| Prop & Gearing Question for Ski Boat Just Learning about boats... On a inboard direct drive 21 to 24 foot ski/wakeboard boat, what is typical prop size & gearing? I'm thinking about a 300 HP small block boat that goes 50 mph or so.  |

| With 300HP in the 50 mph range your looking at 1.0 to 1.5 Gearing, depending on max rpm. If Minimum load, total weight and RPM were known, exact Prop, size and Pitch could be given, as well as gear recommendations. Prop Dia will probably be 13 - 14+ depending on gear and weight. Jango |
