When you say "trim pump", I’m assuming you mean just the trim motor, correct?
First, was this trim unit used in salt water? If so, you will probably need some help from the torch to loosen the three screws securing the trim motor, which means removing the engine.
The newer engine stern brackets/trim units could supposedly be removed from the engine without taking the engine off the boat, but you would probably have to loosen the engine mounting bolts at least to loosen the stern brackets "grip" on the trim unit.
There are three phillips screws securing the trim motor, one of which is definitely not accessible from behind. I guess if it was me, I would try to loosen the screws before removing the engine to see if they will come loose. Remove the engine only if you have to. You won’t need to remove the steering cable, just back the engine away from the boat a bit so you can get at the hidden screws….Be sure to get a new oring for the tilt motor and grease up the screws before securing the new tilt motor. You can use dexronII tranny fluid to refill the unit when some spills out during tilt motor replacement. Just remember that the unit should be filled when it is in the UP position, be sure to engage that trailer lock before messing around under there….
