A rational notion indeed.
It appears the sponge is getting a negative perspective because it dried to dust, and was sucked into the engine. On the contrary; there are those who have replaced the sponge as part of their maintenance
schedule and have avoided such failures.
It's good to read the posts herein to help one acquire a better understanding of the topic.
Some questions to consider:
What would be the best practice for me (the reader) to protect the engine in my boat?
Does the practice warrant the expenditure of my time and/or money
Do I ( readers of post ) have the resources and desire to implement a practice?
Of course, the matter is one can do whatever one wants with their boat and money
As for my (the author of this entry) preference, I am not comfortable with thinking that elements of any kind are going to be sucked into the Yanmar
on my boat. I decided to check engine and replace filters regularly.
Thank you for post and contributions.
