I promised Darrel "docofthebay" to check fuel consuption of my 3208s at low rpm.
We finally had some good weather and fair sea last week end, so I was determined...but... I had a problem!
At 2500 rpm starboard engine was using some 15% more fuel than the port one and I was doing only 23 kts (instead of 25-26) with a perfectly clean bottom!
Then I tried full steam, the port engine reached 2800 and the starboard only 2700!!! The only viseable difference was some more smoke as the boat got into plane... smoke normal once on plane, i.e. very, very little!
So, this afternoon I have Caterpillar aboard... any idea before I face the mechanic??? :huh:
