GNODDY Posted May 17, 2011 Report Share Posted May 17, 2011 Hey Guys, I just dropped the oil on my 40Hp EFI after 10 hours. I'm a bit scared but I don't have any experience with semi syn 25W40 outboard oil. The color is funny kind of a greenish brown. I have a pic but can't seem to upload it.

Roy Posted May 17, 2011 Report Share Posted May 17, 2011 I don't understand your problem, it's always been that colour. Link to comment Share on other sites More sharing options...
irishfield Posted May 17, 2011 Report Share Posted May 17, 2011 Was it the 25W40 "blend". Sounds about right.. mine ends up a bit more on the black side thanks to the Supercharger. If I'm not mistaken I also have a couple gallons in the hangar, unopened, as I switched to the Verado specific mix they came out with a couple years ago.

GNODDY Posted May 17, 2011 Author Report Share Posted May 17, 2011 Here's a pic fellas. Wayne I was hoping you would pop in and comment on this. Link to comment Share on other sites More sharing options...
irishfield Posted May 17, 2011 Report Share Posted May 17, 2011 (edited) Hard to tell from this far away... but that looks like it has water in it. Are those little bubbles around the top ? Edited May 17, 2011 by irishfield Link to comment Share on other sites More sharing options...
GNODDY Posted May 17, 2011 Author Report Share Posted May 17, 2011 Yes it is the semi syn blend. Link to comment Share on other sites More sharing options...
irishfield Posted May 17, 2011 Report Share Posted May 17, 2011 I'll pour some in a pop bottle tomorrow and take a similar picture for comparison. Link to comment Share on other sites More sharing options...

vinnimon Posted May 17, 2011 Report Share Posted May 17, 2011 Here's a pic fellas. Wayne I was hoping you would pop in and comment on this. I use the same oil and it does not look like that. The milky colour in the oil is an indicator of water/moisture. The only time ive seen this is when I rebuilt my engine and using engine assembly lube.

GNODDY Posted May 17, 2011 Author Report Share Posted May 17, 2011 Vinnimon this is the first oil drop since manufacture there is only 10hrs on it Link to comment Share on other sites More sharing options...
John Bacon Posted May 17, 2011 Report Share Posted May 17, 2011 Check the gaskets on your drain screws. One of the screws on mine didn't have a gasket. Link to comment Share on other sites More sharing options...
irishfield Posted May 17, 2011 Report Share Posted May 17, 2011 (edited) This is oil from his engine John.. not the lower unit. If he's got water in the engine oil... head gasket or the cowling filled with rain (or lake) water above the dipstick hole.

spincast Posted May 17, 2011 Report Share Posted May 17, 2011 The guys on this board have a wealth of knowledge - Wayne and Vinnimon especially, along with some others when it comes to motors, but if you only have 10 hours on it, dont you think it would be a better approach to take this to the place you bought if from and ask them? If its under warranty it shouldnt cost you a thing - and you can ask them for their opinion in writing. Link to comment Share on other sites More sharing options...
GNODDY Posted May 17, 2011 Author Report Share Posted May 17, 2011 Spincast I will be in touch with the dealer this morning but my heart was falling apart when I dropped the oil last night LOL and the dealer wasn't open for me to call. I'm going to also be giving them a call this morning. G Link to comment Share on other sites More sharing options...
irishfield Posted May 17, 2011 Report Share Posted May 17, 2011 Sorry Geoff... I guess I took that oil up to the lake.. so no sample/picture. Link to comment Share on other sites More sharing options...
glen Posted May 17, 2011 Report Share Posted May 17, 2011 "I just dropped the oil on my 40Hp EFI after 10 hours" On some new motors they may have a brake-in additive in with the oil. This may be what you are seeing. On new motors the oil doesn't change colour very much the first few times you change them. Let that bottle sit and see if anything(water or other) separates. I would guess you are ok. Call the dealer. Link to comment Share on other sites More sharing options...
spincast Posted May 17, 2011 Report Share Posted May 17, 2011 I hear ya on that count Gnoddy it - hope there is no issues and if there are the dealer takes quick action for ya, before the long weekend arrives. Link to comment Share on other sites More sharing options...
Fisherman Posted May 17, 2011 Report Share Posted May 17, 2011 (edited) Apart from it looking like liquid baby poop, I wonder if it's not condensation mixed with the oil. Some 4 strokes seen to have a bad habit of "making oil" from running at low speed and not burning off the moisture. I hope that's just recent and didn't sit in the engine all winter.

GNODDY Posted May 18, 2011 Author Report Share Posted May 18, 2011 (edited) Spoke with the dealer today and the first thing he asked when seeing this pic was Were you trolling for longer than 2 or 3 hours. Apparently this is common in motors with less than 10 hrs and with trolling. He asked if I dropped it I said yes he said alright run it this weekend and continue to check for my own piece of mind but he didn't seem all that concerned. This was the marine mechanic he also asked where I was as soon as I said quinte he said yup that's what's happened the water being so cold and the long run time it's put condensation in the oil.

GNODDY Posted May 18, 2011 Author Report Share Posted May 18, 2011 (edited) Here's a good read on oils and 4 stroke outboards. This is exactly how the dealer explained it. Has nothing to do with break in as my motor was already past the break in stages as per the break in process I followed fro The manual. http://forums.iboats.com/showthread.php?t=158085&page=1 Edited May 18, 2011 by GNODDY Link to comment Share on other sites More sharing options...
Fisherman Posted May 18, 2011 Report Share Posted May 18, 2011 Well I was right then, it's not burning off the condensation. Last thing after fishing or trolling, I'm usually about 3-4 km off shore and run the motor at about 2/3 to 3/4 throttle, that warms it enough to prevent that problem.

Tybo Posted May 19, 2011 Report Share Posted May 19, 2011 Condensation in 10 hours. Must have a tropical rain forest growing in there. Link to comment Share on other sites More sharing options...
