Welcome aboard Coastalchix and congratulations on the 17! I'll let someone with a 170 Logic suggest how to clean the bilge. But if it is like the bilge unit on my 215 you simply press on the sides of the unit to free it from the 'cradle' it is attached to then clean out the screen cover then reinstall. Be sure that the screen is covering the pump intake when you replace it. The bilge pump in your boat could very well be different so hang on for some other input.
