I have a technical issue/question about my engine...... my engine is leaking oil out of the lower holes in the lower unit (behind the propellor). 99.9% it’s oil or residue from the engine (exhaust) and not from lower unit...... Do you know what it could be or heard a similar problem ? I’m checking my engine oil once in a while.....
I hope it is not the oil seal in the engine, but when it is or could be because you sell a lot of these parts please let me know.
And when the engine oil seal should be renewed maybe you can give an idea of the parts I need and should renew (because it’s clever) when taking out the uper unit (engine).

My writing is not perfect sorry for that.......

Greetings
