RE: Range for 27MHZ and 75MHZ
Thanks Dan. I had a problem with the 75MHZ receiver and sent it to repair. I had the 27MHZ to replace it in the mean time and sealed the radio box with tapa (shiny radio box tape). I was just lazy to remove all, fix the receiver, tape it again [:D] I already have a fail safe, just in case.

Range for 27MHZ and 75MHZ
I have 2 radios with related receivers and I'm very used to the Acoms 27MHZ 2 channel radio. The other one is JR Racing 3 Channel pistol type 75MHZ. So what is the average range for both?

RE: air vents
If air was ment to leave the boat, why wouldn't the designers who add scoops to hatch do not add air exits? At the end it also makes sense to me that if you take air in, you need to let it go for 2 reasons. - If it can leave easy, it will enter more so more fresh air for the carb - I also think excess air inside will cause somehow a parachute effect. And if exits are designed nicely, maybe it can also help the aerodynamics. And still, why not already in the design of the hull makers?

RE: I hate my Zen
Changed the carb diaphram, fuel lines, cleaned the fuel tank (there were some brown particules), cleaned the fuel filter. Changed the air intake line inside the boat and made 3 circles. Removed the idle needle and used the remote control to push the gas lever slightly. High needle 1 turn, Low needle 2 turns. And I was ready to test at the garden before I go to the pond after attaching water lines the hose for cooling. After few pulls the fuel reached the carb but didn't start. Played with the needles by quarters and after 20 pulls still nothing. Took of the plug, controlled the electric wire, waited for drying for few minutes and again nothing. Then I was worried about the diaphram (or maybe I attached the gasket to the wrong side) and opened to view if all ok. O noticed that the one side where the needle was quite wet. I dried everything and also thought maybe I didn't screw tight the cap. And finally it started but stopped after few seconds. I increased the push lever idle control on the remote to max and it went above quarter. And finally it started after few more pulls. I asjusted to high needle to where I can hear the highest revs and it was above half turn. And I didn't feel differences when I adjusted low needle. What am I supposed to feel here? Less rattle at idle? And when I checked where the L was when the boat seemed to rev nicely, I was at this slightly above half for H and L was at almost 4 full turns. So are these normal? I didn't test yet on the water and my test in the garden with water cooling on was just for 5 minutes or so as I was worried of the noise that would bother the neighbours. I read somewhere about reading the plugs. Can anyone let me know the link to this useful information. And what is the ideal plug gap?

All of you have been a great great help. Thanks for the time and sincere interest on this. I'm out of town now and when I go, I will have another go if I can find a diaphram around. Having a spare walbro will also not hurt for sure. I'm convinced on the clutch advice as well because I don't want to deal with all the work besides spending extra cash for no good.

RE: I hate my Zen
This makes me clearly question then the quality of build as I don't remember boats with air vents placed like mine on top. But great advice and I'll move it inside and the the coil. I assume this would delay the water to enter the tank even water gets into the body when it flips. The air vents on the hull are very welcoming for water to enter anyway and without these it is not possible for the engine to breathe. Probably I should change the topic to "I hate my skills with Zen" [;)] Regarding clutch, why do people use clutch? I will never race my boat but it is more for fun. Clutch will also help to see if during idle if my water cooling pipes are doing the job. But is it easy to attach to the current location? And if the clutch makes the boat less fun, please let me understand why. Did anyone see those induction kits I mentioned before? Any idea if they are any good for the money? http://www.vaportrailsrc.com/servlet/the-43/Boost%2C-Boost-Induction%2C-Zenoah/Detail

RE: I hate my Zen
The pipe going up is the went. I'm also worried that water will flood in the tank if boat flips. Maybe I should extend that with longer pipe is also what I have in mind but if boat flips, pipe will be also down and still take water in, right. I have no idea why one of the pipes is blocked. It was as is since I purchased and I was able to run the boat last year for short runs like 5 mins at least with this pipe block. Are you saying to move the fuel filter on the pipe from filler to the tank? Until I took this picture, I never looked carefully to these pipes. It looks like pipe going from the filler to the tank is also the pipe sending the fuel from tank to the carb through the filler. So, putting that to filler/tank pipe means first it will block the dirt pumped to the tank but on the way back, it will take the dirt to the engine. That's why the current place looks better to me. Is there anything I'm thinking wrong? If I get the clutch, it will be with pump. One of the reasons I didn't get this boat too much on the water is it stalled many times on the water as I'm tuning it not right probably. I would also stall at launch if I'm alone. I just assume clutch should be more foregiving. Also just stopping on the water with the pump active and launch from still should be also fun.

RE: I hate my Zen
Thanks experts, I think the problem is the diaphram, photo attached. It would be quite to find carb spare where I live. Do you think I can just glue the edges? If not, please let me know an online store who sells those. And do you guys suggest that I still remove the velocity stack in my case? Removing the idle needle is a good suggestion. I have a failsafe connected to gas when radio connection is problem. I attached more photos of my boat to show the water and fuel pipes. Please let me know if any problems. I also attached the overall look of my Rico hull which I really like the design. Can I fit a clutch here? I just want a fun sport boat and launching alone, docking is a problem for me when alone. I found this internet guy which is cheaper then Bonzi but still nice CNC work and an interesting design of clutch. I also liked the radio box which locks without radio tape. I have no idea what the boost induction kit helps for. http://stores.shop.ebay.com/Vapor-Trails-RC__W0QQ_armrsZ1

RE: I hate my Zen
Thanks all for support. Need to check my carburator valve then. Regular gas is 95RON and I have about one gallon of 97RON mixed with oil. Would 2 RONs of difference cause such big problem on engine heating? BMAD01, what is velocity stack and what's wrong with it? I didn't build this boat so I'm not sure what you mean. A picture of a proper one will help.

I hate my Zen
Hi all I have a BZ1 mod Zenoah which doesn't want to start when I get near the pond!!!! Once I read here the tips on choking, I started the damn thing at home after 3rd pull with no problems. The revs were not stable but I decided to fix this with adjustments after tests on the water. It was on 95RON gas with 40:1 oil when it started OK but unstable revving. Then looking at the Bonzi website, I saw that their recommendation is 20:1 to 25:1 oil mixture so I added some more to be about 23:1 and I used 97RON fuel this time and I went to the pond to enjoy my boat's season opening. It was a very very hot day by the way. At first, it was almost impossible to pull the starter. It felt like it stuck. So I took of the plug and cylinder was wet. Probably happened while driving. There was even excessive gas coming out of carburator. I let the cylinder and plug dry for a while. And then tried again. Pulling the starter became normal but it didn't want to start. After a little choking I was able to start which was only for couple seconds. And then many unsuccessful tries. In every 10-15 pulls it would start but turn off immediatey. I played with high/low needless by quarter turns up and down and sometimes and same story. Gas stick was set at no touch, quarter level touch etc (which the idle needle should do anyway). I ended up the day with skins removed from my finger due to pulling and my back seriously hurt and no joy at all. Please let me know what the problems could be: - Is higher octane rating fuel not good? - Can the oil mix suggested by Bonzi misleading (it was just where they wrote about Amsoil 100:1 oil) http://bonzisports.com/zenoah/zenoah_oil.html - What should be my needle adjustments for H, L and idle? (I'm at the sea level) Thanks Tufan

Any comments on the below. It seems to be missed out. If O'Neill clutch does the same for me as the Bonzi, there's quite price difference and I'll go for O'Neil. Quality and looks don't matter at this point. I'm very thight at fitting the clutch so O'Neil is even better as it looks to be a shorter unit. Anything I'm missing out?

Directly or with some modifications. I will use this for easy launch and back to shore. So if it will not stay in idle more then couple minutes, is it ok to do so without water pump?
