ok as some of you know i just bought this and am learning as i go .. i need to know if there is a way to test the trim unit without the ski running the guy said something about pressing the landyard button 2 times then it will go into test mode ? does the ski have to be running for the trim to work ? i am asking because it is not working for me right now. i have not ran the ski yet since i am still going over things with it .. i did get it to fire for a moment but didnt let it run .since i dont know alot about them yet .. also is there a water pump that needs replacing like a boat motor ? is there a fuse box somewhere i need to look at and check ? .. i was trying to find an operators manual on line but only found them for 1998 and newer skis .. thanks
