Oil gauge purpose

[rhager4059]

I have a 81 Ranger with a 87, 115 johnson. The boat has an oil pressure gauge that is not hooked up. My question is why does it have the gauge for a 2cyl engine.

Must have had a 4-stroke motor on it at some time in the past.

What is the model number on that '87 115hp?

I would guess that its a H2O pressure guage on the dash.

J115tlcim is the model no.

I'll guess the same thing. Someone installed an oil pressure gauge they had laying around and was going to use it as a water pressure gauge on the boat

I was wrong in saying oil gauge. I looked at it closer and all it says is pressure. What would this be for and where would the plastic line hook to

It is a H2O pressure gauge. The hose connects to a nipple on the block or teed into the tell tale. Rt. hand, true story...I promise.
