Calculate the cost to repower a boat by adding engine, installation, rigging, prop and disposal costs, then see fuel-savings payback or a new top speed.
Boat Repower Formula
The following formula is used to calculate the cost of repowering a boat.
RC = E + I + CS + PS + DC
Variables:
- 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.
