Yamaha announced on its corporate website that production is suspended this week at its outboard motors and personal watercraft plants in Japan.
Limited production is expected for next week, through April 14, the company said.
Production plans for April 15 and beyond will be announced next week, Yamaha said.
Suzuki, on its website, said its outboard motor assembly plant in Japan was scheduled to be running all week.
"As we still have difficulty in procuring necessary parts, we will operate at all plants on the day shift while we use available parts," Suzuki said. "As a result, the automobile assembly plants operate at half capacity, compared to the original production plan."
