Ok, this is driving me crazy but I know it can't be too hard. I have two 2002 Sea GTI LE's. I can do the fogging as well as the silicone spray on the outside of the engine. That looks pretty simple. The anti-freeze kind of scares me simply because I haven't done it before. Here's what I have seen on you-tube (yikes!). Undo the hose that is on the upper, outside part of the engine block (the one that is more in the center of the craft, not the hose next to the "body" of the sea-doo), connect a garden hose/funnel, pinch off the clear drain hose that T's and runs along the floor below engine, pour marine grade/rv anti-freeze in the hose I attached until I see it flowing through to the bottom hose. If I run antifreeze through the block do I need to keep the hose pinched? I can, it just doesn't make tons of sense to me. Help me out. I am in the crowd that would prefer NOT to pay over $100 for work I can easily do myself. Thanks, Greg
