I purchased a Mercury 150 XR6 to replace the Mercury 125 I had. I have a Mercury Trophy Plus SS, 13.5" X 21 pitch prop I had on the 125. The company I bought the prop from said it would work fine on the 150. The boat dealer said I should have a Tempest SS because the Trophy had a small hub. So, who do I beleave?? I ahve an 18' Aluminum semi V boat, 1621 lbs total weight.<br /><br />Thank You,<br /><br />Rushin
