Water Reversion is a major problem with a variety of situations. For those of you that donít understand reversion, in simple terms it is when your engine actually sucks the exhaust water back into the engine due to high overlap camshafts, improper tail pipes, engine angles and more.
It used to be that we would tell people to keep the cam durations at or below 226 degrees of maximum duration at 0.50 lift on the cams to prevent reversion. However, today we run camshafts beyond 226 degrees of duration and get around it. Reversion in general
My name is Farid Halakari and I am from Dubai in the UAE. I own a twin engine Cigarette V-bottom powerboat equipped with number 6 drives and I recently switched from three-blade Cleaver-style props to four blades.

Hello Alexi, I have a 502 Mercury Mag Mpi engine in my Baja boat. I had the engine rebuilt by a shop here in Florida that installed a few upgraded parts. Since I got the boat back from the shop, it seems as though the engine does not want to run or idle well. They said they changed the camshaft and increased the engine compression ratio for enhanced performance. After taking it back to the shop four times to get it running properly, I did a bit of online research and I was told that the computer needs to be adjusted and that they could not perform that operation to my engine at the shop I chose.
What do you recommend since you do a lot of EFI adjustments and tunes?
