I have a 78 vulture and looking for some set up help. I have a bone stock 94 200 xri with a Bobs 200 1.87 gearcase running 75/76 on gps with a small hub 24" Trophy II turning 6800/6900 rpm. I have tried several Yamaha drag props a few Mazco RE3's a mercury cleaverand a couple Merc choppers all in the 24" to 26" range. Everything i do slows me down to the 71 to 73 range. I would like to see 80 with my boat without modifying the engine. Is there anyone out there familiar enough with this boat to help steer me in the right direction? I have a 5" hydraulic jackplate and have run anywhere from 3" below to 1" above and somewhere around 2" below the pad works the best. Thanks, Dwayne Laramore. Buna Tx.
