any tips on where i should mount my graco seawater strainers for these engines? not must real estate in the engine bay. Likely going from 3 batteries to 2 as i will be running a 300ah lithium up front. Would mounting them up under rear seats be too far?(where the cutout is shown on the left side)... is there a specific hose length i should try to be under in this particular install?

thanks

Factors for SeaStrainer mounting:

Where you can see and easily service

Level is low enough for sea water to fill the SeaStrainer, but not low enough water would spill over the edge

Use a shut off valve that feeds raw water to the SeaSteainer...easily accessed and in view.

Located using minimal plumbing.

Depending on your system, the raw water pump on the engine will need to draw/siphon raw water up to prime.
