Thruster Replacement Propeller - 250TT Left Hand

Lewmar Thruster Replacement Propeller — Left Hand, 250TT (589552)

A left-hand replacement propeller for Lewmar's 250TT bow thruster — these units run twin counter-rotating propellers rather than the single 5-blade prop used on smaller TT models.

Why It's Worth It
At the 250TT's higher power and tunnel size, a single propeller can't deliver the same smooth, quiet, efficient thrust the smaller range gets from one 5-blade prop — so Lewmar pairs two counter-rotating propellers instead. This is the left-hand half of that pair; ordering the correct hand matters, since installing the wrong one will disrupt the counter-rotation the design depends on.

Fitment Note
There is some inconsistency across sources on which part number is LH versus RH for this thruster line. The majority of current retailer listings confirm 589552 as left-hand (paired with 589551 as right-hand) — if you're matching against an older parts diagram that shows different pairings, double-check against your specific thruster's serial number or contact Lewmar directly before ordering.

Use
A direct replacement propeller for the 250TT thruster. Available to match Lewmar thrusters from 140TT to 300TT generally, though propeller pairing is specific to each model. Always confirm which side needs replacement before ordering — these are not interchangeable with their counter-rotating partner.
