Re: anodes for volvo penta 290
Single prop or DuoProp drive? Anodes are different, neither has a nose cone that is also an anode. The prop/s just slide on and held in place by a threaded nut of some kind, and no not require a puller. If you need a puller, the prop is froze to the shaft. May have to destroy the prop to remove it.
In salt water, you need to remove the prop/s yearly and grease the splines.
