any help is appreciated. I'd really like to have an idea of the source before trying repair or taking to local shops.

Motor details

Sorry

Its a 2005 Yamaha 50 hp model TLR.

being you did not say it was a F or T 50 I take it that it is a 2 stroke motor, so you are left with lower unit lube or 2 stroke oil.
What does it look like and smell like?

What does heavy oil mean?

Lots of good info up front makes things a lot easier sometimes
