Stuck Duo Prop

[LeeinFL]

Having a hard time getting my props off. I wanted to change the zinc behind the props but cant seem to get the nut loose. I soaked it for 2 days with oil and still no luck. When trying to loosen with a 1/2 drive 19mm socket and in forward gear..props want to turn..so blocked props with wood and broke socket!<br />Any advice?<br />Thanks<br />Lee

Re: Stuck Duo Prop

Recommended method is to place a piece of wood between the antiventilation plate and the props(s).<br /><br />Remember to remove any locking tabs/devices from the nut before attempting to remove it.<br /><br />Next problem may be to slide off the props from the shaft <br /><br />Add a good layer of marine grease when reassembling to make any future work on these parts a piece of cake,

hello<br /> lee<br /> block the props with a wood block.<br /> use an impact socket if it will fit. make sure your turning the bolt to the left to loosen it.<br /> that bolt is supposed to torque to 25 foot pounds. the black cone torques to 80 ft pounds.<br /> there will be one of two propnuts on the fwd prop. one has many flats and a multi-fingered tab washer that the tabs are bent over or 2 it will have a 3 tabbed nyloc style nut. the 3 tab nyloc needs a special tool to remove without damaging it.<br /> be aware that volvo douprops that are aluminium in saltwater will stick to the shaft in as little as 30 days . even when yamma lube grease is used.it is due to aluminum hubs and stainless shafts. if they stick cut them off carefully with a side grinder. takes me about 4 4 1/2 discs and an hour a prop. the inner shaft is about $360 on the counter. the outer shaft is about $1100 on the counter with no seals or bearings or labor. dont cut them or hammer them.<br /> good luck and keep posting
