Shoreline Fogging Kit

We are in the process of buying it now. I'm learning about how this works. First Yamaha product for me.
These engines are very simple, way less complicated than an automobile engine. They are very similar to a motorcycle engine without the complicated transmission.
Very easy to work on and maintain.
I have owned all sorts of different boat types and the Yamaha jet boats are by far the easiest to own.
 
I found an old tech exchange notice. Granted this is from sometime in 2012 so it really isn't "directly" for the current models. They DO recommend fogging before storage, as well as "Regularly" during the season, and specifically call out salt environments and after rough conditions where sea spray can make it into the intake. For naturally aspirated engines they do specify spraying directly into the intake with "Yamalube Store Rite Fogging Oil". For supercharged engines they have more involved processes including directly injecting in spark plug holes. However, this is not specified for naturally aspirated engines.

I also found a "Maintenance Matters" publication from 2021 with a brief paragraph talking about fogging. They also specify roughly the same procedure using the store rite fogging oil. However They also talk about "Yamalube EFI Fogging Oil" as a fuel additive and suggest that either is fine. The fuel additive seems more appropriate for an outboard engine with a small fuel tank than it does for a jet boat.
I think on the can of fogging oil spray it mentions the two second application into the spark plug holes.
 
I believe these engines use a speed density system instead of a mass air flow system. My Mopars have been like this since I bought my first Dakota in 2002. I think MAF is more flexible but that sensor is easier to damage.

I did not do any fogging of my engine in the fall as I had figured I would be using it more this winter but it was colder than expected and the tides are very low from 11am to 3pm.
