Re: 70 hp Force 1991
Welcome Koi.<br /><br />Cold engine Starting procedure:<br /><br />Lower engine into water.<br />Squeeze the bulb on the fuel line till its firm.<br />Insert key and turn to on position.<br />Activate "throttle only" button on the controls, advance throttle handle.<br />Push key in and hold. (this activates the choke)<br />Rotate key while still pushed in until motor starts.<br />When motor starts, release key and immediately pull the throttle handle back to idle position.<br /><br />Any problems or questions? Just ask.<br /><br />Prop is selected based on size and performance of current prop.<br />Does the boat have a tach?<br />If so, what are the rpm readings at wide open throttle? (wot)<br />What numbers appear on the current prop? You may have to remove the prop to see the numbers on the end.<br /><br />My guess, without more information, would be 10.5 diameter X 13 pitch.
