Looking for some feedback... please!
Looking at a used boat that has 200 HPDI's with 1300 hours on them- what is opinions on the HPDI's?

    HPDI motors will go down in history as one of the most reliable,bulletproof motors ever produced ! I highly recommend you contract the services of a qualified individual/shop,to check out the motors - run a YDS report and a check out...very important !
    can we please stop using the word ISSUE ? it's a PROBLEM

    Possibly the best 2 stroke Yamaha ever made.  Those motors require a lot of filters that need regular servicing ( annually, etc).  I've run a pair for about 680 hours over 12 years and have had only 2 repairs needed- dead voltage regulator and VST fuel pump.  Get a YDS report.

    My mechanic says the 200's are practically indestructible but the 225 and 250's are an issue. Said corrosion and overheating is the issue. Never owned the big blocks but just passing along his info. He worked for Yamaha for 30 years before retiring and starting his own gig which he"s been doing for 15 years.

    As stated the 2.6 liter block is a great motor, the 3.1 have lots of issues.

    Thanks for the responses- much appreciated!!
    With good & normal maintenance- how many hours might be expected with the HPDI's?

    Mine (a 150HPDI VMAX) is now in its 19th year, if that helps.

    there's a reason they're not made anymore.

    Because they were too good and weren't getting replaced.

    And Yamaha decided to make a marketing/ manufacturing decision to not sell 2 strokes in the US anymore, I have 600 hours on a 2005 HPDI 150 and it has been flawless.
