Ok, my last couple fills were not normal to what I was burning last season.
I am now around 40 gallons higher fuel burn on my port motor.
I have made many post about my port motor lately reguarding fuel stop solonoid, boost is off (possible gauge) and transmission pressure which is ok when tested with mechaincal gauge.
At first I thought it was the burn from the diesel furnace over winter, then I filled again after a trip and I was down almost 40 gallons.
the prop was re conditioned last season and 10 pounds of metal was shaved off after repair, but it still turns rpm to proper 2500 .
Motor is TAMD71B Volvo
I have no noticeable soot issues either?
maybe someone syphon some fuel??

any ideas here?
I will be taking a 2 week trip soon and watching this closely.
