Tests of Outboard Motors Starting in Gear.
Abstract
Tests were conducted to determine what level of acceleration caused loss of balance for a standing person in order to consider whether outboard motors should be fitted with thrust-limiting features. Initial tests were conducted with test subjects standing in a truck. In the most stable position, on centerline facing to the side, 52% of the subjects lost their balance at 0.3 G's or less. In the least stable position, facing aft, 87% lost balance at 0.27 G's or less. In boat tests wherein a single passenger stood in various boats equipped with motors ranging from 6 to 40 HP, the smallest motor (6 HP) did not produce significant unbalancing acceleration with the lightest boats, whereas the next size (9-1/2 HP) motor did.
