[QUOTE="Zum, post: 213555, member: 349"] I checked out what my slippages was for the first time,today. My boats a 1652 with alittle jet tunnel(hull). I have a 30hp mariner/yamaha(87),found out that it has a 1.71 gear ratio and only supposed to have a 4600 WOT rpm?(O.oh) The rpms have me alittle concerned as I run 2 different pitch props. With the 13,used 90% of the time...I get 5500rpm,about 29mph(gps)...gives me around a 26% slip. The 11 pitch ,rpms go up to 5650...around a 15% slip. I'll take the gps out today,it's been awhile. Can't beleive the WOT for my motor is only 4600rpm,also can't believe it hasn't blown up,it has been used..used. [/QUOTE]
