Hi y'all
I recently acquired a 1996 johnson ocean runner 115hp with 140 hours on it.

This is my first time dealing having a 2 stokes and i have a few questions/concerns about the motor that i have noticed after spending a few hours running the engine.

First, at ideal speed you see a slight oil slick behind the boat. I can't pin where the oil or unburnt oil is coming from. I have read a few other forms with fellow owners saying this is completely normal and these engine are thirsty for oil.

Second oil/exhaust, I ran the boat for 3-4 hours the other day it started right up, no smoke and absolutely no issues running but at the end of the day i was hooking up the hose to the engine near the exhaust port up top to flush it out and I noticed there as a glob of gray unburned fuel/oil mixture in the exhaust port.This cant be normal right?

Third, I trailer the boat and i have noticed that when the boat sits for a few days down the engine shaft from the top there is a small leak and coats the shift with a blue tint. i haven't searched enough to find where it is coming fromyet. anyone have any pointers where to start.

I know people say seeing oil can be good thing for 2 strokes but i am concerned i am burning to much oil and would like to prevent any future issues.
Any input on the following subjects would be great, thank you all for your help!

No i have been using ethnol free gas.

Am i wrong by saying if the engine was being over oiled wouldn't the exhaust be smoky? (which it has been smoky)

thank you for your insight.

Smoke on a 2 stroke is normal.-------Some oils smoke more than others.------Some gas and oil goes right through the motor without doing anything ( wasted ) and shows up in the exhaust.-----And lubrication in a 2 stroke engine is not well understood and the subject of much discussion.
