By "newer", I meant the one with 800 hours on it...

You r correct. Sorry my misunderstood.

And yes , that will be the better option.

In Portugal, must you observe the TBO?

Does the old engine run well?

In the UK in non-certified aircraft there are many old 912UL engines continuing to much higher hours, often well over 2000.

Yes it runs. Tight and purr like a cat without any knocks.

Well, this is also a non-certified aircraft or engine but sometimes the authorities can point as a fault during the inspection . This will be my first inspection and I hopefully that they wont look at it.

I know people with 3K+ hours on their engines. Just do the prescribed maint. in the manual, stay away from cheap aftermarket parts and don't take shorttcuts on maint. and that engine should last a long time. Just like a mototrcycle engine. Treat it well and it will run a long time.

Make mechanic's use the checklist and sign them off and keep them. This will hold them accountable for doing the proper maint. if any thing happens. It will help make them do what is necessary and required since most fail to use a checklist and fail to do a good part of an inpsection. Knowing how to do an inspection on a Continental or Lycoming is not the same as a Rotax. You're paying for the maintenance so make sure it's done properly. Also when a mechanic uses the term "IAW" "in accordance with" that legally means he did everything on that checklist or in the manual so in a court he would be held to that standard. IAW is all incompacing.

Thats a good engine and for that plane is perfect. Enought power and with an e-props, gave it some nice performance specially on takeoff.

I believe ( and hope ) that he follows the checklist for the proper maint. I like mechanics and I do all the work in my motorcycles, however in this moment, I dont have enough knowledge and experience to perform my own maintenance on the plane and on the engine. For that reason, I do prefer to give this job to the him, but in a near future, I'm sure I will start to do it on my own.

What you advice on my learning path?
