Propped and trimmed right, that Javelin should have a lot more low end torque than the 2000 25 HP for getting it up on plane. Most of the 30 javelins were short shaft – be sure your motor length matches your boat transom. The electric start is a 6 volt system, but will work fine on 12 volts as long as you don’t have the optional 6 volt generator and hold the electric choke on too long.
