Block
Porting
Every block is cut to meet
the customer's needs. For example, I wouldn't "Hog" out a 260hp
motor on a heavy lake type boat and kill all the torque. And you
wouldn't just skim a light race boat back half and leave potential
untapped power. At JSRE, we know what works. We do not experiment
on your motor!
Port 260hp Motor to Drag Specs ........$500.00
Port 300hp Drag Motor ......................$400.00

Reed Plate(s) Cutting
Have you ever looked at the way
your 2.5 feeds with air through the intake plenum? It feeds in a straight
line. Cylinders number 6, 5 and 1, 2 are always robbed of air. Let
the pros at JSRE angle cut your intake plate(s) to help this problem and
pick up 200 to 300 rpms.
Angle Cut Intake Plates........$ 55.00
Cut Intake Plenum..................$95.00
Cut Both Plenum and Plates........$150.00 |

Reed Cages Sealing Rings Honing
Let JSRE lap your reed cages on our
Lap Master to make reeds seal better and extend their lifespan.
Stop letting your bottom-end horsepower leak back into your intake area.
JSRE also laps your sealing rings to eliminate crank drag.
Lap Reed Cages (set of 6)...........$60.00
Lap Sealing Rings (set of 6)........$60.00 |
"Dry Stacking" Exhaust
JSRE reroutes the water from your
2.5. Your motor will get rid of spent water through 4 hoses instead of
2. We reroute water away from passing across the tuner area, and send
it to the water pump area via tubing. This has made a difference in the
motor's ability to draft or scavenge.
Dry Stack Tuner Adapter........$150.00 |
Tuner Modifications
Every tuner modification will be
different according to the application. (Modification of motor, weight of
boat, etc.)
Modify Core Tuner........$100.00 |
Down Housing (SS New Style)
To keep your exhaust from making an
"L" when leaving your motor, JSRE machines a slot in the bottom of your
down housing to make expelling exhaust easier. It makes for easier
breathing, too!
Cut Slot in SS Down Housing........$65.00 |
Down Housing (Old Style)
These units need above water
exhaust relief for max launch power. JSRE drills holes above tuner in
housing and inserts 6061 aluminum tubing. We then weld it to gusset the
hole. Without the tubing your housing will break.
Cut Holes and Gusset Down Housing........$150.00 |
Lower Unit Modifications (Paddle Style)
The offshore housing on the new
style gear cases are designed for turning, not speed or E.T. Allow JSRE
to cut down and thin your skeg to an "Allison" cut like the one that is so
popular with the drag race crowd. We can also cut your torque tab and
install a torque tamer tab to help with steering torque. This is good for
2 to 3 MPH!
Labor for Cutting Down Skeg and Welding........$ 125.00
Torque
Tamer.............................................................$30.00 |
Lightened and Balanced Rod, Piston, Wrist Pin, and Flywheel Combo
JSRE lightens the inner rotating
assembly a whopping 100 grams X 6 (600 grams total). Along with the JSRE
lightweight flywheel, your motor will pick up 200 to 300 RPMs. Plus,
keep your high dollar motor from self destructing by breaking cranks and
premature wear.
Flywheel (Core Needed)........$400.00
Rods and Piston..................$300.00
Wrist Pins..........................$175.00
TOTAL . . . . $875.00
+ shipping |
Mercury Connecting Rods
JSRE will lighten and strengthen
your rods by cutting the cast flashing off the side beam area, thus
eliminating the tendency to crack and break under RPM stress. All rods are
digitally balanced. We check for rod stretch and straightness. Also, we
check the rod bolts to prevent bolt failure which can be disastrous to
your high dollar motor.
Lighten and Balance (set 6) Rods Small...........$150.00
Lighten and Balance (set 6) Large..............$175.00 |
Pistons
Pistons are cut on Super Indexer to
insure consistency. They are cut and balanced with digital accuracy. No
hand work! Pistons are given the JSRE angle cut at the intake ports to
enable better top-end breathing, plus all sharp edges are chamfered to
prevent cracking. A 45 degree bevel is put on the crown to prevent
detonation. Wrist Pin holes are honed to ensure perfect fit. We perform a
crack inspection and return to the customer or we will install it back on
the rod for assembly.
Total Labor With Core (set of 6)..........$150.00 |
Light Weight Wrist Pins
JSRE offers light wrist pins for
your 2.5 Mercury motor. The stock pins are 107.5 grams. JSRE pins are
74 grams and stronger than stock with a 65 Rockweld hardness
(Indestructible!) What better way to reduce reciprocating weight!
Light Wrist Pins
(Without
Core)..........$225.00

Core)................$200.00
