agreed Andy that you should have heard a very disturbing sound come from the coupler if the driveshaft splines were stripping the teeth in the coupler....since you did not hear this god awful noise maybe you just spun the rubber in the coupler....that would certainly be a less expensive situation to correct since the driveshaft should still be OK...
is it possible that the pitch on your prop is to high?....if you have too high of prop pitch and you try to accelerate hard from a dead stop it could be the engine is overpowering the coupler hub in its effort to move the boat quickly making the coupler hub break loose....
when things are running well can your engine reach its proper WOT range?.....if not the prop pitch may be too high as one possible reason....

I will investigate that as soon as I'm able to run it up to WOT. Prop is 14.5d 19p 4 blade so I'm fairly sure that isn't too high but I will double check for WOT rpm which I believe for my 230da 5.7L Mercruiser is 4200 - 4600
