this is some good info,
thanks,Louie.

IMCO also makes the older style of SCX lower that is pointed on the front like a SC drive...they say that the pointed one is faster on some boats...and the rounded one is faster on others.

I have not tried the pointed nosed one...but the rounded nosed one is supposed to be an upgraded design.

I bought my rounded one used here on OSO and it was already blueprinted by wilson. I run it an inch higher than my sc lower, and lost about 2 miles an hour...but have absolute reliability.

Comparison of two IMCO SCX lowers:
You can get either lower with a choice of Bravo style or #6 style prop shafts.

CB-BLR,
Do you know which lower the DCB F-34 ran the best with?

Thanks,
Joel

Joel,

He ended up using the pointed lower...but did not truely give it a fair comparison as he ran the blunt nose with Maximus props only...and the Pointed nose lower with #6 props. He liked the #6 props better and did not want to switch propshafts back and forth to try each of the lowers with different props.

I have learned that the blunt nosed lower channels more water to the prop than a SC lower, and needs to be run about 1" higher in order to acheive similar slip numbers.

Hope all this helps,

Chris
