The air intake on my engine is sort of "pear or Hearsy Kiss" shaped. If you look at the 5444 schematic at the Torrenson Marine site- it is cylindrical in shape with an element inside of it. I took mine apart to discover no elemnt inside, when I called Torrenson, they knew nothing of the "pear or Hearsy Kiss" shaped unit only what's on their website. Who has a unit like mine ( I have always seen this unit in O'Day 39 for sale, engine photos). Is the inside of your unit empty or do you have a replacable element and if you do where do you purchase it?Thanks in advance...
