Oil leak from engine plug?

[jcote75]

Hello everyone,

I have a m25xp and it started to leak from a few place during my last vacation.

oil sensor unit, now the engine plug between starter and alternator and i think from the starter (probably rear seal)

i did two thing wrong in the start of the season. First wrong oil grade (10w40) and oil ovefilled (probably 3/16 inch above full on dipstick)

i did change the grade to 10w30 and lowered the oil little bit underneath the full line.

i do have less leak bit still seapage a bit.

do you think this would resolve by itself or i probably will have some big work to do this.

here is the picture of the engine plug...

Not loosing a lot of oil. A few drop in the bridge after a few hours

many thanks for your help
Joce

I don't know how cold the temperatures get up there before you haul out for the winter but it seems your oil is a bit thin and might facilitate leaks. I would recommend 15W40. Check with others in your area with similarly aged boats to see what oil they are using.
