|
|
Big question for the day.. after trying to find these answers thru the various threads... I must be lacking in sight tools....
1. Is the 15" pitch for the SS HONDA Prop the better setup for a moderately loaded CD25 with twin 90s, refrig., a/c, and 'stuff' for CGAUX facility work?
2. What would be the expected WOT speed, on the flat?
Sea Angel is abt to hit here for rigging and I am looking to optimize the instrumentation and cruising effeciency. Moments of truth for the pocketbook are abt to hit.
Thanks in advance and 73s. _________________ Art ka1rx

We have the stock props (3x13.5x15) on our boat and would like to change to a 4 blade. Does any one with twin 90's have used other options. with this standard prop at WOT it runs about 5800 rpm's. Would like to increase our milage as we like to cruse at about 16-18 knots, 42-48rpm's
Any help would be greatly appreciated
Thanks,
