I always fog at lay up and would imagine fogging after every run would be great for start up. It makes me sick to let the boat sit for a week and then start it up. I can feel the pain the engine is going thru. That is by far the most inexpensive way to do this but I would opt for the Pre Luber system, that is the cats a$$ and the single best thing you could do for these engines. You will pay for these systems but you will also have them paid thru fewer oil changes due to no dry start, cheaper and easier oil changes because you flip a switch and the system pumps out the oil...every drop, in about a minute. They also increase capacity to help in fewer oil changes and better coverage. I plan on buying them for the next boat I get some day, the truck is run often so there is no need there.
