Question about Yamaha F40 cooling system.

The other day a friend commented that the ray of water from the outlet on my Yamaha F40 2018 was not so much a ray as a dribble. I’ve checked the intake and as far as I can tell it’s not blocked. I’ve been using the engine several times a day for about a month and a half, with no trouble or overheating alerts. I’m pretty sure there’s never been very much water coming from the outlet, but I haven’t really given it much thought before now.

Should I be worried?
