ZENOAH MARINE ENGINES AND ACCESSORIES
GAS engine tuned pipes
Zenoah Engine Spares
| Zenoah marine gas engines are the leaders in this type of model marine engine. All Zenoah marine engines have RC pumper carbs and are watercooled. Zenoah are the most popular engines in gas marine racing for several reasons: Zenoah engines are very well made and strong with high power outputs and easy to start. Zenoah make several marine engines which are listed here. |
| ZEN 2 | ZENOAH G260PUM New 25.4cc Petrol engine. Latest watercooled gas marine engine from Zenoah. Very powerful. 4 transfer ports, higher compression ratio, better port timings, single ring, bigger carb, recoil pullstart, walbro pumper carb with velocity stack, electronic ignition. |  |

| ZEN 7 | 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 13900rpm. Modified, gasflowed and retimed cylinder porting, modified gasflowed and
lightened piston, modified squish, modified induction and big bore carb. 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 here 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. ZEN7 is a copyright of Dave Marles |

| ZEN515 | NEW
NEW. BIG BORE
CARB KIT This is a REAL big bore carb. 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, fitted an external pulse line, reduced the throttle arm spring pressure to almost zero. 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 link, pulse line tube and pulse line nipple. ZEN 515 is a copyright design by Dave Marles |
