New question to an old topic 4 blade props
Posted: Wed Nov 20, 2013 8:54 pm
I am considering having a cup put into the new 4 blade props I put on this season. They are 17X14's. Does anyone have any thoughts how much of a cup I may want? The boat ran well this season, but I feel the props could have been slightly better. They seemed much better than my 16X16 3blades, but again seemed to me I could go a little further on the cup and get a little more out of her at 3100 rpms. I did pick up about 2 knots already at that RPM.
She really comes up to RPM's fast and takes a little to build the speed. No struggle for the engines at all, used to have much more struggle with the 3 blades. Any comments would be appreciated. They head to the shop on Friday.
