A recent for sale ad for a 2 line trim pump that goes to a light weight trim kit had me wondering. Will a stock 4 hose trim pump work with the light weight trim rams?

Regarding the lightweight kit, why did Mercury only have 2 ports out of the pump just to split it at the splash well again into 4 lines?

The 2 port pump that came with the lightweight kit looks similar to a old MerCruiser pump.

Ive got several 4 hose pumps. Some even say high pressure use only on 1400/1500 motors. Some single solenoid, some dual .

Thanks in advance
