Let’s assume for a second that I don’t know much about boats

What is this circled port for? It weeps some oily/milky water when the motor is run with the muffs. Do I have a problem?

For reference: 90ish Mercury 3cyl. 75HP

Not much help. I looked at my 135 merc and there is nothing in that area. Is it threaded?

Meelosh · Jun 17, 2018

No sir. No threads.

That is what's called a "weep hole". They are there to let you know when you have a leak.

If you are seeing oil come out of it, it is doing it's job. You need to replace the seal at the top of your lower unit.

BTW, that prop looks a little rough. You been grinding on it? Something with that much leading edge issues could be out of balance. That is hard on seals, bearings, etc.

Meelosh · Jun 17, 2018

No grinding on the prop. It’s just what you get when you don’t have a lot of money to spend on a boat.

Thanks for the info Allen. Next project I guess.

Yeah, sorry man. This isn't that expensive of a task for a do-it-yourselfer, but it does take a little time.

Be careful when dropping that lower unit. There are like six ball bearings in there that will bounce across your garage floor.

Oil/Milky water is always bad. Not always a difficult or expensive fix, but always an indicator that a fix is required.

This is the kind of advice that I love. It doesn't apply to me, but this is the kind of "watch out for..." that really helps a guy out.

Thanks Allen.

Yeah, I once had a late 80s Mariner, 75 hp. And I went in there not knowing. Thankfully, I had a magnet that helped me round up those damn loose steel balls. Needless to say, I was woefully unprepared for the initial discovery.

Except in vocabulary, I always seem to have the perfect words for when things go wrong.

I’m debating if I want to tackle it myself. One shop quoted me ~$60 in parts and ~$350 in labor. Which all seems fair. So I just need to weight the risk/reward of my son learning some new colorful words that I will have to explain at daycare.

pay the repair shop and be done with it.

May want to get rid of the #riverfisherprop
aluminum in good shape will be a nice upgrade. Won’t cost much

I had milky oil come out of one of boats I use to own. It wasn't too hard of a fix to put on new seals and I'm not too mechanically inclined.

Meelosh · Jun 18, 2018

Damn it. I was warned about boats. A hole in the water you throw money in to.

Thanks for all the advice folks.
