block off

Hi so i have a 95 xp, i want to do something with the oil injection pump because iv read on here they are not reliable. Should i replace it with a new pump or should i just get a block off kit and run premix? also how hard is it the replace it or do the block off kit? what are the pros and cons...

I know , another premix question , But I removed my oil pump and went with the block-off kit. I know the pros and cons to it. My question is if I run Seadoo X-PS full synthetic premixed in my gas , can I run the "Normal non-synthetic mineral oil to the rotary valve oil bath without issues...

how do I block off the oil on my 787? do i need a kit ?
