ZENOAH 7
G260PUM RACE
25.4cc Petrol
engine. Full mod marine engine with recoil pull start and electronic
ignition. Race modified 2009 higher torque version 7.3 bhp at
15,100 rpm and still producing 5.36 bhp at 19,500 rpm peak torque of 2.64
ft lb at 13,900rpm. Modified gasflowed and retimed cylinder porting, modified gasflowed and
lightened piston, modified squish, increased compression ratio, modified induction
port, and timing and big bore carb. Piston is relieved to prevent
seizures. This is the most powerful modified
Zenoah that you can buy. On water rpm of 19,000 to 19500 rpm. We test our
engines on 2 dyno's. A Zen7
running in a prototype of our new SIGMA 51" mono ran 60 mph on its
first test. Link
to ZEN7 running at 60 mph in a SIGMA mono
We develop our engines using 2 dynos. Check out one of our dynos

A ZEN7
engine won the biggest 2005 Gas boat FSRV race in Europe. In the 2005
Hannover International our Thunder boat with ZEN7 using the ZEN 21
header and CS23
tuned pipe beat all of the specialist 25cc and 35cc racing boats. This
boat and engine qualified in 1st place, 4 laps in front of the others and
won the Final by 3 laps. It needed real power, good throttling and
reliability to to do that. The ZEN7 has all of those things.
In 2006 at the Haarlem International in Holland, our ZEN 7
powered boat passed all of the Quickdraw and CMB 35cc powered boats and
had the fastest laptime (measured by the AMB computer system) in its
heats.New main page

BIG BORE
CARB KIT AND ALUMINIUM 90 degree INSULATOR BLOCK
This is a REAL big bore carb with
linkage and insulator block that rotates the carb 90 degrees. This removes
any vibration problems from the carb and so the ramp on the plastic
bellcrank does not wear.. 15mm
bore carb which has no butterfly and so has far better
flow figures than a normal Walbro carb. This carb has been bored to 15mm
and has an aluminium barrel for strength. We have modified the popoff
valve pressure. The
improved throttling/torque and increase in peak power with this carb
on a modified or stock engine is immediately apparent. The kit comprises modified big
bore carb, throttle bellcrank type link, insulator block and gasket
and is a direct replacement for the original insulator block and butterfly
type carb (644 or 257)
THIS IS NOT A WYK33 CARB and the aluminium barrel and linkage will not fit
a WYK33. This carb has a bigger bore than the WYK33.
