Editing Propeller (section)

===Modular propeller===
A [[modular propeller]] provides more control over the boat's performance. There is no need to change an entire propeller when there is an opportunity to only change the pitch or the damaged blades. Being able to adjust pitch will allow for boaters to have better performance while in different altitudes, water sports, or cruising.<ref name="Smrcka, 2017">{{cite web|last1=Smrcka|first1= Karel|title=A new start for marine propellers|url= http://www.engineeringnews.co.za/article/a-new-start-for-marine-propellers-2005-03-18/rep_id:4136|website=Engineering News|access-date=July 21, 2017|date=March 18, 2005}}</ref>
