I previously owned a 231 with a GB engine that was intercooled, fixed waste gate. Unfortunately I had to sell the plane after I had the engine to a level where I was happy with it. I am now looking for another 231. The question is for people who have owned GB engine, not intercooled, but with Gami injectors and the Merlyn waste gate. Did this increase you time towards Major overhaul or was 1400 to 1500 still the number.
Secondly for anyone What percentage of the cost of a major overhaul can be added to the true value of the plane for resale?
