I am running a 220 Hewescraft HT ET with a 150 Yamaha. I'm wondering if anyone is running a SS prop with this set-up. If you are I would like to know the brand and size and any performance figures you have, WOT rpms, etc.
I've got a 21' North River Seahawk with the Yamaha 150 (total weight ~4000 lbs) and have the 13-3/4x15 on it right now. Lousy performance. I have a 4-blade 14x17 SS and a 3-blade 14-1/4x17 aluminum waiting for me at home to try out this weekend. Will definitely let everone know what happens out there on the performance test.
I have the 22' Weldcraft ocean king with a Yamaha 150 & Solas 13 1/4" X 17 stainless prop. WOT at 6000 rpm's for 34.5 MPH. I was really expecting a little more from this set up. I am going to try a 15 1/4" x 15 black steel prop. as listed on the Weldcraft and the Yamaha performance data pages to see if it will get a little better top end and bring the RPM's down a little.
