    2011 225 vmax hpdi series 2 compression and maintinence

    What should the compression be on these motors? I'm about to have a compression test done on one I'm looking to buy and curious as to what it should be at.


    also, this motor has not been ran much at all since either late '13 or '14. Pending good compression numbers I will change all the filters, drain all the fuel, change the lower unit oil and impeller, pull the fuel lines off to inspect the inside, and send the injectors off to be cleaned/flow tested. Is there anything else I need to do or look out for?

    Its average around 120 psi. I think within 10% - 15% highest and lowest is safe.
