PROP GUARD will stop water erosion of the propeller and has been used on seaplane applications. However, it has very limited life on high speed propellers that are subject to a lot of water spray. Water spray will reduce the life of PROP GUARD as the constant impact of the water droplets will eventually fatigue the material causing it to become more brittle with progressively less ability to absorb energy. This constant water hammering will eventually cause it to shred, starting at the prop tip area. This is a harmless situation that causes no concern in flight, but it will require repairing the PROP GUARD installation. Some seaplane operators use PROP GUARD knowing that they will have to frequently replace PROP GUARD at the prop tip area. By sacrificing itself, the PROP GUARD has stopped considerable prop erosion. PROP GUARD will hold up relatively well on lower horsepower applications where the propeller has good water clearance.

PROP GUARD is not certified for use on certificated wooden propellers. It can sometimes be used on non-certified aircraft applications. Some varnish used on wooden propellers is not compatible with the PROP GUARD adhesive and the bond will fail. PROP GUARD has been successfully used with many varnishes. We recommend testing by placing a small sample of PROP GUARD on a surface with the same varnish before installing on a propeller.

Yes, it will bond well if care is taken to remove all traces of wax or silicone with a commercial wax and silicone remover or Naphtha using several clean paper towels.

Yes! All of the PowerUp Slick Aftermarket parts have been FAA-approved to be equivalent to or improved than Champion Slick parts. PowerUp’s Aftermarket Slick parts have been in production for 30 years and tens of thousands of our parts have been put into service.

Yes, Premier parts can be painted. They recommend using SEM Color Coat Aerosol Products. 

• SEM Technical Data Sheet and Application Instructions

However, any paint that is specifically designed for plastic should work on Premier parts, which are manufactured with a PVC-Acrylic material commonly referred to as KYDEX. Retail stores that sell automotive paint can be helpful with paint choices as most of automobile interiors are made from KYDEX also.

Yes, it can be used inside the aircraft. 

Yes, lithium battery can be installed in any position for they are a dry cell technology.

Yes, this is an anti-corrosion material that can be used on aviation as well as automotive applications. 

The oils are similar, but there are some differences. The biggest difference is in cold flow characteristics. AeroShell Oil W 100 is up to 10 times thicker at cold temperatures than AeroShell Oil W 15W-50.  However, at normal operating temperatures (around 200°F), both oils will have the same thickness or viscosity.  Another major difference is that AeroShell Oil W 15W-50 and AeroShell Oil W 100 Plus have an antiwear additive which is not in AeroShell Oil W 100. This additive, along with the semisynthetic base oils, helps reduce friction and improve flow in AeroShell Oil W 15W-50. 

These additives improve lubrication and reduce oil consumption past the oil rings. Conversely, the improved flow can increase oil loss through leaks or loose intake valve guides.  So your oil consumption may go up or down if you switch from AeroShell Oil W 100 to AeroShell Oil W 15W-50. The improved flow and reduced friction characteristics of AeroShell® Oil W 15W-50 will also help reduce oil temperatures as opposed to using AeroShell Oil W 100. 

This is particularly important in engines that run hot, like turbocharged, high performance or aerobatic aircraft engines. Pilots should always remember to monitor oil temps to ensure that they’re not too hot. 

In cold weather, you should also make sure that the engine temperature is high enough to boil off the water that naturally accumulates in the crankcase. Temperatures in the 180° to 200°F range are recommended for most applications. Finally, if you have a marginal or slipping starter clutch, the antiwear additive in AeroShell Oil W 15W-50 may cause it to slip more than AeroShell Oil W 100.  Understanding these differences can help you select the grade of AeroShell that's right for your plane.

No, they will only include the bushing. All mounting hardware will need to be purchased seperately.

No, PROP GUARD is an FAA-PMA/STC product, but the STC specifically states that a form 337 is not required. It does require an A&P mechanic endorsement for return to service.

No. Your A&P can install the prop in less than an hour.

Yes. The fuel screen is removed by removing the standpipe. The rubber tipped plunger must be unseated before the standpipe is loosened. Failure to lift the plunger off of its standpipe seat can damage the plunger. Pull the strainer drain knob as if you were draining the fuel bowl. Block or clamp the knob in this position. Insert a smooth round tool such as a screw driver or punch in the standpipe cross-hole and un-screw the standpipe.

Yes, all Tempest aviation oil filters use a magnet. This give us an extra layer of defense to help filter out smaller micron particles that may get past the filtration media.

Yes. AeroShell straight mineral oils meet the SAE J-1966 former MIL-L-6082 specification.  AeroShell Oil W single grade and antiwear, anticorrosion AeroShell Oil W 15W-50 meet the SAE J-1899 former MIL-L-22851 specification. The AeroShell containers are labelled with both the new SAE specifications and the “former” military specifications.

No. Due to the additive technology in ashless dispersant lubricants like AeroShell W Oils, the flow characteristics of each grade are roughly equivalent to the next higher grade straight mineral oil. For example, AeroShell Oil W 100 will flow at low temperatures about the same as AeroShell 80.

Yes, the hole for the grouding strap is drilled and tapped, ready for strap installation as necessary.
