Joking really,,,,as,,, If I did all the yearly maintenance suggested by the manufacturers of all the parts I'd never have time to go anywhere. My entire life would be spent on recommended maintenance.

I'm sure that somewhere it says that the elbow needs to be taken off each year and cleaned out. Yeah, I'm going to do that every year,,,, just after removing and maintaining the heat exchanger, heads, through hulls, electronics, generator, both manual and electric water pumps, engine hoses, transmission, and on and on and on.

Yeah, right.
