Default SIKK engines

Will probably do an engine swap sometime in the near future for my Rio. Please take a look at this and let me know what you think. [link=http://cgi.ebay.com/26cc-4-HP-CY-Sikk-Marine-Gas-Engine-Motor-RC-R-C-Boat_W0QQitemZ330219178565QQihZ014QQcategoryZ34058 QQcmdZViewItemQQ_trksidZp1742.m153.l1262]SIKK ENGINE[/link]
Not to familiar with these engines. What else may I need to do a swap? Do the engine mounts already fit? Would I need a new header? Please guys, any help would be greatly appreciated.

I won the British Championship with these engines last year, does that help?
Get them from O'Neill Brothers.com, they are the guys that import and tune them.
Standard Zen type intake and exhaust system, pref get Walbro 257 carb, Regards, Gary.

Hi Garry how do the bigger sikks compare with a zen as regards rpm? i know they have lots of torque for big props etc but would it be a good choice for say a hydro with a small prop or would the smaller one or a zen be better for that type of boat.Reason i ask is because i can get the 27 sikk for a decent price with mounts but wasnt sure it was the right motor for my new shovelnose hydro (rocket) spinning a 6717/3 prop any help appreciated,sorry to hyjack the thread but it may give you some extra info .

marno1fan,

lots of people use sikk over zenoah for that thunderboat class. to run that class you to use a stock motor, so the higher hp & RPM's from the sikk motor come in handy at that point

Hi mate yea i know the sikk has a few more rpm than a zen but the bigger 27 cc sikk seems to be used on larger boats thats why i was wondering if its suited or if id be better using a zen or the smaller sikk.I know the earlier smaller sikk had some quality issues but they seem to have been resolved now?,the price is good pluss you get free mounts with them too.Basically im just wondering which one of the two would be best suited to the hydro as i might go for a sikk rather than a zen for the extra power as you say.

actually it depends what district you are in. From what ive seen, pretty much all NAMBA districts will be running Zenoahs ONLY in thunderboat class. The Gas Cup in Vegas this year is also goin by Zenoah only rules in the thunderboat class.

the overall size of the motor is the same, only thing different is the inside of the motor. i am planning on putting a 27cc in my zip kit.

Yea i noticed that,seems petty to me and also for zippkits boats to not be allowed in some districts also seems petty and seems to be causing a few rows over on other forums.None of this matters to me personally as im in the uk so i just want the best bang for the pound iff possible .

Just put a Zenoah with a good pipe in it and be done with it. While the CY's do make more power... they still have more reliability issues then the zenoah.

Yea i like the zens reliability so far as ive not had any problems,just thought the extra power for similar price might be worth it.As Gary says he ran a full season with a sikk and it won the uk offshore championship and if memory serves it won with races to spare so id asume reliability has improved.Thanks for the input guys lots to do before i make a final decision anyway.

I’m very pleased to read positive post about Sikk engine, far from price, I believe it is good engine, in DDM web site they mentioned “The brand-new 2008 Chung Yang CY26 water-cooled engine is a 25.4cc (34mm bore, 28mm stroke) 18,000+ RPM performance machine. It features a red silicone spark plug cap, new blue gaskets, high-flow water jacket, 4 transfer port 34mm cylinder, high-performance single-ring piston, Walbro WT-771 carburetor (15.88mm bore, 12.7mm venturi, adjustable high and low jets), improved cylinder plating, and more! Estimated engine power output is approx 4 HP. Engine” … this power and RPM will never achieved by stock Zenoah engine.

Yea ive seen one run a few times just never seen the 27 in a hydro ,mostly ive seen them used in big boats due to the fact they will swing a big prop.

That's what I've been thinking about. I just want a reliable engine that moves the Rio around pretty well. I'm sure I want the larger G260PUM as one of the Zen websites claims 4.3hp with a pipe. I just forgot where I saw that??? Since I'm not to familiar with the Zen's, could you recommend the correct engine for me to get...what carb? So many ads I'm seeing they advertize a "big bore" carb. I just need some guidance, thats all. Thanks in advance!

I've seen a couple of those hulls run! You sure dropped more that a few pounds on that baby! One belongs to the Woodstuff's owner.
