Dear All,
I have 1995 Wellcraft Martinique 27 with single diesel Volvo Penta KAD 42.
Normally boat sails with 23-26 knots gps speed with 3000 - 3300 rpm with maximum speed of 33 knots at 3500 rpm.
Last week performance of the boat was very good but this week I faced with a strange problem.
At marina, in neutral (N) gear, when I give throttle, engine goes up to 3800 rpm which is quite good.
However, at the sailing, when I give full throttle engine stucks at 2000 rpm with 8.9 knots gps speed and never go more.
Also there is no any white or black smoke.
I have removed turbo, compressor, intercoller, injectors and cleaned them and connect again however nothing changed.
I checked the quality of the diesel also it was good.
I checked cable/wire of the throtte arm and it was also good and normal position.
What could be the problem ?
Where do I have to look and check ?
Waiting your helps and recommendations.
Kind Regards
