600hrs is a lot of life still!
I'm going to try my utmost to buy a new engine, or at least at this stage my thinking is along this route.
Regrettably I've had a catastrophic engine failure in my Mooney when the crank shaft broke and in the forced lob the plane was written off. No one was injured, 4 on board, but if I never again have to go through such an event, it will be too soon
Saying that, I know there are no guarantees with mechanical objects, but I'll have great peace of mind in knowing I have a new donkey up front. Finances dictates, so when the time comes and this is not possible, I'll naturally opt for alternatives
I'm thinking of the XP IO-360 (180hp), which is mogas certified too. If I have the money, I'll go CS, alternatively FP.
