New engine io-550 F or N

[Mikey]

Hi all.
Talking about upgrading my Cessna 206 10-520 to the io-550.
Who has done it, did you do the F model or the N model?
Did you notice the performance gains etc.
Would you do it again.
Any and all info helpful.

Thanks
Mike.

Yes, the commercial operators here in Juneau have removed all the IO-550-F models. There's no comparison in reliability and performance between any other engine and the IO-550-N. They say the -N is 310 horsepower but you'll think it's a lot more.

I think the -F models should be discontinued. The cylinders wearing out or cracking on floatplanes is common place, especially amphibs.

I'm not sure what the difference is, but I upgraded this past summer on my 182 and went from an O520 to an IO550D (airplains). Engine was also ported and polished. I noticed a significant improvement in take off and climb and have no regrets whatsoevever.
