I am buying a 2005 225 hpdi with 52 original hours and supposedly the original powerhead. Going to get a compression test and the history pulled off the computer. I want to check with Yamaha to see if it has the updated oil pump on it. Is there anyway to pull that info up through Yamaha or is that dealer access only? What do you guys suggest needs to be done as far as maintenance to make this thing go as long as it can? Thanks
