A typical repair to an aluminum prop will cost $100 to $150, but expect to pay
$200 to $400
to repair a stainless steel prop. It may be more cost-effective to simply replace a damaged aluminum prop, but when a new stainless prop costs $400 to $700, the repair makes economic sense.
How much does it cost to get a prop reworked?
What is the cost?
Between $90 and $300
on average, with some repairs costing more, depending on the prop.
How much does a stainless steel prop cost?
The Cost of Stainless Steel Props
The typical SS prop repair ranges from
$140 – $250
.
How much does it cost to fix a bent prop?
From what I can see in the general market is that an
aluminum prop repair averages at about $125
. Then for a Stainless Steel Propeller, it is usually around $300. Of course, these prices will vary depending on your prop, the damage, and the shop doing the work.
Can you drive a boat with a damaged prop?
Can you drive a boat with a damaged prop?
You can, but you could make things worse
.
Can you run a boat with a chipped prop?
A dinged, bent or chipped propeller won't work as it used to and can even affect the overall engine performance
. Even if you examine yours on land and don't see any aesthetic changes, keep in mind that the damage could be internal. It can affect your pitch and throw your entire boat off-kilter.
Can a stainless steel prop be Repitched?
Propellers made from aluminum, stainless steel, nibral and bronze can be repitched
. Propeller pitch can be changed to a higher pitch (up) or a lower pitch by up to TWO degrees.
Can you change the pitch on a stainless steel prop?
You can't really re-pitch a prop since the pitch is greatly determined by the angle the blade is at the hub, which can't be altered
. If you're trying to take pitch out, all a prop shop can do is lay the blades back at the outer half to reduce bite and gain you some RPM.
How much pitch can you change on a prop?
Most props can have the pitch adjusted at a prop shop, which can save you from having to buy a new one. A general rule of thumb is that
a 1-inch pitch change will result in a 175 to 225 rpm change at WOT
.
How much difference does a stainless steel prop make?
The properties of stainless steel result in a propeller that offers
more performance and more durability than an aluminum prop
. Stainless steel has five times more stress tolerance than aluminum, which means the blades of a stainless steel prop can be much thinner than those of even a Mercalloy® aluminum prop.
Will a stainless steel prop make my boat faster?
Change Your Propeller
If you are running an aluminum prop,
changing to even a basic stainless steel prop will usually improve top speed
. Because stainless steel is stronger than aluminum, the blades on a stainless prop can be thinner, which reduces drag in the water.
What are the benefits of a stainless steel prop?
Advantages of a Stainless Steel Propeller
The blades are thinner, which reduces drag
. You have more design choices, so you can find the prop that works best with a particular type of boat. The blades won't flex at high speeds. You get better performance and better fuel economy.
How do you know if your prop is bad?
- Your boat is too slow to come on to the plane.
- The boat engine over-revs, although the boat is still moving slowly.
- If the prop is too big, the engine does not achieve maximum revs.
- The engine is using too much fuel.
Can you run a boat with a bent prop shaft?
I would NEVER run a boat with a bent prop shaft
. Prop shafts are cheap, lowers are not. “Things turn out best for those who make the best of the way things turn out” – Zachary Troy Schrah – a young man with vision far beyond his years. That is not that bad.
How do I know if my prop is bent?
Will a damaged prop cause vibration?
When it is hauled, damage to props is often easier to spot with the naked eye; look for dings, dents and gouges,
even something seemingly inconsequential can throw things out of balance and cause vibration when the prop is rotating at high speed
.
When should I replace my outboard prop?
A boat propeller needs to be replaced
if any of the blade edges or all are broken or chipped by more than 10%-15%
. However, the propeller's condition would tell how long you can use it, so unless you hit something that resulted in dents or dings on the propeller no need to replace a boat propeller.
Will a bent boat prop cause vibration?
Yes, a bend much less than that will cause a lot of vibration
. Pull the prop and get it repaired.
How do I know if my boat is propped?
A prop that is easier to turn requires less effort from the motor, so the motor is able to reach higher RPM. If a motor is running too low on RPM, then the boat is under-propped, and is over-propped
if the RPM is too high
.
How do you change pitch on a prop?
How do you add cupping to a propeller?
Cupping or adding a cup is a pretty simple geometric change of the trailing edge of the propeller blades. This is done by
bending the propellers blades' trailing edge towards the pressure face (blade surface facing aft) thus resulting in an edge with a noticeable curve
. This curved area is called “cup”.
How do you Repitch a propeller?
Will a stainless prop turn higher rpm than aluminum with the same pitch?
You may lose 100 rpm at WOT when trimmed the same as aluminum, but
the cupping on a stainless prop will allow you to trim higher, bringing the r's back the same or even a little bit more
.
What is the pitch of my prop?
Can you add pitch to a prop?
Increasing the pitch will decrease engine rpms
and decreasing the pitch will increase engine rpms. As a general rule, a two-inch increase in pitch will result in a reduction of 300 to 400 rpm. Conversely, a two-inch decrease in pitch will result in an increase of 300 to 400 rpm.
