Fitting a watermaker pumo to a yanmar 3GM

[Tomahawk]

Before we untie the fenders and mooring ropes and leave them on the jetty as per (Pete Goss) we need to fit a watermaker to our Yanmar 3GM.
Space is very limited as the boat is an Outremer 40 catamaran and access is from over the saildrive.
I can easily get a piggyback pulley for the flywheel .. I am not sure how to mount the pump?

Has anyone done this or seen it done something similar to fit an extra alternator or drive?

I believe that loads

I believe that the loads on the bearings need to be closely balanced
so adding 1 or 2 more pulleys requires that they be spread evenly around the flywheel.


The standard method may be to add new pulleys(s) for the take off perhaps the original alternator, a second small pulley for the second alternator and a suitably sized heavy duty pulley sized for the correct rpm for the Cat pump for the reverse osmosis system.

The other thing you'll need is an electromagnetic clutch (like you get on a car a/c compressor) so that you don't have to run the pump all the time the engine is running.

Does it not come with full fitting instructions?
