AMSOIL Marine Dual Remote Filtration System
Marine Dual Remote Filtration System
The BMK18 is packaged in kit form, which includes the Dual filter mount, mounting hardware, hoses, hose fittings,
component parts and installation instructions. In addition, adapter kits of four different sizes enable the BMK18
to be installed on a wide variety of recreational and light commercial marine engines.
- BMK-18 Frequently asked Questions
The BMK-18 is designed to be installed in harsh marine environments. The hose fittings are coated with a 3 ml layer of Alumiplate™ and 1 ml of zinc and yellow chromate. Standard hydraulic fittings typically survive for 96 hours in the grueling ASTM B-117 Salt Spray Test. When we subjected the Alumiplate™ coated AMSOIL Marine Bypass System fittings to this critical corrosion resistance test protocol, they lasted over 1,000 hours! This means the Alumiplate™ coating on the fittings of the AMSOIL Marine By-Pass Filtration System is 10 times more corrosion resistant than standard zinc and yellow chromate plated fittings! While this exclusive Alumiplate™ coating process is expensive,
The Marine Dual Remote Filtration System (BMK18) offers easily accessible remote mounting capability for a
full-flow spin-on oil filter and a spin-on by-pass oil filter. This unique combination of both full-flow and
by-pass filtration on a single mounting manifold is the only system of this kind designed specifically for marine
The effects of marine engines
running predominantly at or near full throttle after extended periods of non-activity include high operating
temperatures and increased potential for wear on engine components. Dual remote filtration is a highly
efficient filtering process capable of removing the vast majority of particles in the 5-20 micron range; those
that cause the most wear. Dual remote filtration also has the ability to effectively remove particles down to
one micron in size. The AMSOIL Marine Dual Remote Filtration System (BMK18) offers a clear advantage by
providing better oil filtration, increased oil capacity and longer oil and filter life.
The BMK18 requires a one- to
two-quart oil volume increase, offering increased oil cooling capabilities. The additional hoses, fittings, filters
and aluminum mount assemblies also allow the engine oil to dissipate heat more efficiently as it passes through the
filtration system, extending the service life of both the engine and the engine oil.
Marine Dual Remote Filtration System is designed to be used in harsh marine environments. The hose fittings are
coated with a 3 ml layer of Alumiplate™ and 1 ml of zinc and yellow chromate. This Alumiplate coating is 10 times
more corrosion resistant than standard zinc and yellow chromate plated fittings. While standard hydraulic fittings
typically survive 96 hours in the grueling ASTM B-117 Salt Spray Test, the Alumiplate-coated AMSOIL Marine By-Pass
System fittings lasted over 1,000 hours. In addition, the fasteners and mounting bracket are stainless steel and
the hoses are U.S. Coast Guard approved.
Fewer Oil Changes
Depending on the
boat owner’s hours of use, the improved filtration of the Marine Dual Remote System, along with the use of AMSOIL
synthetic lubricants, could completely eliminate oil and filter changes during a typical boating season. With
marine engines located in a relatively confined and remote space within the watercraft, ease of filter access and
reduced oil spillage are also significant benefits of the BMK18.
A large number of marine diesel engines have
by-pass oil filtration systems installed by the engine manufacturer. Until now, however, this technology has not
been available to smaller pleasure boats and light commercial marine applications. The AMSOIL Marine Dual Remote
Filtration System was specifically designed for recreational and commercial marine applications that use inboard or
inboard/outboard stern drive engines.
The BMK18 is packaged in kit form, which includes the Dual filter mount, mounting hardware,
hoses, hose fittings, component parts and installation instructions. In addition, adapter kits of four different
sizes enable the BMK18 to be installed on a wide variety of recreational and light commercial marine
gasoline-fueled engines, including those manufactured by Chris Craft, Chrysler, Crusader, Evinrude, Johnson, Gray
Marine, Mercruiser, OMC, Pleasurecraft, Universal, Volvo Penta and Westerbeke.
The BMK18 kit offers a new heavy-duty, machined aluminum adapter and retaining nut that fits on
the existing oil filter mount. Each adapter kit is application specific and must be ordered separately. Consult the
Marine Dual Remote Application Guide (G2051) or www.amsoil.com for specific applications. Adapter kits are
available for the most popular filter thread sizes. When ordering the BMK18, request one of the following adapter
BK195 for 3⁄4" x 16 thread
BK196 for 13⁄16" x 16 thread
BK197 for 18 mm x 1.5 mm thread
BK198 for 20 mm x 1.5 mm thread
Also, for ease of installation in some applications, optional 90-degree fittings (BK199 and
BK200) can be mounted on the filter adapter collar. These parts are also sold separately.
The AMSOIL Marine Dual Remote Filtration System represents the cutting edge of filtration
technology, another example of the AMSOIL commitment to providing quality innovations that benefit consumers
The remote mount of the BMK18 is compatible with the AMS-Oiler™ Oil Precharger (AMK01). For added
engine protection, install the AMK01 to reduce dry starting which is typical of marine engines that sit idle for
even short periods of time.
