Thank you, will call the manufacture Monday. Good suggestion, as I understand this prop is a type of "bronze" proprietary to the manufacturing.
On your other questions: Boat is a trawler style boat. Fresh water,
on the river about 1 day from the sea.
Do you mean genuine fresh water or brackish? If you're a day's
steaming from the sea, you may be in genuine fresh water.
If the water is truly sweet (ie no salt), zinc anodes are not v
effective.
Magnesium is better than zinc as a sacrificial anode in sweet water.
Your prop manufacturer will be able to advise further.
