when I raise the speed to 5000 revolutions or more, one of the engines is decompensated and accelerates and decreases only, and causes the 2 engines to overheat. that could be happening ?
I’m new in this forum
Thanks

Welcome to the forum @Jems . I am not sure I am following your description but it sounds like you are cavitating. The most common item that causes this is a twig or branch lodged between the impellor and wall of the tube. It would be helpful if you could take some close up pictures of the impellors to help us help you.
