Hey guys I am having problems spinning hubs everytime I go fishing. I am turning 5800 rpm's with a 4 blade prop. It is spinning them when I am running full speed. I have had them rehubbed my different people and I have ran new props. Does anybody have any idea of why I am spinning these hubs?

seriously , you've spun that many hubs?? how often has it occured??

2 out of the 4 times I have taken the boat out I have spun a hub. I have to figure out something cause this is no fun.

Lack of water flow to the prop hub?

What can I do to fix this?
