In most cases the old boat is tired or needs some major repairs but the motor is still strong. Many of the buyers have replaced their older motor in the recent past and some have rebuilt their older motors. The end desire is the same as they want to keep the motor and get a new Dyna-Ski Boat.
Sometimes customers have the motor swap done by their local dealer and sometimes we do the swapping. One time the new boat gets all new controls and gauges with the older engine and then again sometimes they keep all the original rigging. Each boat is different it seems. We always suggest new throttle and shift cables.
Most the new Dyna-Ski Boat owners want new hydraulic steering as many older boats did not have it. So the new Dyna-Ski is easier to drive and safer with nothing to wear out or need replacing with the steering system.
Another benefit is if down the road their motor needs replacement they have a newer boat to put it on. So once again the expense is spread out over many years. Most of the time only minimal updating of the controls and rigging should be needed unless you change the brand of outboard motor of course.
I have never heard of an inboard boat owner keeping the motor and getting a new boat but I could be wrong perhaps?
I got this off the Evinrude Website and thought it was interesting.
