hi guys im trying to find out what pumps are needed to replace exsisting pumps in a 2004 zx250. its for a friend of myne that doesnt know what he has and i live 100 miles away. Im looking for a list of bilge pumps and areators, including recirc pumps he needs to purchase. I know in the i class there was space issues with what kind of pumps you need to buy. Is that an issue on the zx boats? And if so can i replace them with mayfair or johnson due to space issues?
