Lasdrop Dripless Shaft Seals

December 15, 2011

Lasdrop Gen II Dripless Shaft Seal, Premium Shaft Seal

Lasdrop dripless shaft seals are the answer for an easily installed replacement to the original stuffing box on nearly any boat. Once installed, there is virtually no maintenance required. The “Original” Bellows and Generation II models will last as long as eight to ten years before servicing, while the DrySeal model will last three to five years before the inner lip seal must be changed. At the service interval, both the Original and Generation II models would most likely require refurbishing of the seal surfaces. In addition, the bellows on the Original model should also be inspected and replaced, if necessary.

Green Solution – Lasdrop shaft seals are the green solution to preventing contaminated bilge water from entering the ocean you are in. Whether you are running a research vessel in Antarctica, a fishing boat in Norway, a world cruising sailboat or a workboat in Maine, keeping the water you run in clean is a good practice. Remember, keeping water out also means keeping engine and drive train bilge water in.

Lasdrop Shaft Seals are manufactured and engineered entirely in the USA. All Lasdrop products are backed by a three year warranty. Each model is easy to install, requires little or no maintenance, and is sold as a complete kit. Installation is easy and straight forward as long as you can access the area where the seal is installed. It will be necessary to disassemble the shaft from the coupling and the shaft will need to be slid back far enough to remove the original stuffing box.

Lasdrop incorporates injection ports for water lubrication in vessel applications where speeds are over 10 knots. Lasdrop builds single injection port shaft seals from 3/4″ to 1-1/8″ and offers 2 (dual) injection ports installed for shaft sizes from 1-1/8″. Built for any budget and boat, Lasdrop supplies 3 different levels of dripless shaft seals.

Good – the Lasdrop DrySeal is a compact, economical lip seal designed for quick and easy installation. This option offers a lip seal that is in constant low friction contact with the propeller shaft, preventing water from entering your vessel. The simple, affordable solution to a leaking tired stuffing box.

Better – the Lasdrop Original “Bellows” seal is a face seal that features a vibration absorbing bellows, ideal for use on sailboats and workboats. Specially balanced for smooth rotation, this model utilizes a 316 stainless steel and carbon graphite for its sealing surfaces. These modifications and materials result in a dripless shaft seal that lasts twice as long as the Lasdrop DrySeal.

Best – the Lasdrop Gen II is a culmination of more than a quarter century of experience in shaft seal design. An exclusive feature that makes it the premier shaft seal are a unique ball-bearing drive system that allows the seal ring to “float” and remain in constant contact with the carbon graphite seal surface, resulting in a seal that’s impenetrable to water.

Navigating the Sea of Navigation Lights

Why Navigation Lights? If you plan to boat in the dark OR if you end up boating in the dark and it is unplanned OR if you are subject to local, state, federal or international regulations, you need some navigation lights. If you fall into the category of unregulated boats (kayaks, canoes, rowboats, small sailboats) you may still choose to use navigation lights to make it easier for other vessels to see you when you are out there in the dark. There are also navigation lights in LED or incandescent bulbs, that are made for unregulated boats and may be clamped, tied or suction cup mounted.

How big a Navigation Light do you need? Pleasure boats fit into the smaller boat category and typically require lights set up for either <12 metres / 39 feet or < 20 metres / 65 ft. You won’t get in trouble if you use a light that is sized for the next class up. You can get into trouble if your lights are too small, improperly mounted or not putting out as much light as they should.

What Navigation Lights do you need? This varies from vessel to vessel and even from how a vessel is used. Powerboats are pretty straight forward. Sailboats can act like powerboats OR sailboats and they may have different lights depending on their size as well as their use.

To understand the graphic below, Powercraft means the vessel is under ENGINE POWER (and this includes sailboats), while Sailing Vessels means a sailboat that is actually using its sails to move at night. There are also light combinations for anchoring and similar situations. Recognition goes to Aqua Signal for the following graphics – The information shown is based on the International Regulations Preventing Collisions at Sea 1972 (IMO).

For example – If you own a 34′ sailboat, then it must be equipped with the correct lights for sailing as well as the correct lights for powercraft. What this means in short is that you will have all your sailing lights plus a 225 degree forward facing steaming light. Visit Go2marine for all your navigation light needs.
