i picked up a 78' 70 hp to replace my 84' 70 hp, both johnson. the motor presently on the boat has power tilt/ trim, new motor doesn't. how difficult is it to put the new motor on to the power set up already on my boat. i see a few extra wire connections which i assume are for the tilt/trim. these obviously need to be transferred but is there anything else i need to be aware of
