I recently replaced all fuel filters on both hpdi 200's. However i either have bad fuel or something in the tanks .
The boat ran really well while Ken Lahr was here (3 days)but on the day after he left I couldn't get my portside mtr to get past 3500rpm.
I removed the portside 10 micron filter and there was no sign of water but a gelitinous substance ran out of the filter.
Q1 any ideas what this would be ? I also had just put a measure of fuel cleaner and decarboniser in the tank before the trip. The motor had consumed the whole tank at this stage and i was nearly at the bottom of the main tank.
Q2 these yamaha filters were $50 each and are virtually brand new. Can they be cleaned?
Q3 The local Yamaha dealer and his mechanic of 20 years has never heard of Ringfree and does not believe it is part of Yamaha warranty policy . That is why i used the fuel conditioner he recommended by Evinrude.....
