Question: Can You Heat Struts On A Boat?

What do struts do on a boat?

Struts play a very important part in the design of a vessel. They support the propellers, and also affect the way water hits the propeller, which can have a significant impact on performance and noise.

Do boat trailers have shocks?

Question: Why dont trailers have shock absorbers? Out of balance tires or rough roads cause the trailer to move/bounce/sway, but no shocks. Also, trailer suspension can be enhanced using cushioned equalizers or helper springs instead of shocks.

How are boat propeller shafts sealed?

This type of shaft seal relies upon compression of a packing material around the shaft. This material consists of braided twine impregnated with wax and tallow. The wax and tallow provide lubrication so that the twine can be compressed against the shaft without abrading the metal.

How much does it cost to fix a bent strut?

Strut Replacement Cost On average, expect to pay somewhere between $450 and $900 to replace a pair of struts. An individual strut assembly will cost about $150 to $300 so you’re looking at around $300 to $600 for parts alone. Labor alone will set you back about $150 to $300 for the pair.

How can you tell if your struts are bent?

To check for a bent strut shaft, loosen the large shaft nut at the top of each strut and rotate the shaft 360 degrees while keeping an eye on the camber reading. If the shaft is bent, the top of the wheel will wobble in and out, and the camber reading will change as the shaft turns.

How do I know what size gas struts I need?

In general the length to choose for gas struts is about 55% of the height of the door you are trying to keep open. So if you have a door that is 1000mm in height a 550mm long gas strut would be about right. In simple terms we are talking half the door height plus a bit when determining optimal gas strut length.

Should I add shocks to my trailer?

The addition of shocks also helps to reduce trailer sway, which is a result of uneven pressure applied to the trailer’s leaf-springs. One leaf-spring will compress while the other spring extends, causing the trailer to sway from side to side.

Can you make a trailer without suspension?

You DO NOT want a trailer without any kind of suspension. Years back one of my F150s broke 2 leaf springs per side from hauling a 1000 pound Toro 117 Groundsmaster for my lawn service. I added some cheap coil helper springs to the rear axle to keep it from sagging too much.

What is a cupped propeller?

Cupping. When the final trailing edge of a propeller blade has a “curl” away from the boat, it is referred to as being “Cupped.” Cupping on propellers was not always used as a standard propeller design. Because cupping can increase pitch, rpm will generally decrease.

What is the difference between stuffing box and mechanical seal?

Mechanical seals reduce power consumption when compared to gland packing. On average the majority of gland packing consumes 6 times more power than a balanced mechanical seal. Running rotating equipment with packing in the stuffing box is like driving your car with the hand brake on.

What is a packing gland on a boat?

A stuffing box—also called a stuffing gland, packing gland or packing box— forms a seal between the prop shaft and the hole in the hull through which the shaft passes while allowing the shaft to turn freely. It consists of a threaded sleeve and a hollow nut, through which the prop shaft passes.
