ISOLATORS FOR DUAL MOTORS

[evrgreen]

IAM USING MY YMAHA 15 AS A TROWLING MOTOR ON MY
24FT. TOLLYCRAFT. IF I HOOK IT DIRECTLY TO THE BATTERYS WOULD I NEED TO INSTALL A ISOLATOR TO PROTECT IT . OR IF I USED A SEPERATE BATTERY AND CONNESTED TO THE OTHER BATTERY .

You don't need a isolator, just connect the 15hp battery cables to battery.
