i seem to see alot of boats with setback pumps and rideplates/shoes. i was curious if this needs to be done on my boat . currently my pump is in the stock location. i have an 17ft v bottom that i will be doing some bottom work on this winter. my boat seems to porpoise alot at higher speeds. i have a droop and diverter currently with no ride plate yet. my bottom seems to have alot of hook in in, is this the cause of my porpoise problem or is this caused by something else? would a ride plate off the transom be helpfull. most faster boats i see are setback. anyone have a non setback pump and running without porpoise issues. thanks for any help on subject.
