Vegas Needs Speed I just took my newly purchased 87 Vegas xt w 220 laser efi w quicksilver 28 " prop w 4" setback on jackplate out on the water for the first time. Top end with me alone was 76 mph with 6500 rpm. Add 3 kids and could only get up to 66-70. What could be the problem? Is the quicksilver prop a dog? Bow lift ok by myself but could use more with load. Engine height didn't make much difference whether high or low. Any way to get excessive steering torque to ease up? Any suggestions would be greatly appreciated. Thanks Greg
Greg:
First rule of thumb, if you have excessive torque of the steering wheel,
your engine height is too high. You need to lower it probably a couple of
inches based on your description of the problem. It is possible that that
particular propeller or your gearcase shape has been altered and is wrong.
Usually a Vegas with a 28 Chopper with the propshaft centerline, 2 - 2 1/4
inch below the pad, will run a strong 80 and carry your passengers at 76.
It sounds like your problem revolves around lift. Check the pad and make
sure it is flat and does not have a hook in it. All these things,
(excessive height, untrue bottom, poor propeller or gearcase) could
contribute to your problem. You are not that far off, so I would say it
would be one of the above.
