1999 Johnson 225ho. Leaking gas/oil thru exhaust?

[Dhark1991]

Possibly lower crank seal?? When idling it seems to have a large gas sheen on top of the water and appears to be comming from the exhaust? I have around 112 to 115psi on all cylinders. Just replaced the upper crank seal months ago. The motor runs great no issues. Just at idle it seems to be leaking gas internally. There is no visible leaks around the fuel system. Is this normal?

What's the motor temp running at both idle and wot. ??

 

[Dhark1991]

Not sure I have no way of checking it. It doesn't run hot or anything?

 

[Boobie]

Is it running hot enough ??
