Hey guys, went and checked on my boat today and noticed a little bit of what appeared to be engine oil on the top of the transom where the motor is bolted on. I have my engine tilted fully out of the water and immediately thought it was coming from inside the engine cowling. After investigating more and proving it wasn't coming from the inside the engine compartment, I began looking elsewhere. After tilting the motor fully up out of the water again and looking at the underside of the engine compartment I could see where the drive shaft comes down out of the engine? I took a photo so not sure if this is where the crankshaft seal is just guessing, hopefully someone can recognize this from the photo, give me some advice on a way ahead. I am keeping my fingers crossed that a full engine disassembly is not required to get at this seal, I do have the shop manual and will be looking through it tonight, just wanted to prod the members here for any advice.
The photo doesn't show oil leaking, but that is where I found a bubble of oil on the shaft, and after running the motor for 5 mins and tilting the engine up fully it was beginning to show signs of leakage.
the motor is a 2005 Mercury 115hp four stroke EFI.
thanks,
