!

yzbert

i will send you a coat.

baja36ft

why can't you run 4 blades? i do hydro's 26 pitch with hp500's at 74.8 gps

i would go 5 blades w/ the raised x and then test, test, test.....

yzbert

could not turn them, the threes just worked better. are you running salt? efi or carb?

baja36ft

salt water and yes carb!!!

yes each hull can be slightly different , but if the didn't change the bottom between yours and your buddy's they should be real close so you are right you should be very close to his x boat manufactures tend to be real conservative in thier x dimensions so you can definately go higher then they do and you can always space them back down , thy fact that you are using 3 blades does lead me to think your drives are too deep , unfortunately you just have try it good luck if you get them up you may not be able to get on plane with 3 blades

yz, how fast are you running now ?

I'm going to assume low 70's.

I have heard from more than 1 person
that the 496ho's ( performance wise)
run pretty close to the carbed Hp500's.

I don't know if that makes you feel any better though

Even though I love to spend other peoples money,
baja 36ft has offered to be the "guinea pig",
his results should be very compareable to what
you should see.

i run right at 70, last year the gods must have been right and i ran 73 once. make that 69.9 not 70. I would love 74.8. heck i would take 73 again. i hope that baja 36ft sees an improvement.
