I visit this board often and have read much about the Universal M-25 problems and related component issues. Granted, outside of the older Atomic 4, the M-25 is the most popular engine installed by Catalina, but what of the M-18 (2 cylinder) engine? It was used for a brief time before the M-25 was introduced as standard equipment. I never read of owners complaints or issues. It would benefit all of us M-18 powered folks of any problems encountered with this engine and/or its components. I for one as an owner of an M-18 with 478 hours clocked, have yet to have any issues. Am I just lucky? Bob '88 Catalina 30

I repowered with a used M-18. Runs great. Eventually you'll want to watch for mixing elbow corrosion and wiring harness corrosion that can affect starting. But those are issues that come up with age. Like my mechanic told me when I bought the engine used "she's a runner!" Enjoy. Check out the link!

By saying "issues", do you mean problems? My M18 has run trouble free for 700+ hrs now. Doug
