On the trailer everything works ok. At sea my1997 174CC cobia is moved by my C80TLRV yammie until it runs at3,500 rpms or more for more than 3 to 5 mins. Then the alarm goes off and it goes to 1,500 rpms. I check the water inlets, ok, the cooling water coming out is ok and is not even warm. Alarm stops just by running at idle. Then if you try to rev up, it starts making weird noises and vibrating a lot. It all goes to normal if I rev down to 1,500 - 2,000 rpms. What should I check or have replaced. I want my yammie working as it should. Any help very welcomed, THANKS in advance.
