Repowering cost with rigging nema 2000 everything, latest controls, new SS props, $18,000. The boat feels like it has a 115 hp. with the torque of the twins! Easy to replace no holes added to the transom or to fill. For my boat this was an easy decision. |
It will be interesting to see the change in top speed (WOT), and in fuel consumption at usual cruising speed. Did the new motors change your cruising speed?
Sounds like $18,000 well spent! That is about what one would spend for a new Suzuki 150 on a C Dory 25.

The old BF40s would run at WOT 5500 rpms make 20kts.
Cruise at 4500 rpms burning 1.5 GPH each (3 gph combined) (17 kts)
New BF40s EFI at WOT 5500 make 22 kts. (way to fast for me)
Cruise at 3800 rpms burning 1.2 GPH each (2.4 gph combined) (17 kts)
This is where the torque matters with this set up.
Plus the plug and play aspect keeping to the original power set up in my boat. I can run in much shallower water due to smaller lower units unlike a big single motor with a deeper foot. Manoverablity is awsome with the twin motors around docks, allows more motor well space for stuff. I could keep going but don't want this to turn into a twin vs single debate. This is just information to add incase someone wants to repower.
