I think that the manufacturers will have done alot of work to ensure that an outboard will run at WOT and give a reasonable engine life, however to run constantly above WOT can only be asking for trouble. Note, if the weight of the boats load is increased then the the pitch of the prop should be reduced so the engine can again reach but not exceed WOT, this will provide the best performance and fuel consumption.
Exceeding WOT or overloading the boat so the engine doesn't reach WOT is only asking for trouble, stick to the engine manufacturers recommendations.
