I have an OPS 60 I am trying to get going, and noticed it has the carb in front, and exhaust out the back.. the carb just has a barb on it for fuel line.. I am thinking I am going to need a remote needle.. would this one work? even though it is for a .46? I am not worried about the mount part, just the size..

OK ... but where is the output shaft ?
There are some OPS and Picco engines that allow swapping front and back.

A .45 remote-needle is fine for your .60 , maybe you'll have to open it 1 more turn.
(or 2 ... to be on the save side)

output shaft is toward the exhaust.. I got it running, but the carb came loose and started sliding forward.. so I'll have to look into this and see if I can locktight it in place maybe.. I hope to get it wet soon...

OK, I finally got it wet!!! of course I got wet too!!!! had to wade after it in very cold muddy water.... motor was lean and died..... ran a x450 octura to start with, and was not enough prop... cavitated coming out, and ran out on topend very early... switched to a x455 and was much better. boat was running very flat, but still very fast, around 50 maybe... the motor was supposedly blueprinted, and came off a rigger of some sort.. was ran by Dennis Love, maybe u heard of him?? I was able to move the strut up some, and it was still running about half the boat in the water, and was faster.. this thing turns on a dime!!!
I have a few questions for the guru's:

1) what would be a good prop to run? (x455 seems pretty good)

2) how much nitro should I run? or should I say, how low could I go, and still run good? I had it out on 33%... was thinking of cutting back to around 10 or 20% once I get it dialed in, to save on $$$...

HendricX

For a OPS ...... not lower as 20% nitro.

Try a X452/3 , maybe it will pull a X455/3

If you found out what's best , talk to Gregg of Voodooprops.com or Chris of Dasboata.com
if they can offer you a better 'tweaked' prop.

thanks for the reply.. it turned that x455 real easy... I think I could go a little bigger, who knows? until u go too far... I'll stick with around 20- 25% then.
