Asmoil made a mistake in my opinion of discontinuing their Series 2000 Marine gear lube. I know Teague liked it a lot as did Imco.
Go with this stuff below is my call as it is what your drives need...High Pressure Lube Additives..aka ZDDP and plenty of it.
Severe Gear seems to be a cut above the green stuff.

Compare the specs:
AGM - https://www.amsoil.com/StoreFront/agm.aspx?zo=1132530
SVG - https://www.amsoil.com/StoreFront/svg.aspx?zo=1132530

A good synthetic drive lube and showers will extend the life of your drive maybe 30% I have found in working with boaters in my area who used to use the factory product.
Ove-heating and bad seals typically are what cause premature drive failures.

The multigrade oils' viscosity modifiers are long-chain molecules that lessen the change of viscosity with temperature variance. In the past, the polymer additives (used to thicken the oil) were sometimes susceptible to viscosity loss. Permanent viscosity loss occurred when high shear forces (such as the relationship between the main bearings and the crankshaft) actually break the polymer molecules into less-effective smaller pieces. On a similar note, temporary viscosity loss also occurred when the polymer molecules aligned themselves in order to create a path of least resistance.
Fortunately, today's synthetic oil and additive packages have improved oil's shear-resistance. However, oils with the same rating from different manufacturers can exhibit different viscosity ratings in an operating engine, depending on the shear stability of their viscosity-modifying additives.
This means not all synthetic oils perform alike and the same goes for conventional oil too.
