2012 Etec 60 outboard. Bought with my boat.

I need to remove the plastic housing in front of the intake ports of the outboard.
Looks like an air filter. But its not. How does one remove it ? And are there connected sensors to watch out for ?
Any help welcome. Thanks

I really do not have a clue what you are talking about or why you need to remove, but recommend you buy a service manual from Evinrude (I did and it is very useful). Recommend posting a picture next time - is this part under the top cover or elsewhere?

Photos always help here when asking for advice on how to work on something. If we see what you're looking at we can often better understand what you're talking about.

Thanks for your input.
I have no pictures. Sorry. Work on it.
The part I wish to remove is called an intake air silencer box. Black plastic. Rectangular with one as steel bolt to fasten it to the intake manifold.
If anyone has removed the part, maybe I could use some advice.
Thanks

I have Removed it on a older Evinrude (so this may not help) but it may help also It looks impossible but looking at it head on it is leaned forward to clear the bolt stud (if I remember correctly its 6 bolts and a single stud in the middle) Lean it Forward to clear the stud then slide it to your Left or the Starboard side of your boat. They have cut the seal pattern so it can be slid out to the side ONLY in that direction. Now I am talking about a Older air box so feel free to try either direction but on the older engine I just serviced it was the Starboard side.

Any luck?

Yes !!
Got some great input.
Seems simple enough. Pretty straightforward to remove the intKe air silencer. Had the Etec 60 tilted forward while on the transom. In mastup storage.
Some fresh two cycle oil drippedinto the transom well. Most likely came from the crankcase. Wanted to clean any oil that may have dripped into the interior cowling under the silencer box.
And any oil inside the silencer box.
Will now store the engine vertical.
Evinrude techs informed me that the motor can be either tilted or vertical in southern ca. Weather.
Freezing climates are a different ball game.

IIRC, over a year ago, a similar topic came up, where oil had leaked from the reservoir. My boat was in storage at the time so I couldn't investigate – but I did check after it was out.

I found that there is a rubber duck-bill valve inside the cap of the reservoir which allows air in as the oil is consumed. While it should prevent leakage outward, expansion and thermal contraction of all components (the oil itself, air inside, the plastic of the reservoir) could cause some leakage past the valve, especially if a strategic speck of dirt were involved.

I also noticed that the threads on the cap are a tight fit on the reservoir, deliberately, I presume, to stop it from coming off from vibration if accidentally left loose. So the lid could be screwed down apparently tight, but not, in actuality, tight enough to make a good seal against the gasket; which is another potential source of leakage.

These things will only result in a leak if the level in the reservoir is high (like when brand new), the motor is tilted up, and, as I think I experienced one time when my motor was new, when it is tilted to one side, and not the other. Went into the well, but not enough to go into the water, luckily. It hasn't happened to me since, but I haven't topped the reservoir excessively, either.

There will be no oil in the crankcase of an E-tec to leak out. It is a dry sump (like race car engines), so any “free” oil is scavenged, collected and reused/ recirculated back to the lubrication points (bearings, pistons, valves) in the engine. The oil and gas do not deliberately mix at any point. That would be primitive. (For an E-tec).

To clarify storage- The engine can be stored tipped up in freezing weather if it has first been tilted down to drain the water out. Unless it it stored where rain can get at it. Then it should be stored tipped down because water could otherwise potentially collect in the exhaust hub of the prop, freeze, and expand, risking damage.

While the transom in our Macs is way stronger than it needs to be for engine support, it is good form to support the weight of the engine from the ground, or to otherwise relieve the weight from the engine tilt mechanism during seasonal storage. Or during extended trailering.
