I had same problems with my Eutikia SM 428_2003.
For rendom start look at red cable on start motor: the connection may be slack/oxidised. Anyway remove and fasten it. The contact MUST be perfect and steady.
For rendom shut down look at solenoid. Replace it or spry antoxidant inside from top. You have to remove the black rubber cover button. Than push it many times.
I hope that may help.
Buon Vento

Hi all,

A question in behalf of a friend with a SM2K from 2002 equiped with a Yanmar 100HP 4JHTE. 

Randomly, turning the key won’t run the starter motor. 
What has been established and done so far:

The battery negative connection relay, when manually reset with the button underneath it, sometimes helps the matter. 
The same relay, when manually activated while the key is turned always fixes the issue. 
The relay was therefore incriminated and changed but the random issue remained. 

All electrical connections between the cockpit panel and the starter motor were cleaned. 

There seems to be a second relay that drives the the first one. We are a bit confused by that setup.

Independently (or not?), there seems to be an issue with the shutdown process too. Sometimes the manual “kill cord” needs to be used. 

Anyone familiar with those issues? Any further tips?
