I discovered a persistent oil sensor alarm after I let the oil get low on my 1986 Mariner 75hp with oil injection and resevoir.

After refilling the resevoir, the alarm would not go off so I researched and subsequently suspected I had a defective sensor. Ohm test confirmed problem.

I cut the resevoir side open and removed the float and magnet after seeing that is was indeed separate from the float.

I have reattached the magnet to the float using hi-temp RTV gasket and sealed the 'flap' I cut in the side of the tank with similar gasket material, a 'patch' to hold the gasket material in place and a few stainless steel screws.

My worry is that the screws may get hot and melt the surrounding plastic. Is there significant heat along side the plastic resevoir?

( pictures show the flap I cut to get at the float, the repair 'patch' as well as a view from inside the tank before replacing the float)

This is how far I got with my attempt to repair the oil level sensor float. I fired it up with the water muffs on and it is all good for now.
