Re: 1982 AMF crestliner got it for free
Quickest response I can give you is on the 'float switch'...you wire it between the bilge pump and the power switch, that makes it an automatic on/off pump...there are a couple of ways to wire it in...
One way is to put it directly between the power switch and the bilge pump...this way makes it automatic only...
the other way is to wire it in with a two position switch, what this does is allows you to keep it in automatic mode most of the time, but if you need it to be on all the time, you can bypass the float switch and have the bilge pump on all the time, say in an emergency or if the float switch should fail...
If you need more info, let me know or post in the electrical section of the forum for different ways to wire it up...
As far as an acid wash on an aluminum hull, I have heard of some guys using some kind of mix with vinegar and I think water, to pre-wash their hull before spraying with zinc-chromate primer...but you might want to wait on them that know to be sure...or check on the net for "acid washing aluminum"
