Viper with Modified 150
have a 77 viper its on a full restoration from top to bottom, front
to back. Its almost done but my question is?? I have put
together a 150 inline 6 it has a modified short shaft midsection (has
exhaust port like the v6 outboard offshore style) and it is
running a newer style 89 model foot with a nose cone. The
motor has been bored 15 over 2 ring pistons it has a twister lightweight
flywheel and it has some little tricks done to it. I stuck
this motor on my boat without a jackplate and the trim not hooked up with
the motor down it hits the transom so I need a set back. I
was wondering what should I use 5 in jackplate or solid setback and about
where should I set the height. This is a pleasure boat it will
never pull a skier just me and my son or some passengers. So I need
the best setup and prop size. Iím going for speed so I
can sacrifice the hole shot for top speeds so if you help me I would
be most thankful.
your props will work and give you some versatility. You may have to come
up with some custom plate of some sort. The exoticness of the motor will
warrant this. Coming up with one to work with the in line style of trim is
the hard part. Check www.hydrodynamics-usa.com.
