Cutlass Bearings for a 65 mm Shaft

We list three Exalto cutlass bearings for a 65 mm (2.559") propeller shaft, in phenolic, brass and GRP. They fit an 85 mm (3.346") housing bore, and every one is 260 mm (10.236") long. The nominal wall is 10 mm thick: half the difference between housing bore and shaft.

Of these, one is in Australian stock (the phenolic MPSF65), with same-day dispatch on orders placed by 2pm AEST on a business day. You can pre-order the other two, with dispatch estimated at 3 to 4 weeks. Prices run from $410.00 (the phenolic MPSF65) to $910.00 including GST, and Express Post delivery within Australia is free.

A 2-1/2" (63.5 mm) shaft is only 1.5 mm smaller, but its bearings are a different nominal size and are not interchangeable with these. Check which unit your shaft was made to before ordering, or see the bearings for a 2-1/2" shaft.

How to choose a bearing for a 65 mm shaft

Measure the housing bore and the length of the bearing you are replacing, then find that combination below. Every bearing here shares one housing bore and length; they differ in shell material, tolerances and availability.

  • 85 mm (3.346") housing, 260 mm (10.236") long: phenolic MPSF65 (in stock, $410.00), brass MBSF65 (dispatch in 3 to 4 weeks, $910.00), GRP MGSF65 (dispatch in 3 to 4 weeks, $530.00)

Phenolic, brass and GRP describe the outer shell, and each has a grooved nitrile rubber lining. The non-metallic phenolic shell avoids galvanic corrosion between the shell and a metal housing. Exalto advises against fitting brass directly into steel or aluminium housings. Exalto identifies GRP as suitable for steel and aluminium stern tubes as well as compatible non-metallic housings. More about each: phenolic cutlass bearings, brass cutlass bearings and GRP cutlass bearings.

Matching sizes is the first check, not the last: confirm the shell material, the housing's condition and the retention method for your boat. The measuring guide explains what to record, or contact us with your measurements.
