Bushy:
However, the TCM IO-550 - as installed in new aircraft has a TBO of 2000.
Lycoming has the TBO edge in the small engine range; The O-235 has 2400 TBO while the TCM IO-240 is still 2000 TBO.
The dark horse is the relatively cheap 100hp Rotax with 1500 TBO.
I've not yet done the sums but I'd be interested in comments LYC O-235 $ per engine hour vs. ROTAX 912 $ per engine hour.
