Re: [OMC-Boats] Horn and blower

As always Lee, thanks for the wealth of info. Ok, educate a first time
I/O owner on blower use. Mine does work, by the way. So does it need
to run at all times the engine is running? Or do I just run it a few
min before starting? And as long as you're in a question answering
mood, let me ask another newbie I/O question. What should my cold
start routine be? I've read on some boats, the trick is to move the
throttle to several times to prime it. But being as this boat is so
old and quirky, I wondered if it didn't have a completely different
procedure.
