I have a 2017 E90DPXAF with 65 hours and a serial number of 05493595. We often will run at about 3900 RPMs for 30 minutes on our lake. Never any problems. This time, I found oil that smells like gas on the transom as pictured. Traced it down to the device pictured that has a spring. 

Can anybody identify the spring device and comment on the scope of the repair?

Thanks,
Todd

If what is leaking onto your transom is gas, then your VST is leaking fuel into the intake via the vent hose (when the engine is trimmed up).  You may want to disconnect the VST vent hose and see if you can catch any fuel that may be leaking to confirm that is what is happening.  If the motor is under warranty, take it to the dealer and ask them to accomplish this.

Thank you. Guess she's going to the shop?
As I think back over the last 24 hours it could of accrued while tilted up or under way, I'm not sure. I did just go back to the boat and it's been tilted up for about  5 hours now and there's no new sign of any leakage and there was no smell of fuel in the closed up boat. The fluid had a oil type texture and color to it but it also had a smell of fuel ?
There is one thing that I did different in this last over night and that is for the first time ever I squeezed the fuel bulb a few times just cause I never have.......could that of been a cause ?

Do you have a Teleflex SeaStar (or similar) hydraulic steering system on the boat? It kind of looks like I'm seeing some linkage like you do. That fluid is a dead ringer for Seastar hydraulic fluid and trust me, I've installed and rebuilt a bunch so I'm sort of intimately familiar. You'd have premature hours for a gland failure but short of the "fuel" smell, that sure looks like steering fluid and is in the typical spot one would usually see it if a fitting or gland was seeping.

Are you running XD-100 oil?
You could have an oil leak in one of the lines that could account for the fluid on your control cable clamp.
Normally the fuel supply hoses up to the low pressure pump are under a slight vacuum, pumping the primer bulb could cause a fuel leak particularly around the low pressure pump. I suggest removing the cowling and inspect lines and pump while pumping the bulb. Also look for signs of oil under the front of the flywheel.

MORE CLUES

I went to the boat this morning and looked it over very carefully with glasses, LED light, Q-tips and found only one trace of liquid. When I removed the air silencer a path of oil became obvious, apparently originating in the area of the brass butterfly valve. (see photo) It feels like oil and I dabbed some on the paper towel to show its color. Back behind the butterfly valve there didn't appear to be any oil build up but there was just a little bit inside of the air silencer. I ran the engine in neutral and at low RPMs, max 2000, for 5 to 10 minutes. No sign of any liquid or failed connections either while down or tilted up. 

I am considering carefully placing some paper towels under the cowling and run it under load for 20 minutes or so to see if I can duplicate what first occurred. Is this a wise step before it goes to the shop? Any thoughts on dirty oil being at the air silencer? 

Thanks,
Todd

In my experience it is not uncommon to see some oil run out of the air intake after the engine has been tilted, particularly if you tilt it high and store it that way instead of it being on the trailering bracket. Accumulated oil in the lower crankcase can run out the front. Also when the engine is run at a high load condition the oiling system will go to maximum oiling and cause excess oil.

Thank you one and all !
This site has saved me money and time off the water. If not for the site I would of pulled the boat and got in line at the dealer and all for what is a normal occurrence. I've donated a little bit in the past and now I need to find something I can buy from Barnacle Bill's!
Thanks again,
Todd
