I bought a 2005 yamaha HPDI four weeks ago, i have worked day and night to prepare my new boat and engine, but the two trips i have been taking have been failure with LOW RPM
1) When slowly building RPM the engine stops at 2300 RPM
2) When have a moderate acelleration the engine stops at 3000 RPM
3) When kicking the throtle the engine stops at 4000 RPM
4) When idling i get 5000 RPM +
Sometimes the engine completly stalls but sometimes it also goes down to 500 RPM when it starts again and build new RPM and again it stalls.
I have been checking all the connections of the fuel line, tighten them and drained the 10 Micron filter (Brand new) I also tryed to connect the fuelhose directly to the fuel tank without using the seperate fuel filter. And i`ve tryed to connect to an original yamaha fuel tank with original fuel cable without any results. I`am currently using 8mm hose all the way into the engine.
When i contacted the seller he told me to use 10mm.
The fuel filter is also full of fuel as it should be.
I have tryed the engine two times in water and the first trip i tought that it may have been the connector from the seperate oil tank to the engine, because i didn`t have it and drove the engine just with the 1 liter tank onboard. But when istalling the cable it didn`t help i`m kind of out of ideas.
May anyone help me?
