Hello,I got a 3.0 merc 1989 I was doing some maintence on my boat and I happened to squeeze the u shaped water hose on the engine I will leave a picture attached and I realized that some part on lower part is really hard like you can’t squeeze it like there is something in there? Is this normal or should I take it off and see if there is anything in there I tried to take them of but they where stuck on where they go if I pulled and more they might have ripped off
