mike rousseau Posted September 22, 2012 Report Share Posted September 22, 2012 Well that didn't take long... 2 months and i have an issue with my new yamaha outboard... But this isnt yamahas fault... I had a buddy who I won't name (member here) get caught in my prop while trolling... And I wasn't aware due to the fact that I was helping the other guy on the boat land a walleye... So the motor was in forward for about a minut with line in the prop... And when I did my 100 hour oil changes today my gear oil was milky... So it would seem my oil seals on the prop shaft have been damaged... Is this something I can fix myself... Or is this something I should get a pro to fix...? Let's say 1-10 scale... 10 being a really tricky job... Thanks Link to comment Share on other sites More sharing options...
misfish Posted September 22, 2012 Report Share Posted September 22, 2012 (edited) Why was Ron trolling so close to the prop? LOL J/K Spend the bill,and get it done right. Peace of mind. Are you sure the fill holes are sealed/tighen, properly? Edited September 22, 2012 by Misfish Link to comment Share on other sites More sharing options...

SBCregal Posted September 22, 2012 Report Share Posted September 22, 2012 tight enough to maybe squish out any seal/o-ring that was on there? Link to comment Share on other sites More sharing options...

That doesnt seem right to me... Link to comment Share on other sites More sharing options...
Fishing4Tails Posted September 22, 2012 Report Share Posted September 22, 2012 Put new gear oil .. Check after a few trips .. If it still milky get one to check it .. Best before freeze up . Link to comment Share on other sites More sharing options...

irishfield Posted September 22, 2012 Report Share Posted September 22, 2012 Did you pull the prop and look for any line sticking out of the shaft seal? Link to comment Share on other sites More sharing options...
glen Posted September 23, 2012 Report Share Posted September 23, 2012 Make sure you put the cotterpin back in. Link to comment Share on other sites More sharing options...
mike rousseau Posted September 23, 2012 Author Report Share Posted September 23, 2012 (edited) Did you pull the prop and look for any line sticking out of the shaft seal? Pulled it and everything looked perfect... Seals appeared to be in great shape... The line that wrapped the prop the day it happened was 20lb mono and I got the whole leader back out imidiatly... I had hoped that the larger diameter of the 20lb mone wouldn't cause damage... Edited September 23, 2012 by Mike Rousseau Link to comment Share on other sites More sharing options...
strik Posted September 23, 2012 Report Share Posted September 23, 2012 Let's say 1-10 scale... 10 being a really tricky job... If you need to ask... On a new eng and the amount you use it i would go pro Good luck Link to comment Share on other sites More sharing options...
Skipper D Posted September 23, 2012 Report Share Posted September 23, 2012 Well i know am not the one who trolled close to the porp ..... lol , I would ask the dealer Mike why the oil in your new motor lower unit is milky with only 100 hr on it . I can't see the oil get that milky that fast with no line stuck in the prop . Link to comment Share on other sites More sharing options...
danc Posted September 23, 2012 Report Share Posted September 23, 2012 After 30 years of owning a boat, I've never changed my bottom end oil without it being a little "milky". Never has it caused me a problem. Link to comment Share on other sites More sharing options...
Viking Posted September 23, 2012 Report Share Posted September 23, 2012 I would, as suggested change the oil and take it out, then check it again. I wouldn't assume shaft seal though. I'd pressure test lower end to find leak. Link to comment Share on other sites More sharing options...
Handlebarz Posted September 23, 2012 Report Share Posted September 23, 2012 (edited) I would bring it in have them look at it or question them why it might be milky and not talk about the line. Maybe the breakin oil breaks Down in some form like that??? I do remember some one asking about the difference in the original oil and stuff you use after the breakin period. But I have never bought brand new. Edited September 23, 2012 by Mike P. Link to comment Share on other sites More sharing options...
Billy Bob Posted September 23, 2012 Report Share Posted September 23, 2012 You need to see evidence of WATER in the oil...not just a milky oil.... Just put a leakage test on it.....bet it doesn't fail it. Link to comment Share on other sites More sharing options...
F7Firecat Posted September 23, 2012 Report Share Posted September 23, 2012 I had an evinrude that when I changed it would always appear milky, brought it in they pressure tested it passed with flying colours......go figure never had a problem with the lower end but did change the oil religously regardless Link to comment Share on other sites More sharing options...
bigbuck Posted September 23, 2012 Report Share Posted September 23, 2012 Take it in and get it pressure tested. Don't mess around. That lower end is 5 grand. Link to comment Share on other sites More sharing options...
4x4bassin Posted September 23, 2012 Report Share Posted September 23, 2012 I'm no expert but I can't see #20 mono getting wrapped into the prop for that short of time damaging your seals , I have had #50 PP braid wrap up with no damage . Also maybe your drain/fill plugs were tightened to much thus damaging gaskets ! If I were you I would take it in and get it tested just to be safe , way too much money invested at this point on a brand new engine to screw around !

Sinker Posted September 23, 2012 Report Share Posted September 23, 2012 Did you drain it after running it? What I mean is, did you use the engine, then get home and drain it? A lot of times, if you check it after using it, the oil will appear milky, but if you check it after sitting over night it will be clear. I would drain it, fill it back up, run it for a while, but only check it after its been sitting over night. I bet it comes out clear again. S.

mike rousseau Posted September 23, 2012 Author Report Share Posted September 23, 2012 It sat for 12 hours before I drained it... I put fresh oil in and I'm gunna run it and drain again and see Link to comment Share on other sites More sharing options...
jimmer Posted September 24, 2012 Report Share Posted September 24, 2012 Definitely bring it back to the dealer and ask why the lower unit oil is milky on a new motor. No way that line should have caused a leak. There could be a bad seal installed or a bad washer on one of the plugs. Link to comment Share on other sites More sharing options...
NAW Posted September 24, 2012 Report Share Posted September 24, 2012 So your advising me to to run another 150 hours on my brand spanking new outboard with water getting in the lower unit? Leak tests only take a few minutes. Well worth the effort. Hey, are you really going to fish 150 hours before end of the season. What's that, 2 months. 75 hours a month. That's almost 20 hours a week. Busy guy! Link to comment Share on other sites More sharing options...
