But fuel consumption spec is 129 L/H and I get 128 L/H so it is clear engine is not overloaded.
I think both engine can take more load up to 129 L/H fuel consumptions.
I also upload a video and pic.

Those engines are rated at 2300rpm full load therefore during sea trial if the engine is correctly loaded you should see up to 2350 RPM. If this is a new build I would be looking at the propellers as you need to increase the engine RPM by at least 150rpm. If these engines are left in an overloaded condition then running them at constant full loading can reduce the service and overhaul intervals.

during sea trial i noticed a lot of engine can not reach at top RPM. today i performed one sea trial 9HP00838/836 C-12 engines.
desired engine speed 2410 RPM
Engine speed 2150 RPM
fuel consumption 128 L/H
i record these parameters on ET so what
was engines overloading.

I just saw your other post with regard to the engine not reaching 2350 RPM. What you need to be looking for on ET or an MPD panel if it is fitted is the engine load factor and if possible (ET) desire RPM. If your load is at 100% and the desired RPM/ throttle position is full then you have a loading issue which could be down to a number of issues i.e.. Propeller, weight, dirty hull, incorrect trim etc.
