For folks who launch their boat with inboard via a ramp - do you block the exhaust outlet (say a tennis ball?) to prevent the chance that water backups up into the engine prior to starting, as the angle may put the entire exhaust system including the riser and back cylinder, below the waterline?
I think this needs to be a practice...but have never heard it discussed as such. Maybe I've just missed it...This picture reminded me.
