During a recent visit to my very-far-from-home boat I had but a brief few minutes to spend on the A4--after 2 years sitting in dry dock. So my memory of simple things A4-related is quite foggy. It fired right up, which was both shocking and euphoric (no water flow, but I think I can handle that when I return with more parts, more time, and my Moyer bible).
Anyway:
1) Should the gear shift be able to move at all with the engine off? I'm 99% certain the answer is no, but figured I'd make sure...The A4 started and sounded great, but putting it in gear to verify the transmission,cable, and shifting mechanism were okay didn't occur to me until I was 30,000 feet up and heading home, not to return for some time to come.
2) The prop shaft needs to be removed from the boat (for rudder installation), but I couldn't do it and will have the not-necessarily-knowledgeable yard give it a try. As far as I can tell, the shaft is held in the coupling via one set screw and a bronze key (little bronze bar set in a keyway on the shaft). I figured after removing the set screw (bolt, actually), the only force keeping the shaft in the coupling might be friction from the key. One 250lb man pulling on the prop could not overcome this, at least, so I'm wondering if there's something I'm overlooking. Another mechanical fitting somewhere? Something more to the coupling?
I know coupling & shaft configuration differ on every boat, but for typical scenarios, any insight is appreciated.
