Re: [OMC-Boats] Horn and blower

Here's my pre-start procedure:

1. While in line at the ramp, open the engine cover, remove stern tie downs, bow safety chain.

2. As get closer to it being my turn to launch, start blower, run at least a minute or two, with hatch open.

3. Back trailer and boat until trailer fender are submerged, hop in, lower drive, ensure gear is in neutral. If I'm by myself, I usually will unhook the boat from the winch before I hop in. The boat usually just stays on the trailer until you either physically lift the boat off or back out gently.

4. Keep blower running at idle if you're not moving. This is usually the time I move to the queue area and tie up, keeping her running. You can close the cover. Since you're not moving, air is not forced through the vents and out. Use the blower to do this. Once you're off, turn off the blower.

Always run the blower after the engine has been shut down. A minute or two is enough really, and again, opening the cover allows any slight but potential spark to escape.
