I¡¯m looking at doing the same conversion. I have the 120s with a couple tired VP D2-40s. My concern was the increased immediate load vs the ramped up torque via the ICE. Would love to get it installed by end of year!
Seems that saildrive conversions is a recurrent issue here.
Have any of you ever made a conversion to electric on a saildrive ?
I would like a direct driven solution too.
But I need an electro motor optimized for 1600-2200 RPM. Not 5000.
Do any of you know a supplier who can deliver such low rev (optimized) motors ?
Do we have to go to China for this, or are there still qualified suppliers in the West ?
For power rating, my Volvo Penta 100S saildrive is supposed to be supporting a 24 HP diesel.
But the torque, and the torque forces when changing direction (eg. from full forward to full backward) might not be a good cup of tea for the small gear wheels of the lower part, as electric powered motors has so much more torque power.
Please comment :-)
Hi Flip
I have a similar issue one of my 2002 engines is 35 years old and not got a bright future, rather than a rebuild, an electric motor fitted to the S120C saildrive is my preferred option.? Have you considered using the rear gearbox mount only or building a frame to utilize the 2 diesel mounts as well to handle the lateral force from the rotating prop?
I will be watching your progress with interest. Motor direct coupled to vertical shaft is intriguing
