I have a 75 hp merc that i put a stainless steel quick silver lazer 2 prop on about 13 years ago. The last couple of times out i noticed it pulling high RPMS while going real slow under 10 mph. Talked to a few people and they think that my hub has spun inside the prop housing. Mine is pressed in And only one place in my area can un press them and re press them. (not something i want to tackle on my RCBS press) Anyway put my Alum. prop on and as soon as it stops thundering i'll take it out and see if it has stopped revving. Just wondering if anyone has run into this problem, and what is the best course of action is, IE replace the hub or replace the prop? I haven't got a firm quote on replacing the hub, but i am hearing $150.00. I can't remember what i paid for the prop. It was a ebay buy.
