Dual protection below the waterline

The SALCA (Sacrificial Anode Line Cutter Assembly) is the first unit to combine a sacrificial anode and disc line-cutter to give you dual protection against corrosion and propeller entanglement. By combining an extremely durable stainless steel disc line cutter to our already reliable MIL-SPEC anodes we were able to eliminate the difficult installations and constant maintenance headaches associated with traditional line-cutters. With the SALCA, you get an all-in-one unit that’s easy to install, requires no maintenance, and is made with the highest quality materials.

The SALCA uses only the highest quality materials and alloys to make sure that you have a durable unit that will stay efficient through the life of the product. The SALCA is made up of 2 parts  – 1) a MIL-SPEC standard pressure die cast anode, and 2) an extremely durable disc line-cutter.

SALCA Frequently Asked Questions:

[collapsibles] [collapse title=”How does the SALCA work?”]

Simple, we’ve combined a disc line-cutter with a high-quality anode, to give boat owners better protection and less hassle. It’s not rocket science but here’s the details…

The SALCA is comprised of 2 parts: 1) A high-quality, pressure die-cast zinc or aluminum anode 2) An extremely durable Stainless Steel Disc Line-Cutter. These 2 parts combine to create a highly durable and super effective unit that’s easy to install and maintenance free, while giving you dual protection against corrosion and propeller entanglement.

[/collapse] [collapse title=”Where does the SALCA install?”]

The SALCA should fit easily on most props where you would usually put a Limited Clearance Collar Anode.

[/collapse] [collapse title=”Do I need to adjust the gap between the strut and hub to fit the SALCA?”]

The short answer is NO. We designed the SALCA to fit where most Limited Clearance Collar anodes will go. We don’t like the idea of increasing the gap between the strut and the hub, because it increases the danger of causing damage or even breaking the prop.

[/collapse] [collapse title=”Does the SALCA come in Zinc, Aluminum, and Magnesium?”]

As of the moment, the SALCA is only available in Zinc and Aluminum.

[/collapse] [collapse title=”What kind of maintenance does the SALCA require?”]

The SALCA requires very little to no maintenance at all. The SALCAs combination of an extremely durable cutting-blade and high-quality anode is meant to be a low maintenance, no hassle solution to the usual difficult and maintenance heavy issues that come with traditional line-cutters – no sharpening, no difficult installation, no constant maintenance. Just treat it like you would a regular limited clearance anode; install it properly, keep it clean, and let the SALCA do its job by giving you dual protection of an anode plus a line-cutter.

[/collapse] [collapse title=”Will the SALCA still have the same cutting power after the anode deteriorates?”]

This is a great question! At Sea Shield Marine we’ve been creating the best anodes on the market for over 40 years and it really shows with the quality of the SALCA. Like all our collar anodes the SALCA is designed with a tighter tolerance to prevent spinning, and is pressure die cast to make sure it wears evenly. No line-cutter can ever guarantee 100% protection – that’s just a fact, but we can assure you that the SALCA will perform consistently over the life of the anode. Just remember to change out the SALCA regularly – as you would with any anode.

[/collapse] [collapse title=”Can I use multiple SALCAs on the same prop?”]

Absolutely! Yes you can. Since you never know when and how entanglement will occur – you can add to your peace-of-mind by adding a second SALCA on the shaft. Example: SALCA #1 is installed right behind the Prop, while SALCA #2 is installed directly on the Prop Shaft. Now you have quadruple protection!!! Hey, when it comes to prop protection is there really a such thing as too much protection? We’ve seen this type of installation done before with great results.

WARNING! If you have a wooden boat hull be aware of “over-zincing” which could lead to passivation.

[/collapse] [collapse title=”Is the SALCA cheaper than a traditional line-cutter?”]

We don’t like the word “cheap”. We like to say the SALCA is more “cost effective”. Not only does the SALCA provide the same protection of a traditional line-cutter, but you also get the added benefits of corrosion protection from the high-quality anode – which you need to install anyway. When you add up the difficult installation and the ongoing maintenance of a traditional line-cutter – you could install multiple SALCAs and still come under the cost of most line-cutters.

[/collapse] [collapse title=”Is the SALCA easy to install?”]

Yes, it’s very easy to install. You don’t need to be a professional to put this baby on. The SALCA comes in 2 parts and uses 2 simple screws (slotted fillister or allen key) to install. If you can install an anode, you can install a SALCA.

[/collapse] [collapse title=”When should I change out the SALCA?”]

Change it out like you would any anode on your marine vessel. We can’t give out exact time periods since the longevity of your anodes is relative to the waters you frequent.

[/collapse] [collapse title=”What does SALCA mean?”]

Superior Alien Light Cutting Array!!! kidding . . . Sacrificial Anode Line Cutter Assembly. It also means dual protection against corrosion and propeller entanglement.
