Going to winterize my boat this winter.  Do you guys Fog these engines?

i know it's a hot topic but I don't fog my engine and my local dealers do not do it either (I asked)

Indmar does not recommend applying fogging oil while the engine is running. The fogging oil could damage the catalytic converter. The cylinders must be protected by removing the spark plugs and applying the fogging oil directly into the cylinders. 3. After all the cylinders have been treated, crank the engine to spread the lubricant on the cylinder walls. Replace the spark plugs in the engine.

     This is from the Indmar manual for the Raptor 575. But to be honest, I have never used fogging oil and had a ski boat for 23 years (1800 hours) with no problem.
