I have an 02 200 VMax HPDI, no mods all factory. Approximately 800 hours, I've owned since new when I bought my Ranger 518 in 02. I live in Minnesota so it gets used 3-4/week over 7 months of the year. The motor has been in credible for me. I am a little superstitious about talking about how reliable it has been. Over its life, I have fed it 87 octane (mostly) I would say I've used Yamaha fuel conditioner or similar product about 50% of the gas that has gone through it, maybe a little higher. I've always used Yamalube oil. I have changed out spark plugs, fuel filters, impellers, lower unit oil, and had to replace a couple trim switches on the throttle. Outside of that, its never needed a repair or been in a shop for service.....
I am planning to repower this Ranger if/when the motor goes but would like to do what I can to keep this motor going as long as possible. I think anyone in this forum knows this motor is not the fastest motor and the hole shot has suffered with the added weight of 4 31 class batteries mega live target lock 360 more large sonars (and tackle). But I am not racing, I'm fishing. Mostly 300-3000 acre lakes, spend most of my time imaging and on the trolling motor after runs, rarely run too much over 3500 RPM.
I feel like its running a bit rougher late season, maybe that was just my paranoia. I am writing this to ask this group if there is anything you would consider doing to this motor, from a servicing perspective. I've been considering getting the injectors cleaned and rebuilt. Just haven't pulled the trigger because I have been afraid to mess with the motor. Is there anything else I should consider doing to it to keep it going?
Thanks
