What does zinc do? Is it needed in a high performance marine engine? That was my main concern when wondering how the Amazon 20w40 stacks up to the VR1 20w50.

Last time I was working on the boat I threaded a "T" in with a cap to prime it. I am doing an oil change soon and will let ya'll know if it helps.

Great point. One of the reasons to run a heavy oil is to benefit from the higher film strength on start-up. But 8-10 seconds on oil changes is rough. Especially when done so frequently at 25 hrs.

A pre-oiler would be great. An accumulator can be setup to dump the reservoir pressure before start-up, but you would want to change that oil on the oil change. Anti-drain back filters help too if they are in poor positions.

I like the simple solution of T to fill an upside down filter. My System 1 mesh filters are horizontal. Not to.mention the many oil hoses to the 2x bell housing coolers and external filter.
