octura props

[RobertWurster]

Its been a while and i forgot is it the x or m series that dont have lift.I need new props for my sp 20.Thanx

 

[Jeff Barnhart]

x series don't make any lift, good place to start.

 

[RaceMechaniX]

M series are an X series with reduced tongue. Both are very low lift.

Boaters,

All propellers have a certain amount of lift in their design.

The amount of blade area in the propeller design and blade profile

and of course the pitch ratio all have a lot more to do with the amount

Of lift in each propeller.

The M-series have the least amount of lift in them.

The X-series still have more blade area than the M-series though.

Robert the 1400 series or M-series is a good place to start with

your Sport 21 Hydro. 1440 B/C, X-442, or a M-440 would be a good place

to start.

Happy Holidays,

Mark Sholund

Thana guys after the new year ill hit you up for some props Mark.

Wil a 1450 prop work on a sp 20?

 

[Kevin Krogness]

Thats probably too much all the props mark mentioned are where you want to start. The m440 on mine seemed to be the fastest but no lift and the hull pushed and made it hard to turn.

The 437/3 blade was easiest to drive turned easy but the 1440 b/c has been the best so far...
