Not to sound stupid , but what does it sound like? I am familiar with what valves rattling and pinging sound like when a motor is put under load but is this the same thing as detonation. Once again what does it sound like?

What you are familiar with as "pinging" is detonation or "pre-detonation".
Probably one of the worst things that can happen to an engine.

Sound is a really bad way to determine whether or not pre-detonation is occurring. Your motor can be experiencing "pinging" with little or no audible warning. Consistent and often spark plug checks is a much better way.
Well I dont have it going on then..... I took the boat out today for the first time this season and had what seemed to be a low tone burping sort of sound. through the exhaust every now and then.... no power loss or engine cutting out but definately a new noise.... No effect on performance though..... ran like a scalded dog!
Maybe a gas issue but I put 3/4 new in the tanks and only had maybe 2 gallons from last season < Nov > in there. what d you think?
