Setup for Vector with Bridgeport Randy, Let
me first thank you for offering your expertise to myself and all the other
boaters on this site trying to set-up their rigs. I have been an avid
power boater for the last 35 years and have always had a soft-spot for
Hydrostreams.... I
currently have a 1981 I purchased last year.... I have replaced the
rotten floor, reinforced the transom with additional knees. The boat was
already partially set-up as a drag-boat. It has opposing center steering
with dual cables, a hot-foot foot-throttle, turn-signal "type"
trim switch on the wheel and both the battery and fuel tank are to be mounted
behind the drivers-seat and placed in the center of the boat. I have
just purchased a 1986 2.4 Litre Mercury Bridgeport EFI racing motor.
I have both a manual and a hydraulic jackplate I can install on
the boat. My first question is which jackplate do you recommend I install,
secondly where should I have the engine height based on the pad of
the boat (as you know the engine already has a nose cone with low
water pick-ups to allow higher engine mounting heights...I
have been in a couple of Vectors and Vikings in the past and those
boats always seem to be prone to "chine-walking" once about
65-70mph was reached. Third...what
items can I have done to the engine to improve it's life and performance? Finally...what
type of prop can you recommend for my application..I am strictly looking
for top-speed..I have a 28 pitch big-eared Mercury chopper that I can
experiment with... Thank
you for your time... Sincerely,
You
sound like you’re going the right way with the set up and rigging. You
can start with the prop shaft ½” below and see how it takes a set. If
too high the engine will pull like it wants to make a right hand turn. The
chine walk is a function of you correcting the actions with steering
input. It won’t go away – you must control it. Try the chopper and get
some first impressions.
Please submit whatever questions you have to IHRTechTalk@yahoo.com. All questions and answers selected will be displayed on this page as they come in. Note: though all boaters are welcome, priority may be given to I.H.R. members. Randy can not be held responsible for any advice given. Though his information and expertise is second to none, he has no control over what you do with your boat. It is up to you to boat safely and act responsibly, and his advice is only to be used as a guidance for your high performance boat/motor of which you are the one responsible for the risks involved. Thanks,
