Yamaha Motor Co Ltd today reported sales of ¥1047.9bn for the nine-month period ended September 30, 2013, a 15.2 per cent increase compared to the same period year ago. Its net income increased 84.2 per cent to ¥26.3bn.

The company credited improved results on higher sales in its motorcycle, marine and power products categories.

Its marine business, which includes outboard motors, personal watercraft and sport boats, reported sales of ¥185.2bn, up 20.3 per cent compared to the same period a year ago. Its operating income was ¥24.5bn, up 129.2 per cent.

Yamaha said in a statement that sales of outboard motors increased primarily in the US because of the introduction of new models and an expansion of its “large-capacity” model line, along with depreciation of the yen against the US dollar.

In August, Yamaha said it expects companywide sales of ¥1,450.0bn for 2013, up 20.1 per cent over the previous year. It expects net income to reach ¥34.0bn, a 354.0 per cent gain over fiscal 2012. It did not revise forecasts upon releasing its nine-month results today.
