I'm looking at a skeeter with a 2000 150hp vmax hpdi. How do I check the compression on this? Also, how long would you expect this motor to run strong before needing a new powerhead or rebuild. It has been used about 1-2 times a week since new, but well maintained by both owners. It still runs great and has no obvious signs of problems, I just want to know the health of the motor and enable my self to plan ahead. Thanks.

when doing a compression test on any DFI or EFI motor its imperative to disable both the fuel pump and ign system.
after that open the trottles and crank it over about 5 cycles with all plugs removed.
should be within 10 PSI bank to bank.

Thanks for the help. This is a great forum. Anyone out there with any strong likes or dislikes about this motor? Longevity?
