You can use weights to gain timing advance in a purely mechanical distributor. Higher rpm, weights move outwards, timing advances. Vacuum advance is a variation of mechanical advance intended for automobile use, where times of high manifold vacuum / low load (highway driving) can see increased fuel economy with changes in timing. Those conditions don't really exist in a boat.

You don't "need" electronic advance. But vacuum advance is not going to be the right way to get mechanical advance.

Heres a few words of experience for what your doing: thats a speedmaster distributor they sell for under 100$, IDC about the marine rated or not BUT I will say the internal module they use is a very cheap, Chinese one and if it came with its own pce coil, its garbage too. So, if you choose to run it, Id swap the module in it for a accel or dui version. Id also loctite the screws that hold rotor on . Now lets talk about the drive gear, if its the pce/speedmaster its a weird shiny bluish black and will wear fast and scallop your cam fairly quick, get rid of it and use a melonited or phosphate coated, whatever gear that matches you cam, even if cam has a iron gear.
As far as timing/timing advance, that "stock" style large cap distributor will allow about 24 degrees of advance so keep that in mind wherever you set the base, Smitty
