i was test out my 1997 challenger the other day and ran the garden hose to it. i am new to seadoo's so i turned the hose on first then ran the engine, i now read that i wasnt supposed to do this that the engine must be running first before and after turning off the hose. did i do any damage? i ran the engine for 10 minutes on the lake after that and it seemed fine..anything i should do
