I recently blew up a 2003 Johnson with VRO oil injection and was told at 10 years I should've replaced the pump or bypassed it and started mixing my gas and oil (nice to know now!). I just bought a new to me boat with a 2006 VMAX HPDI 175. The motor only has 32 hours on it, but considering the age is there anything I need to know about? According to the research I've done the VMAX HPDI seems to be a good motor. Thanks for any input.
