PSS HS 1-3/4" Shaft Seal 3-1/4" Stern TubeThe PSS (Packless Sealing System) shaft seal is designed as a maintenance free alternative to the traditional packing glands and stuffing boxes. The PSS does not require a greaser drip to lubricate the shaft, if does not require packing and it doesn't need adjusting or maintaining once installed. The design of the PSS seal makes it 100% watertight when installed correctly to prevent water leaking into the bilge, and it also protects the propeller
The PSS (Packless Sealing System) shaft seal is designed as a maintenance free alternative to the traditional packing glands and stuffing boxes. The PSS does not require a greaser drip to lubricate the shaft, if does not require packing and it doesn't need adjusting or maintaining once installed. The design of the PSS seal makes it 100% watertight when installed correctly to prevent water leaking into the bilge, and it also protects the propeller shaft from wear. A mechanical seal is created between a rotating stainless steel 316 rotor and a stationary carbon/graphite stator. The stator attaches to a convoluted rubber bellow which attaches at the other side to the stern tube (shaft log) with the use of hose clamps. The rotor secures to the prop shaft to complete the installation. Because the bellows can compress and expand, fore and aft movement of the shaft caused by propeller thrust does not affect the seal created. The static carbon stator is purposely bored larger than the shaft diameter to allow for any problems caused by misalignment and vibration. Under normal operating conditions, the carbon stator and the stainless steel rotor should never need replacing, and nor should the two nitrile O-rings used to seal the rotor to the shaft. This PSS seal features a rubber bellows which is designed with durability, strength and elasticity all in mind. Seals are available in a wide range of sizes for different propeller shafts and stern tube diameters. All PSS shaft seals are certified by ABS, Bureau Veritas and RINA.Shipping Notes

Difficult to rub in; sweat and water resistant; difficult to wash off
Style: SPF 50, Size: 5 Ounce (Pack of 3)
I've used this spray sunscreen off and on for the past two years and have now decided to only use it after a long and sweaty work out at the gym when I drive home. It is much easier to apply onto the skin on sweaty/wet/moist skin than on dry skin.
It is difficult to apply and rub in on dry skin. One should carefully apply and use a finger to do so to minimize stretching the skin. The positive about this sunscreen is that it is sweat resistant and will not seep or run into your eyes. It is also water resistant; therefore, it is a good sunscreen to use if you are going swimming. However, this makes it difficult to wash off, even in the shower using a face wash or scrub.
I would not recommend this sunscreen for daily use. If you are wearing sunscreen for the purposes of avoiding incidental sun exposure, such as driving to and from places, locally, for fewer than 20-30 minutes, or if you are going for brief walks outside, use a different sunscreen that is friendlier on the skin.
I WOULD recommend this sunscreen to anyone that plans on spending prolonged periods of time out in the sun, including being exposed to direct sunlight. If you are planning a day out at the beach, or going out swimming, exercising outdoors for over 30 minutes, taking a long road trip, or planning to do any activity where you will be in direct sunlight, this is a good sunscreen to use. It will leave a white cast, however, I have confidence that it will provide the adequate protection against UVA-1, UVA-2 and UVB radiation to protect your skin.

Good sunscreen
Style: SPF 50, Size: 5 Ounce (Pack of 1)
Great alternative to chemical sunscreen, spray is a little patchy and leaves a heavy white residue but that is to be expected. Works well and prevents sunburn so it's a win.

Great mineral spray sunscreen
Style: SPF 50, Size: 5 Ounce (Pack of 1)
Purchased multiple times over the years. Great mineral spray sunscreen for sensitive skin. Does leave a white cast but that’s not a huge deal for us. Nice option for kids with sensory issues that hate goopy sunscreen.

Sun protection without the chemicals!
Style: SPF 50, Size: 5 Ounce (Pack of 3), Style: SPF 50, Size: 5 Ounce (Pack of 3)
I searched for a long time to find safe sunscreen. Prior to having kids, the ingredients in sunscreen (and many other things) were not a concern. Now, I do my best to make sure that anything going on my kids’ skin is as safe as possible. After hours and hours of searching, I finally found this product. It was more than I wanted to spend, but now that I’ve used it I won’t go back! My sons skin is as light as a sheet of paper and he doesn’t like to wear a shirt, so having great sunscreen is important. I use it for both kids as well as my husband and myself.
I do not agree with the reviews stating that this sunscreen is hard to rub in; I find it quite easy!
Just bought another pack for this summer!
