I don't mean to sound like a broken record here, but I just recently purchased a 82 Vector with a 200HP Johnson.
It's a 78 model crossflow with a 20 inch hydromechanical gearcase.
The boat has a CMC jackplate with 5 -1/2 inches of setback. Your recommendations to most of the people on this subject is to remove the jackplate. Does the same hold true for me?
Do you recommend a nosecone or not?
I currently have two props that came with the boat. ( 14.50x21 three blade - 14x26 three blade )
Are these sufficient or do you think something else would be better , and what kind of speed should I expect.
Thanks a bunch,
First off, make sure that your boat has dual steering. Most 82 Vectors did not come with this. The '78 200 has about the same amount of hp as the newer 175's. It should work very good on your Vector. I would probably try to run it with the jackplate, but I think the overall handling would be better without it. This is only true because Vectors are very sensitive to tail weight. The boat was designed around a 300 lb. inline 6 Merc. So now, we have a 400 lb. V6 and we moved it 6 inches back. You can see that our center of gravity is very one-sided. The boat's mid-speed handling, is very affected by this balance. Most Vectors with jackplates porpoise excessively especially at speeds below wide open. The gearcase that you have should be good to speeds into the 80's and I would not use a nosecone at this time. I am guessing that your 14 x 26 prop is a Merc chopper, and this would work very well on this setup. If that is the prop that you have, you should be able to run in the mid 70's right off the bat. With a little practice, I would say you would be approaching 80. Just make sure you run with a foot throttle, dual steering and solid motor mounts just to be safe.
