I was looking around the E-TEC 90-HP outboard motor. What are the thee blue hoses on the starboard side used for? --Steve

Steve, I think you are referring to the oil lines. They appear to be a kind of deep blue due to the tint of the oil.
jimh posted 02-12-2007 07:56 PM ET (US)
The oil lines on the E-TEC motors are a translucent tubing that has a blue tint to it. I am not sure if the lines are blue or they become blue from the oil in them.
You can see them in

in the picture with the caption "Port Forward."

Ahh, a mystery that only an E-TEC owner can solve. Someday, Jim, someday?
The oil appears brown inside the internal reservoir and bulk container, but blue/green when spilled on the white reservoir or in the oil tubes. Air bubbles inside the oil lines, visible only after shipping and prior to the initial start up procedure, are clear.

The oil feed lines and the oil recirculation lines are a Kevlar reinforced tubing that has a blue tint to it.
The 2 lines with plastic check valves on the stb. side and one line on the port side are the oil recirculation lines that feed puddled oil from one cylinder to another and to the main bearings. It is normal to see bubbles in them.

Once the motor is used, the oil in those lines is brown. I believe that those are scavenger lines that recirculate oil not burned in the power generation and lubrication process.
The liquid in them is blue from the factory. This is probably done to show that the motor and system has been primed.
XD-100 oil is a honey color, so I'm not sure what the liquid lubricant is from the factory - it may be a special formula.

Those must be the nitrous lines.

BOB,
that is the funniest thing i have heard!!!!!!!!!! LOL
like my friends race car.
Jim,
if you daw i have designated the oil lines on the starboard side, not the "port foward" as you have posted. the lines on the port side are clearly filled with oil. understand those.

the oil lines on the port side are filled. there is no question about that. on the starboard side there are 3 lines. one at the top, middle top and lower one that i can not see. those lines are not filled oil, they lead into a brass fitting where the line is zip tied to. having the zip tie, there cant be THAT much pressure behind them, however i have seen oil build up on the walls of these oil lines. and it appears while the motor is running that what ever oil is on the walls of the lines is flowing towards the brass fittings. just need to know what they do for my own curiosity

buckda,
xd-50 is bluish.
seahorse,
sounds reasonable, however the lines on mine are not appear to be filled, maybe with more use they will become filled.
back to backda since you have ETEC 90's. can you confirm that the starboard side oil lines are filled as seahorse says they are?
-steve again

Mine are full and blue, unless I'm losing my mind. Granted I haven't popped the coweling in a while, but I'm pretty darn sure they are solid blue/green. Geez, the whole engine has like 10 parts, you think I could recall one detail.
montauk steve posted 02-13-2007 10:39 AM ET (US)
ratherwhalering,
Probably fills up once there is some time on the motor. the motor only has about 30 min. on it as of now. this weekend will be a different story!
thanks
steve

Steve, I assume (HOPE!) your dealer has run the pre-startup procedure, including a purge of the oil lines of all air. If not, stop all use NOW. You have probably used close to all the oil in the lines. If you get a "NO OIL" alarm anytime soon, there is a problem. Note that there is a crimp-clamp on the oil supply line that your dealer removes prior to start-up, and as part of the pre-start-up procedure. Take a picture of those oil lines and post it.
If you have had a dealer run the procedure, and have any doubt, try the winterization procedure, which runs excess oil through the system and which may clear any bubles in the oil lines.
Sometimes, I let the oil level get low in my tank, and get a "low oil" warning when getting tossed around. Once, after I did this, I got a "NO OIL" alarm. I shut down the engine, ran the winterization sequence, and it started right back up again. Now, if I ever get the "LOW OIL" warning, I run the winterization procedure after using the boat just to make sure no air got into the system.
montauk steve posted 02-13-2007 03:08 PM ET (US)
the dealer did the inital start up, he used the "prime oil" button on the notebook comp 2 times while i was there. it would run the process and the exhaust would smell differnt.
it will be this weekend when i can get pictures. will look to see if there are any floating around.
thanks
steve

here is a picture of a different motor:
http://s25.photobucket.com/albums/c86/erik069/1984%20Montauk%20Restoration/?action=view¤t=ThrottleCAM.jpg
in the bottom pic you can see the oil line, this particular one is brownish, (xd-100 i suppose).
also just spoke to my dealer, and like seahorse stated, they are recirc lines for the oil to the block. dealer also stated that they will never REALLY be filled like the port side oil lines. The dealer did state that there will be a slight amount on the walls of the tubes, and more after a good hard run with it.
i will get some pictures this weekend. again thanks everyone.

Steve -
XD-50 is indeed bluish, but not that color of blue. That is a more "azure", or tropical water color, versus the metallic, deep blue of XD-50.
As I said, not sure what that is in there from the factory - it may just be the color of the lines, but indeed, as others stated - once you get some hours on the motor, the color will change to brown with the recirculated oil in there.
I'm pretty confident to stand by my original answer, more or less. At least, it's an accurate enough answer for my purposes.
What I it does remind me of, however, is that little plastic oil line that broke and fried andygere's pwoerhead on his Mercury.
Those little lines are a must-check item on the annual inspection list. Inspect for brittleness and carefully look for cracks or splits at the connection...and lube them every season with silicone spray to keep them flexible.
Cheers!

will keep a look out and start to use silicon instead of wd. thanks dave.

Steve-
Did you just pick up an E-tec 90? If so, where and if you don't mind me asking, total out the door?
thx
