I have had my boat for seven years and for seven years I have told anyone who asked that I have a Beta 43 engine. I discovered today that I do not! I went back to the boatyard to exchange my non fitting fuel filter and got into discussion with the knowledgeable engineer. I was telling him about my various issues with obtaining the right filters. He pointed out that although my engine is a Beta and has 43 horsepower, that doesn't make it a Beta 43! It is actually a Beta 1903 which is the engine Beta built before they produced the Beta 43! So all this time I have been asking for filters for the wrong engine! Who knew! I hang my head in shame.
