Yamaha 200 HPDI Question - The Hull Truth

timoa · 11-13-2008, 07:47 AM

My 2001 200 HPDI's are starting to smoke excessively at cold startup. The engines have approx. 600 hrs on them and both are showing the same conditions. Other than that they run perfectly, plenty of power etc. I change plugs at 150 hrs and do all the normal maintenance items. The only thing I have been neglegent on is the use of "ring-free"....simply because of the cost. Recently I changed the oil pump on one engine to note any differences- none noted- both oxygen sensors have been changed and subsequently cleaned..... any ideas??? Thanks Frank

If ya cant afford to run ring free then its going to smoke

....Use di(direct injection)oil no penzoil.
