Yahama motors?

Question:
I have a 1987 yamaha 115 outboard that smokes really bad, I had the oil sending unit replaced a year ago and now when it starts to smoke you can remove the cowling and there is oil inside the cowl.The motor runs strong and I would like to keep it Can anyone help

Answers:

Is there still a concern of being hijacked by pirates at sea?

It's normal for there to be some oil in the cowling. If it's excessive it could be a bad check valve in the oil pump. Sometimes they don't seat very well and the oil can run by.

yacht master questions?

not sure what's an oil sending unit?? if someone has done the carbs., maybe they have the pump linkage wrong. the oil in the cowl means stop what you're doing and find that problem & correct it before it turns to junk. since you like the motor, i would fork over some $$ and have a pro look at it.

How can I make a car that transforms into a boat?

hi, First I would check and make sure you have no broken or loose lines,also check and make sure spark plugs are tight. seeing how you replaced the sending unit the next step is to unhook it and mix the gas and oil yourself to see if that helps.Sounds like the unit is sending too much oil. also try a can of sea foam (at any auto parts store) this conditions the motor and cuts back on smoking. If still putting oil all over then check head and gasket. good luck
