I am putting together a 1978 Vector. I am going to be
rigging it with a Merc 2.4 pushing about 245hp at the propshaft.
This should be more than enough power for the boat! Currently the 25
gallon fuel tank is in the bow....should I keep it up there? I am
also looking for a prop that will give this boat great mid-range
acceleration, and I would be satisfied with a top speed of approximately
90mph....what do you suggest? The boat has a jack plate giving about
6 inches of setback. I debated putting the motor on the transom, but
this would have caused the propshaft to sit too low for optimum
Thanks,Tim Faught - Toronto, Canada
Vector with that power is an easy 90 plus. Put the motor on the transom
but in the fifth mount hole or all the way up. This puts the propshaft
about 1 1/2 inches below and the boat likes it. With a little more rudder
you'll have more steering and trim control. The boat will easily exceed
90. Put the tank or some tank in the tail. The more weight in the center
the better. Try not to put heavy items on far out points. Just about any
GOOD prop will work as the boat is pretty forgiving in this set up. If you
want to go 100 then it gets complicated.
Good luck and be safe with all that power.
