Quick Question

[jump12k]

I can't seem to find specs anywhere for my Sabre 34 I bought last Fall. I have a diver coming to clean the hull and want to replace the prop shaft zincs.
Problem is I have no idea what the diameter of the shaft is.
Anyone familiar with the 1982 Sabre 34?

A newer (1989) 34-2 on which I have sailed had a 1" shaft.

This is from the original 30 manual, I suspect the 34 is probably similar but have no proof:

The propeller shaft is solid bronze and is supported by the engine coupling and an outboard strut holding a rubber cutlass bearing. Unobstructed water flow is essential to good bearing life and to dissipate heat. Check all bearing slots for obstructions at launch time. Do not apply bottom paint to the forward or aft ends of the cutlass bearing. If worn, replacement is necessary. Propeller shafts must be perfectly straight. Bent shafts can cause vibrations, misalignment, excessive stuffing box leakage, wear of the cutlass bearing and extensive engine damage. (Refer also to Section 30:03) The shaft is 1" in diameter with a 1/4" key and standard taper except for Sabre 28's with the Atomic Four engine which has a 7/8" diameter shaft.

They've stopped building sailboats but are still in business, give them a call? 207-655-3831.

Thanks much for the info. Yeah, I knew the Sabre 30 with a 17 HP Volvo has a 1" diameter shaft. I was just curious whether my Westerbeke 27HP may have a slightly beefier shaft.
Thanks for the Sabre contact number....I give that a whirl

If it's in the water why not get behind the engine and measure it yourself?
