One more important question;
I have a discussion here with the local yard electrician who helped me with the wiring;
The H+B manual say's that I MUST connect the SS mechanism with the boat's bonding
The electrician says we may not do that, as the Hi lo mechanism has Anodes,
otherwise we would have current from the boat through the mechanism,
I don't understand his theory but he's quite convinced ...
who can give advice with the correct theory ?
thanks in advance

Due to item (ii), I would always bond it to the boat's anodes and general earth. That's the H+B recommendation too. Mine is bonded and I have no corrosion/electrolysis problems.
The "current through the mechnism" tells me he doesn't fully understand. There is nothing wrong with current through the mechanism (and we are talking micro currents of course). If there are dissimilar metals in a couple there will always be currents, but it is better to transmit them through heavy grounding wires (with no resistance losses) than through the electrical connections of the proximity switch

but agree the principle and will bond my systems as also adviced by H+B
is this a switch on the Hi lo mechanism ?
anyway, mine doesn't have that, works completely hydraulic
He works also for Canados, and they don't connect the hi lo system to ground (which I can understand and accept now)

For the hi lo platform fetishists,
Here some more pics, just to have them all together for future recovery
Also from the inside:
apologies for the dirt and untidy-ness,
utility-room floor plates have to be put in place;
remember we are reaching the end of a big rebuild project, one week left for ao sanding the teak, and cleaning.
These (removeable) steps to the transom door are in front of the hydraulic pump and valves
I'm pleased to report that the mounting is very stiff,
If one jumps on the edge of the platform, you canít see any movement of the transom on the inside. Itís a Canados remember ;-)
The mounting went really nice,
There is a small curvation in the transom surface where the system is fixed,
We measured this and gave the dimensions to H+K, they made a drawing and designed the custem C70 extensions, with a mirrord wedge of 4į
After mounting the system we had only 10mm width difference between base, and the end of the two platform arms, which I believe is very good. and was confirmed by H+K
we didn't need to move the generator exhausts, nor any other outlet.
gen cooling water and exhausts gasses might flush over the mechanism,
but will leave this for now, might change in the future if really needed.

we might want to run the engine when the platform is down, (divers recovery)
but a warning light is usefull then,
so might add such a switch to the whish list for later.
on the other hand
there is a reassuring "Klak- klak" sound, when the safety hooks lock, thought
but I'm not sure if you can hear that when the engines are running.

Lookin great now Bart. Surely a Canados 74s now?!?!
