SEI Marine Products completed its phase two outboard project, the company announced.

SEI expanded its outboard lower-unit product range to include most 3- and 4-cylinder outboard applications.

"In a time when most marine companies are downsizing, we are proud to be expanding our product line," general manager Justin Webb said in a statement.

Oldsmar, Fla.-based SEI is a leading supplier of aftermarket sterndrives and outboard lower units.
