I like to add a manual water
pump to my sailboat as an extra safety
I never Had one or saw one, and I need your advice if you have any experience with water
I like to know what brand and model is good?
What metal should I choose for the pump?
How many gallons of water per minute a pump should be able to manage to be considered good?
Where I can buy it from, and how much it costs roughly?
Thank you so much.
