I thought I would post some feed back as it might help someone else out. I think I found the prop for my boat. I have tried several, the last one a 19p aluminum that did not perform well at all. Slowest and poorest performing of them all. It was a Solas. The rpm's were in the right range, it just did not perform well for my Lund.
So I ordered a 4 blade SS 13x17 Solas HR Titan. This thing absolutely rocks on my boat. It lifted the stern out of the water great and as soon as that happened the boat just took off. Great handling, hole shot, top end was 41mph but the 41mph felt fast and nimble. RPM 6300-6400 and the blade stayed hooked up through tight turns and trimmed way up. Very happy with it. So if anyone else has a Lund Xplorer 1825 w/115 Merc 4 stroke or something similar I think you will be pleased, $279.00 shipped was my cost.
