Block off Kits are ONLY for carbureted applications. It is not possible to pre-mix a fuel injected ski, as the injectors will clog.

The following is a general guide covering most PWC models.
First, remove the oil pump. With the pump removed, you have to cover the hole where the oil pump was; you do this with a block off plate.
Install the plate with the gasket, O-ring or silicone to seal it (whichever was OE).
Next, block off the oil feed lines (these are the lines that run from the oil pump to the intake manifold/carbs/flame arrestor). There are a couple ways to do this. First you could leave the lines attached to the manifold, cut the lines and put screws in the end with a cable tie. Second you could use the little block off caps that may come with the plate.
Remember you just got rid of your oil pump and put oil in the fuel, but you do not have premix fuel in the fuel lines. It's a good idea to squirt some oil down the carburetors then start the watercraft on the flush kit and let it idle for about 15 minutes. This allows the un-mixed fuel to clear the lines.
