Hello

I am selling my boat (the tuffy) and it seems like I have milky oil. A buyer asked about it and I, like a dummy, told him it was milky when I drained it a month ago. Well now he calls me and asks me to drop 4k on the price so he can get a brand new lower unit. I'm pretty sure everyone here can confirm its a load of BS. At minimum he says he wants the lower rebuilt and the "gears measured up"🤣. How the hell do you measure a gear??? Yes, you can measure backlash, but not the gear teeth...

Long story short, I got an OEM lower unit seal kit for 20 bucks. I'll throw that in, and then it should be ok right? Buddy is saying that it will blow up and needs a full blown rebuild... I just need something convincing to say to him... I feel like If I say I did it myself (ive done a few lower units before) he'll be really cheezed.

Also, what is an acceptable amount of play for the front prop shaft roller bearing? I can see the shaft move if I push it with my hand. Another Q. The OEM prop shaft bearing is $300. What is the accuracy spec on these? I could just measure the old one and go get an SKF at napa...

what did you get for $20?
I do not think you replaced all the seals and o rings for $20.

Did you pressure check the lower to see where the leak was, and pressure check it after the repair to see it it is fixed?

P/N is 25700-93J00. Google it. I was also really surprised that it was $20 at the dealer. I buy a lot of stuff at my dealer so they give me a deal when they can. I am making a pressure testing device right now, however I am fairly certain it is the shift shaft seal. It was all split and dried up last time I had the lower unit off, I don't even know if it seals at all.

Make folks that want to help do extra work to provide that help.
I'm sorry, I didn't mean to be extra trouble. I thought I had mentioned it was the suzuki, I think you can see it in my sig below, no? (suzuki df200)?

most people make it easy and post what motor they are taking about when they ask questions about it..
just because it may be one in a sig does not mean it is one of them

Some mobile platforms drop signatures as a speed/space considerations.

I think its also an option you can mark in your account settings to not load as well

So take it to a mechanic and have the lower resealed and pass the receipt with the sale. Tell the buyer to pound sand because he is trying to screw you. He will spend $400 on the reseal and pocket the $3600 he saved. Do not sell people like that anything you will never be rid of him!!!

Sounds like the deal, if there was any, has gone sour. Move on to the next deal with a fix LU. It will make for a much easier sale.

well, it didn't take me long to find the criminal...IMG_0006.JPG
Basically someone didn't drive the seals in all the way and this one was flopping loose on the driveshaft...

or they tried pumping gear lub in without removing the top screw.
causing pressure to build up inside and popping the seal out
