Hi folks, I just thought I would add my 2 cents. I too have the main top to the engine and then another step, however I think this other step is important. How do I know this? I've often had to go up and down without the front cover to the engine being on (which is where the other step is located), as I was doing maintenance and found that getting topside without that "first" step, having to get to the top of the engine in one, was very difficult. Now having said that, I've got a Yanmar 2 GM which is different than the original engine, so the step up might be higher, but for me, that second step breaks up a long reach to get into the cockpit.
