RT27 Classic prop shaft size

[Contento]

Searched past discussions but could not find mention of the prop shaft diameter size on the Volvo D3 R27. Am ordering a new prop nut and zinc and want to make sure of the size before hitting the order button! Am guessing 1.25" but.....Thanks.

Our R25 uses a size ‘D’ zinc. I would guess yours is similar. Usual imperial size zincs don’t fit our boat. This may be a previous owner mod, but you might check.

Thanks for the prompt reply guys. 1.250 it is. Now I can get replacement anodes ordered. After perusing this forum I've decided to go with aluminum rather than zinc. I'll be in salt water for a three or four months then trailer camping and fresh water so think the aluminum anodes will be best. We'll see.

I agree I use Aluminium in 50/50 application.

What about in fresh water?

I use aluminum in fresh water, Lake Michigan. The first year I used factory installed Zinc and all it did was oxidize and formed a coating ( did nothing) next year I went with aluminum. I feel comfortable with using aluminum in a salt water application too.
