Enter the engine cost, installation cost, control system upgrade cost, propulsion system cost, and disposal cost to determine the repower cost.

Boat Repower Formula

The following formula is used to calculate the cost of repowering a boat.

RC = E + I + CS + PS + DC 


  • E is the engine cost
  • I is the installation cost
  • CS is the control system cost
  • PS is the propulsion system cost
  • DC is the disposal cost

What is a Boat Repower?

A boat repower is the process of replacing an old or malfunctioning engine in a boat with a new one. This can involve replacing the entire engine or just certain parts, depending on the condition of the existing engine. Repowering is often a cost-effective alternative to buying a new boat, as it can significantly improve the performance, fuel efficiency, and reliability of the boat.
