I am new to boats,outboards, so heres my dilemma i bought a 79 sea-nymph that was originally set up for a merc. All of the merc controls are still on the boat. But the previous owner bought this 40 hp big twin and never tested it,or set it up.the motor has good compression and spark. I need any help i can get with this motor, i have a wiring diagram but dont know where to start, do i try and start the motor without hooking all of the wiring up? Or do i get evinrude controls and wiring? I believe i need a steering bracket but cant seem to find one anywhere. Im trying to research all i can but i am wondering where to start.
