Replacement Engine for M20S

[mooneyflyer]

I started looking into a new engine for my Eagle. I have an IO550G. My POH says IO550G. But my TCDS indicates IO550G6. But according to Air Power, Continental no longer makes the G6. What are my options?

Nothing wrong with a new engine, but I might consider just getting a good shop to overhaul what you have.  A good shop should be able to do that and end up with an engine as good as a new one (or better).  It will probably take less time too.  If you want an engine on hand, I might call western skyways and the other big shops to discuss.  They might have a core (or know how to get one) they could oh to new limits and take yours on exchange.

I would speak to Bill Cunningham, PowerMasterEngines   www.powermasterengines.com

He overhauled my I0-550G.  Excellent product and currently in service after 10 years.

If you have the 310bhp STC, you’re authorized to purchase the IO550N(_)B…either Factory Reman or Factory New.  You’d replace the (_) with either an “8” if you don’t have air conditioning, or “39” (I believe) if you have ac.  This is usually the best and most cost-efficient time to make this change…given the “N” engine variant is the same cost as the “G”.
