NEED HELP ON PROP SIZE AND LENGTH OF PIPE

[haq]

I have an eagle 45 SG with .67 CMB greenhead Andy Brown's black pipe. Can anyone recommand me the right size of prop for this eagle 45 sg with .67 CMB greenhead. What is the length of the pipe should be? Is there any adjustment need to do for this eagle 45 sg? I am using 3/16 flex shaft. Is this ok?

thanks

John

Really not enough tank for CMB67 but good for S.A.W set up measure AB pipe 11.75 inches and start Oct 1460 then change 1462 Good Luck!

Allen thanks for information, I have Octura 1655 sharp and balance. will this 1655 prop works? if prop is correct and the length of pipe right, how fast will this boat run. What is mph for this boat?

Those props all seem pretty small to me....I can pull those with a Mac 45......

I would think you could pull an H-38 or H-30 with a CMB 67.....pitched around 5"....1667 as well....pipe around 11"....

Should go 80 mph..... :blink:

3/16" is too small by todays standards for 67's.....It will work, but if the boat hops, waves, etc, it will stress it and break eventually.....A 1655 is a 40 size prop. You could probably run FAI fuel with the 67 and turn that prop.....

No problem on 3/16 flex use small to 1465 max If you use 1655 great run but little of bit slow and won't torn shaft . If u want to get fast 1957 or 2160 Good luck!

Good luck keeping it on the water with a .67 in it. That boat is a Rocket ship

with a .45 in it. The tank size is a big factor too. Yesterday I ran my .67 EagleSGX

with a .45 tank in it, as I forgot my fuel tank, and got only 5 laps before it was

empty.

Thanks for information,

Now, I have to sell this motor and buy 45 CMB. I am eagles collector. I love the speed of an eagle. I have all sizes of eagles, running from .21 to 80. I am looking to buy 90 eagle sg or twin

thanks
