REC 106 boat propellers

most propellers are made of

• plastic

• aluminum

• stainless steel

• magnesium

the most common propeller has how many blades

• 2

• 3

• 4

• 5

When should you use a 4 blade prop

• improved top end performance

• improved acceleration

• less ventilation

• less cavitation

the theoretical distance a prop travels in one revolution is known as

• diameter

• pitch

• thread

• slip

what is the reason for asking a customer how they intend to use their boat

• so you can properly install add ons

• so you can properly prop the boat

all boats can have both fast acceleration and top speed

• true

• false

the type of propeller depends on what hull type you have

• true

• false

________ pitch has better acceleration and lower top speed

• higher

• lower

• mid

• no

______ pitch has lower acceleration but higher top speed

• lower

• higher

• shifting

• no

______ is known as the amount of wasted energy or percentage of inefficiency

• cavitation

• ventilation

• slip

• bite
