Berkeley has been manufacturing pumps of many kinds since 1937. The Berkeley Jet Drive was introduced in 1960, and many thousands have been supplied to the boating public since then. Today Berkeley offers four 12J drives, each a little different but incorporating essentially the same basic features and using, where possible, many of the same parts for interchangeability.
Berkeley 12JC & 12JG Reverse Control Connector Kit
This kit is for hooking up your forward reverse cable with
all the correct parts from Berkeley Jet
This kit includes:
12JI Pump w/Hydraulic Place Diverter, Transom Assembly Not Included (With Exchange)
This pump is the latest
evolution of the family of Berkeley Jets With over a million pumps sold
we've used our knowledge to develop the All New Berkeley 12JI Pump.
This pump begins its construction with a super
tough, high strength aluminum alloy 356T alloy casting the strongest most
serviceable aerospace material around Then each unit is CNC machined,
hard anodized, and powder coated "Berkeley White™".
Each unit is assembled using only the
finest in stainless steel hardware, but its what's inside that counts.
Starting with Berkeley's unique single stage mixed flow impeller that
produces maximum thrust per horsepower. The 12JI Pump also incorporates a
special trimming device allowing you to adjust your boat's attitude while
underway through the use of a manual control. A hydraulic control is
The 12JI Pump is sold as a pump only for
replacement of inferior copy pumps or just a tired original Berkeley unit.
You can now take advantage of the factory
to consumer special allowing you to trade in your old pump for credit
towards the All New Berkeley 12JI.
Aluminum Impeller, Inducer & Shaft Kit
This do-it-yourself kit comes with a new 17-4 machined Aquamet shaft with the
aluminum impeller, inducer, shaft sleeve, thrust bearing and snap ring
If you're looking for some more low-speed maneuverability or improved
high-speed tracking then here's your answer Berkeley manufactures two models of
bolt-on rudders The first is an entry level economy plastic rudder, while the
second is a sturdy cast aluminum version of the same rudder Note: The plastic
unit will not survive in aggressive boating situations If you want durability
then you need an aluminum rudder Rudders sold complete with pin and hardware.
Berkeley Jet Stickers 4" Wide x 1-1/2" Tall
Billet Bowl Stuffer
This billet aluminum stuffer mounts into the bowl directly behind theimpeller. By closing up this clearance the hydro flow dynamics of the waterexiting the impeller is substantially increased. The result is improved holeshot and acceleration.
Note: This bowl stuffer is for use with a non-shoulder wear ring.

Berkeley "A" Master Overhaul Kit
To facilitate easier maintenance of your Berkeley
pump, Berkeley Jet Drive has created three "Repair / Parts" Kits Each kit is applicable to all Berkeley Jet Drive Models:
12JB, 12JC, 12JG, 12JE, and 12JF. There are many people attempting
to sell non-original replacement kits in an attempt to
compete price wise They short sell or remove parts to try and
compete with factory pricing Don't be mislead, get all that
you pay for, demand authentic Berkeley parts!
"A" Master Overhaul Kit includes:
12JR Race Pump Only
If only the very ultimate pump is what you're looking for then this is it
The 12JR Race Pump uses a severe duty Aquamet pump shaft, a lightened, balanced,
and blueprinted stainless steel impeller, an inducer pre-loader impeller, and a double drilled bowl with a billet
aluminum bowl stuffer. We then flow prep and clearance the assembly to race
specifications and finish it off with a proven Berkeley Droop Snoot.
DESCRIPTION: The Model 12JE
Jet-Drive is constructed of
a super-tough, high-strength, aluminum alloy, castings the
finest and most serviceable material available. Precision
machined and hard-anodized, assembled with stainless steel
fasteners, assures maximum performance with a minimum of
maintenance. Dissimilar metals are protected from each other by
inert insulators to retard corrosion. Using Berkeley's unique
single stage, mixed flow, impeller, this unit gives maximum thrust
per horsepower. Developed over a period of many years, and
field tested, assures the user of the Model 12JE Jet-Drive
many years of trouble-free boating. A popular unit with boat
manufacturers because of its ease of installation in specially
APPLICATION: Designed for
fast, simple installation in
specially molded hulls measuring 14 to 24 feet in overall length, with
a gross weight of not over 5,000 pounds per unit,
including passengers and gear.
FEATURES: No intake adapter or
transom housing required
for simple bolt in installation in specially molded hulls. Entire
unit located outside the hull, saving five inches. Lighter weight,
40 lbs. less than the 12JC. Only one rotating element, the shaft
and impeller assembly. A single stage enclosed, mixed flow,
impeller available in aluminum or stainless steel, machined to
match horsepower involved. Replaceable, insulated impeller wear
ring, machined to close tolerances for minimum bypass and
high pump efficiency. Strong self-cleaning finger-type intake
grate. Readily accessible and serviceable stuffing box-type shaft
seal. Heavy duty, grease lubricated, ball-type, thrust bearing
isolated and sealed for protection from accidental water damage.
Easily accessible, outside the hull, hand hole for impeller clean out
in the unlikely event of clogging. Long life, oil lubricated,
sleeve-type, tail bearing, sealed from the water. Smooth
working steering nozzle and reverse bucket for effortless steering
in forward and reverse with low, side-mounted, controls. Nozzle
0 ring seal assures minimum spray. Long blade rudder for
positive boat handling at low speeds with no appreciable loss in
performance at higher speeds.
POWER REQUIREMENTS: Approximately 10 to 27 pounds gross boat weight
requires 1 HP. Higher or lower speeds
will be obtained as gross weight varies. Weight distribution,
hull length and design are other factors affecting total
boat performance. The standard aluminum alloy impeller is
used with engines up to 400 HP; over 400 HP, a stainless
steel impeller is recommended.
OPTIONAL EQUIPMENT: Stainless steel impeller,
shift-throttle controls, instrument panels,
gauge clusters and wiring harnesses, intake fins and transom
trim tabs, hull insert or mold plug.
DIMENSIONS / WEIGHT: Net
85 pounds. Dimensions may vary and are for estimating
only. Refer to catalog installation drawings for complete
