What would be the approximate difference in weight for a Continental 100 hp engine compared to a 150 hp?
Which variants are you specifically talking about?
The Continental O-200-A (100hp) weighs 170.18 lb (77.19 kg) dry, without accessories.
I can't find a 150hp Continental, so here is the closest variant I could find:
- Continental O-300 (145hp) weighs 268 lbs (121.5 kg) dry, without starter or generator
- The O-300 is also listed as a C-145 and as a C-175
- E165-2 165 hp dry weight 351 lb (159 kg) - Variant of the O-470
- E165-3 165 hp dry weight 352 lb (160 kg) - Varian of the O-470
I hope that's what you were looking for.
