Thanks again for the responses. Yes I have read that bulletin and pretty much every other piece of info on the net relating to water ingestion! Given that we have only owned this boat for 10 years and it is the original engine I suppose I cannot rule out exhaust valve/s sticking as a possible cause. But I can confirm those flappers are an unreliable method of preventing water traveling back into the engine and I am looking at ANY other alternative.
