Installation Basics

Read the directions!

Avoid tight hose bends and excessive runs.

Use heavy gauge wire.

Boost Pump must be installed below waterline.

Install Spectra-Pearson Pump as low and as close to the boost
pump as possible.

Use a dedicated thru-hull with scoop type strainer.
Thru-hulls
It is mandatory that a minimum 1” diameter, dedicated, forward facing, scoop-type intake
thru-hull and seacock be installed. Install the intake for the system as close to the middle
and as far below the water line as possible. Thru-hulls in the bow area are susceptible to air
intake in rough conditions. Sharing a thru-hull with another system is not acceptable and
will void the warranty. Sharing a thru-hull can introduce unforeseen problems such as
intermittent flow restriction, air bubbles, and contaminates. For racing boats and high speed
power boats above 15 knots, a retractable snorkel-type thru-hull fitting is preferred to be able
to pick up water away from the hull.
Do not install the intake close to or downstream of a head discharge. Install as far below the
waterline and as close to center line as possible to avoid contamination and air induction.
The brine discharge through-hull should be mounted above the waterline, in or just above the
boot stripe to minimize water lift.
Double clamp all hose connections below the waterline.
Pipe Fitting Instruction
Plastic to plastic fittings should have 3 to 4 wraps of Teflon tape and will thread almost all
the way in.
Avoid getting dirt or debris into the piping or hoses during assembly. A small bit of
debris can stop the system! Avoid getting tape over the end of fittings that might get into the
system. To ensure this does not happen, leave the very first thread uncoated.
Avoid restrictions or long runs on the entire inlet side of the plumbing from the thru hull to
the main feed pump module.
Prevent tight bends and excessive elbows. Any restrictions will hamper system performance.
Secure the piping away from moving objects such as engine belts and hatches. Prevent chafe
on the tubing as required. Test and inspect all piping and hose clamps after several hours of
operation.
