removing a propeller

[bhs91]

I have an 2003 70HP 2 stroke yamaha and i just want to remove the prop to check to see if there is fishing line around it. If this a tough process? can anyone give me some insight into doing this?

thanks!

No.. it's not difficult. Pull the cotter pin out of the nut and back the nut off. Remove the washer(s), paying attention to the order they were on, then pull the prop off.

Reinstall in reverse order and you should be in good shape.

Might also want to put fresh prop grease on the shaft when you reinstall the prop.

what's prop grease?

[CAMAN]

It's similar to blinker fluid.

JK, its just a waterproof and heat resistant grease that you put a thin coat onto the prop shaft. It helps keep carbon from the exhaust building up on the shaft. Use a water/heat resistant marine grease or any silver colored anti-seize compound. Don't use the copper colored anti-seize, its too disimilar of a metal and may react with another metal and cause corrosion.

If you don't have anything similar lying around, just go to most autoparts stores and at the front counter they usually sell little packets of anti-seize for around a buck, a bottle of it will last you 30 lifetimes if you don't use it regularly. Just make sure it is silver colored.

Not sure o n that style motor, but on our 150hp we always would just tighten it back on to "feel". Then I actually took a torque wrench to it and torqued to spec... wow, I was surprised at how might tighter the spec is than what we used to do. Just food for thought if you have the same style hub we do (Merc), but if a pin then different. But for any of you reading and have a torqued style, use a torque wrnech some tiime if you don't at least to gget the feel. It is actually quite tight...

thanks fellas for all the input. Prop is off and back on with prop grease and free of fishing line!

bhs - not to add to something you didn't ask about, but if you found fishing line you may want to check your lower unit fluid. Fishing line can wreck the seals behind the propeller allowing water into the lower unit. Not catastrophic short-term but over time, expecially winter storage, the water in the lower unit will rust your gears and you will need a new lower unit - very expensive. Water in the lower unit will make the lube look frothy / milky. Hope this helps and Good Luck. Paul

Of course one would replace the lower unit lube in the fall before winter storage....
