I toss the connectors but I still run the quicksilver 6 gallon metal cans. I run a different pickup without the float gizmo.

I will attempt to describe how it all developed from the best of my old memory banks:
Early attempts to adjust trim while under power were made by home made hand pumps, equipment rams or jacks. Down trim was accomplished by bleed screws? The horizontal "side rams" was Mercury Racing's first out of the box product for racing PT. The rams attached to the transom (waterside) and "pinned" to the lower swivel bracket mount where the "Dynafloat" shock absorber would be. I don't know if these were used on BP's? This would be the standard Mercury HP trim system offered for sale until the T2 and T2X came along with a single ram thru transom design. The single ram thru transom design would remain unchanged until Mercury HP redesigned the V6 midsection transom bracket with a "stub " trim ram contained in the water side pocket of the transom bracket eliminating the need for a thru transom ram cutout, ram bracket and splash well. Some racers added 24V sources to their up button circuits for faster trim reaction but I never tried it because I did not want to spend $$$ on burned out pump motors.

Before hydraulic power trim there were sliding seats. Some were manual mechanical operated but the best ones were electric. Most of these used a DR starter motor and either a chain drive or a lead screw just like a garage door opener.
