just purchased this used from some older man,,this is my first boat,im still learning obviously looking for some help,,he has no manual to give me, i've had it out twice and almost got stuck out there both times..it seems to have a issue re starting once im on the water,and stop and fish for awhile..im looking to see if anyone has info about the ignition and pressing it in when starting,im guessing im doing something wrong,,engine is a 40hp 2 stroke 1993 evenrude,he maintained it was tuned up in march,and fires great when intially launching...any tips or is there something im doing wrong? any info would be appreciated,learning on the fly by myself.thanks
