needing some help...

[thormx11]

I have a 1987 Mercury 80hp outboard on my pontoon and i have recently noticed oil dripping from the water intake. I did some research and believe this would be the shift shaft seal. Does anyone know where I can find an impeller kit and a shift shaft seal for this model motor?

Also, changing the oil as I am typing this, Ive noticed water in the lower unit oil.

I live in western ky. I dont know much about boat engines, but im pretty good with a wrench, so i figure i'll give it a shot, I took a previous boat to the local boat mechanic and they charged me $400 just to clean/rebuild the 3 carbs on my engine, so I'm planning to start doing some of my own work on my boat, lol

Do youself a favor and buy a factory service manual for your specific engine. It saves time, frustration and you won't have to do the job twice.

Thanks alot, those links will help me a ton. I have not even found the s/n on this motor yet, my last motor had a tag on the side with s/n and model.

Re: needing some help...

seatched the motor up and down, couldnt find a disc like you have pictured, Ive found a few numbers stamped here and there, but nothing matched any of the other numbers.

Re: needing some help...

Also, To fix the oil coming from the raw water intake problem, I replace the shift shaft seal right? Is there another name for the shift shaft seal, because i cannot find one online.
