I bought a 2000 pontoon with an F115 four stroke that has been sitting for 2+ years, meter says 188 hours. Changed out the oil in engine and lower, new water pump impeller, fuel filters, new plugs, and of course drained the fuel and flushed with new fuel. It lit right off and doesn't bog when I blip the throttle with the prop in the water.

BUT I don't know what I am looking at with the multi-function gauge! Key-on, but not started, it has three of those bars across. When running, the middle one blinks. Everything that I can find online describes this model of gauge with Mode and Set buttons. This one does not have them.

I have also been told that what I'm looking at is an oil reservoir gauge setup for a 2 stroke. I did hear a brief alarm that I assumed was a low alarm on the first start after changing oil and filter.




Anyone know about these?

Just in case this helps another person, here is what I discovered:

Dip switches on the back are set for "2 stroke" so it's looking for oil level.
Oil pressure on 4 strokes like mine are "go/no-go" pressure switches.
Newer models have Mode and Set buttons, apparently mine is an antique.

The old 25' pontoon is up and running strong at a screaming 25 MPH @ 5800 WOT grin

Also make sure your Tach is set to 4 stroke.
