Gday guys just needing some help with a RCMK starter issue? i set up and bench run the motor with no problems for 8-10 tanks of fuel? i transfered the exact same run in motor in Seaducer Crackerbox and have broken 2 starters in 2 days and had the motor run in the boat (unchanged it was running sweet on the bench?) for all of about 1 minute?? if i didnt walk off i had considered torching it!! this boat has some sort of Voodoo as it has been a real nightmare from no set up info sent to Australia with boat all i got was a pic of the transom for setup?? and has been close to a year building it i was told buy a Zanoah ezy start? or a speedmaster Geezer pulley? any one know were to buy the later? as it seems to be a hot item as its sold out everywere

RCMK makes a nice engine but there starters well..suck. I have upgraded all my RCMK's with Zenoah EZ starts (best starter for any engine IMO). You can also use a standard Zenoah starter.

Hi Mate
Hi have the same problem and still I buy a new pully zenoah EZ but still lots of compression to roll the engine.
In Gizmo the say :Note it is imperative that a shortened collet be used with this four bearing engine or major damage will occur to the bearings.
I m still waiting for a help...
Regards

Don't know if you have seen the articles on Jim' RC boat dock, but RCMK starters have copped a lot of flack lately. The bottom line is that the only starter that can handle the larger capacity engines is the Zenoah Ezi-start. The latest RCMK starters have an Aluminium drive dog, which is much better than their plastic effort, but then the ropes break. The US distributor now sells RCMK engines without starters, and you can buy whichever starter you like. Zenoah have just released a 29cc engine, and it has an Ezi-starter as standard.

Thanks guys have got one on the way. im building a 46" Crackerbox that i have spent a lot of time on cut a long story short ive lost all the setup info for the boat? and have had trouble finding any thing in regards to setup for a 46" its a Seaducer Hull and i dont think? there are many of them in Australia? (i could be wrong?) there is a pic of it in the pics here (labour of love) but just wish i knew how to post them here
