Well, the purists would start by asking for double hose clamps at each junction, and I tend to agree.
The hoses look reasonably new but a gentle squeeze to see if they are becoming brittle is probably worthwhile.
Not enough detail visible to be able to comment on the system's ability to handle a following see/not flood back etc. Ours has a tremendously high gooseneck at the stern (at least four feet above the waterline), so some variation on that theme would be good, but may not be practical depending on the
boat. Nigel Calder's book on
boat systems had some good diagrams I think (sorry book is on the boat and I am not).
Your system is the sort of setup that can easily flood the engine with
salt water if the engine does not start quickly. Be very wary of this. Ours has a gooseneck immediately between the engine and the
raw water injection to prevent this (and other problems.) It is a royal PITA, but I am (sometimes) glad it is there.
Check levels of all components in relation to the waterline and see if you can envisage any modes of failure that would flood the boat. It helps to have the waterline clearly marked at multiple locations inside your engine bay. It reminds you with every thing you do to the engine that there is some powerful wet stuff outside trying to get int.
