How tight should a boat propeller nut be?
Proper installation begins by installing the half nut first and tightening it just snug enough to “preload” the half nut onto the shaft against the prop hub. Tight but not with all your weight on it.
Can you over torque a prop nut?
You cant over torque the prop nut. If you cant get it to align for the cotter pin to go in use another washer behined the nut or slightly sand the back side of the castle nut.
What is boat prop torque?
Prop torque allows you to fine-tune the boat’s position while staying within the boundaries of your slip, basically maneuvering at a standstill before reaching for the lines. Using prop torque, you can make your boat cant, slide and shift without moving forward or back much.
How tight should trolling motor prop be?
It is recommended that you remove the propeller after every use to inspect for fishing line and weeds. NOTE: Only tighten the propeller nut / anode a 1/4 turn past snug [25-35 inch lbs.]. Over tightening can damage the propeller.
How tight should a nut be?
Getting them off a journey when you have a flat could leave you stranded, so they should be nipped up a bit more than finger tight. If the locking nut comes loose, the other wheel nuts should be fully tightened and Torqued.
Should there be any play in a prop shaft?
There should be no play while trying to push the prop/shaft forward or pulling it aft. If there is up and down movement or side to side movement then something is loose or the cutless bearings are worn. If the prop is moving forward or aft on the shaft then something is wrong there too.
Can you over tighten a prop on a boat?
-Advance the puller bolt clockwise (tighten) with a wrench. Do not over-tighten. The purpose of tightening is not to break the prop free, but to apply ample pressure on the end of the shaft and the forward end of the prop hub to transfer the shock, during impact, with a hammer. DO NOT USE AN IMPACT WRENCH.
Should there be any play in a boat propeller?
What do you torque a prop to?
Once the nut is hand tightened, you may now use a torque wrench to reach the specification of 55 foot-pounds of torque. If you don’t have a torque wrench, no need to worry, simply tighten down the nut with your socket. It will need to be pretty snug to avoid coming off when running your outboard.
Can I use Minn Kota trolling motor in saltwater?
The Minn Kota Riptide trolling motors have a number of “saltwater-engineered” enhancements, including stainless steel hardware, sealed electrical connections and an advanced painting process for improved corrosion protection. Never leave the motor submerged in saltwater when the boat is moored.
Is there standard torque for outboard propeller nuts?
Except for outboard and sterndrive propellers, which have manufacturer-speced torque, there isn’t a standard torque spec for propeller nuts. Here’re the directions I give in The Nature of Boats, page 260:
What do the nuts on a propeller do?
The propeller nuts purpose is to make sure the prop is seated snugly against the taper, and that the propeller can’t fall off. (Hate it when that happens.) You could always refer to standard tables of bolt torque. You’d select the recommended torque for the bolt diameter of the nut and the material used in the propeller shaft.
Why does a boat propeller deflect a block of wood?
With the boat on the hard, invariably the yard guys place a block of wood through the propeller to keep it from turning. Concentrating all that force on a small edge of a blade can easily create a slight deflection on that edge. He said it happens all the time.
What’s the best way to install a torquing nut?
“Install the small, half-height jam nut first—against the hub. Tighten it up as hard as you comfortably can by hand with a standard wrench. Then, screw on the full-size nut and tighten that down independently—again, as hard as you comfortably can, by hand with a standard-size wrench.” That’s it.
