Just a question on the low oil:
As long as the low oil pressure light did not come on, could the engine have been damaged by low sump oil?

Does the crank run or slosh in the oil bath created by the oil pan? If so, I could see where low oil level would be a problem.

beleive it or not Im brain farting on what the oil system is on the 2gm and my internet foo isnt working

I thought it was splash flow for the crank but I just cant remember or find what it is

having said that regarding oil level...always check after running...and let the oil settle(at least 5 minutes) and avoid overflowing

also make sure your case vent is venting...as it will avoid you squirting oil out the dipstick causes all sorts of messes

jajaja

My 3GM is an oil pressure system ( should be same as 2GM). The 3gm has an oil pressure switch- it is tied into an alarm light and buzzer. For the op check the low pressure alarm as well as high temp alarm (light and buzzer) both work.

I do keep my oil level up to the top end of the fill lines on the dip stick.

that idiot light though is a very rudimentary buzzer, how much pressure is what you would need to know...a good oil pressure gauge is worth it in my opinion

Your are right. I even bought a oil pressure sender and gauge. However there is a question on the yanmars as to if is is best to install a tee fitting so you have both pressure gauge and press switch (with buzzer and light). Once the Tee fitting is installed, the vibaration of the engine (and with the weight of the gauges/switches hanging off the end of the Tee fitting), there is greater likelyhood of the Tee fitting breaking or leaking. In the end, I have not installed the gauge because it seems it makes it much more likely to have an oil leak at the connections.
