Hello, folks.

I have a Bayliner Jazz with Mercury SportJet engine. The last time I had it
in the water, it would not start. I took it to a local boat shop, and they
replaced some sort of ignition module, and said it is fixed.

I can't get it to a lake just yet to give it a test. Is it safe to start
the motor just for a few seconds without water? I just want to verify that
it does indeed start.

Your help is always appreciated.

First off, no it isnt okay to run ANY out of the water even for a few seconds. There maybe a few that can stand it, but what Can and MAY happen is; For those with an outboard type unit, the water pump, which is rubber, being turned inside of the metal housing with no water for lubrication has its "ears" torn off. Now it wont pump water for squat. It wont hurt the engine to not have water cooling it for a few seconds.
Next would be the "jets". If they are using any type of Cutlass bearings, which are rubber sleeves inside a bronze tube, the same thing happens. Try getting your skin super clean with alcohol, then taking a metal rod and twisting it against your skin. Watch it grab your skin and try to lift it around the rod.
I have been working on jets since they first came to America (which was the Buhler) and outboards for almost as long.

Yes it does make one a bit curious. Or it does me at least
