Time for a better prop than the OEM 3 blade alum prop that came on my 2000 188 Fish&Ski. Here's the info...<br />Length 18'<br />Beam 8'<br />Motor Mercury 4.3L 190HP<br />Current prop 14x23 alum<br />top RPM around 4500-4600<br />Manufacture recommend top RPM 4400-4800<br />top spped around 46 (based on in dash gage)<br />Manufacture est top speed 50-52<br /><br />The Prop Shop of Cedar Falls Iowa (any feedback on this store would also be nice) has recommended the Turbo 2+2 4 blade prop with 14-1/4x20. The guy says he has put this prop on the same boat as what I have for people that do mostly tubing and sking and had great results. My dealers says not to get a 4 blade but then said he really doesn't have much experience with them. The guy selling the prop says that this prop should get me around 4600RPM at WOT.<br /><br />I do mostly tubing and sking and would like any feedback that I can get.<br /><br />Thanks,<br />Carl
