Help! We recently bought a 1996 Chris Craft Concept 17 'Fish n Ski'
boat. It has a 115 HP Outboard motor on it. I've had the motor fully
serviced.
Yesterday we were trying to pull a 140lb skier on it. The boat really
struggled to pull the skier out the water. We had two other people in
the boat - both weighing about 220lbs each. The gas tank was about 1/2
full.
If the boat is undersized or if its some technique that we are doing
wrong - - I'd appeciate the feedback.
Assuming all the mechanical stuff is up to snuff there are a number of
non mechanical things that can cause you problems. Two biggies are
weight distribution and motor trim.
A motor trimmed in will tend to force the bow up, trimmed out, down.
Trim and weight has to balance. IE Four hundred and forty pounds sitting
in the stern of the boat is going to want to force the boat's stern down
so you would want to trim the motor in to counter act the weight. Of
course, with that weight you may be at a point where the motor, even
trimmed in, is unable to overcome the weight. moving them forward would
help. The smaller the boat the more susceptible it is to weight and trim
effects.
Weight should be kept, as much as possible, on the center line and at
the mid point of the boat, then trim adjusted to take up the slack.
You'll have to experiment to see what works best so start small. As
light a load as possible with a skier and play with the variables. Note
what works best. Then work your way up in boat load, again noting what
works best for each situation.
