In respect to this, when should I replace my boat prop?
8 Clear Signs It's Time to Replace Your Boat Propeller
- It Has Too Much Pitch. When researching propeller sizes, you'll notice two numbers associated with each one.
- It Doesn't Have Enough Pitch.
- It's a Compromise Propeller.
- You Damaged It in the Water.
- It's Made of Aluminum.
- You Want to Go Faster.
- You're Losing Gas.
- It's Not the Right Diameter.
Also, how do you know if your prop is slipping? To tell if your hub has spun, mark a line on the back of the prop hub with lipstick. You can also score your mark using a file. With the mark in place over the inner and outer hub, it's a simple matter to pull the prop and see if the mark has broken in two. If it has, you have spun a hub.
Similarly, it is asked, how tight should a boat prop be?
When you go to tighten the boat prop nut, you want to make it tight, but not crazy tight. A general rule of thumb is to tighten it by hand and add a 1/4 turn extra. You can find exactly how much torque to use by looking in your service manual for the engine you are tightening the prop nut on.
What size is a prop wrench?
1 1/16" or 1 1/8", can't remember off hand as my rapid jack plate takes one and the prop takes the other. Take 'em both and you are covered. 1 1/16". You'll need a deep socket.
