I changed those cables on my engine once, it took a few hours to do it but it was because I took my time and was doing it solo. Another thing to check is the shaft that the forward/reverse cable controls, its hard to see it because of the parts that cover it but they are known to go bad. Basically, the way is works is the cable is connected to a plate, that plate is welded onto a shaft and that shaft goes into the engine and when it moves forward or back it engages the engine. Apparently, the weld that holds the plate to the shaft is known to fail after a while because of the pressure that it put on it.

I forgot to ask earlier, but are you able to rev the engine if you push forward or back on the throttle? If its revs but does not engage its safe to say its the cable or the shaft.
