Hi, I’m currently working on a project and realized all 4 trim pumps for the drives and trim tabs were locked up and corroded, So I will need to buy new ones. Can I use the same standard mercruiser pump for the drives and tabs, the tabs are eddie marine k-planes. I have heard somewhere that the pump for the tabs have lower pressure/flow than the ones for the drives, but I can’t find any information about it.
So if anyone knows anything or have tried I would appreciate any information.

Are the motors locked up or just the pumps? You can buy Rare Electrical brand on Amazon for about 150.00 ea. I've used them w/o issues.

The motors are completely locked up and I opened them up and it’s all rusty and broken. The pump it self crumbles to pieces from all the corrosion. So I will need 4 complete pumps and wondering if I could buy 4 of the same kind, or if I need 2 different for the tabs.

The current Oildyne pumps will work fine for tabs. They are actually high volume, low pressure (about 2500 psi). For tabs the connection is opposite the drives. Meaning the high pressure line (blue wire) is connected to make the tabs go down, not up.
