Slow Vegas XT
I have a 1985 Vegas XT with a 2001yamaha 200 HPDI v max /Bobs nose
cone & land & sea jack plate. I have tried chopper props/ Raker
props & torque shift props. Nothing seems to get the boat above 65 mph
& at that point the boat chine walks very bad because of over
trimming. I am very frustrated any help would be much appreciated.
the new Yamaha outboards have the most hideous gearcases for the Vegas.
Adding a cone just made it longer and added to the problem (they are also
5+" is diameter, so they blow a big hole in the water). I did a
Vegas like yours with the same basic motor a few years ago. With a 27 Pro
series Yamaha prop it ran 75ish. With an old '88 excel gearcase it went
almost 80. Put the propshaft at 2" below the pad and don't mess with
it. Then don't try to drive through the chinewalk. You can't. The faster
you go, the more it will walk. There is no cure, but just learn the
steering corrections to control the walk. Drive up to the point but not
past it and master it at that speed. Then, move to a new speed and
master that. It's like riding a bike, once you learn you'll never forget
and you won't think about it. It will just happen naturally. Also if you
have the Yamaha trim indicator only trim to 4 on the gauge. "5"
is for later.
