I appologize for all the pictures - I just want to make sure it is clear what I'm doing. I have a 01 Tige 22i Type R. I am using a 2" thru hull because I plan to expand the system from 3 bags/3 pumps to 5 bags/5 pumps. I am using a bunch of one way valves which I know is a no no but it is neccessary in order to make this a fully automatic system and there is only one per pump that will effect fill speed. The two options for locating the huge thru hull and ball valve is between the engine cover and the back seats. The placement is scaring me because of the proximity to the prop shaft and the thing that holds it under the boat. What do you think? Once again sorry if this page takes a long time to load.
