Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • Looking for guidance with 245dl problem

    I'm hoping get some suggestions on what could be causing a problem I'm experiencing with my 2003 Osprey with 245dl.

    When running wide open I typically get 3900rpm, but lately it drops 600-900rpm for no apparent reason. Periodically, but then at comes back up. The lag will last anywhere from a minute or two and the climb back up or it can last 30 minutes.

    I've recently changed the fuel filters and air filter after the problem started.

    Any suggestions are really appreciated.

    thanks.

        I can find the 245 but not the VP 245. VP uses model numbers like TAMD 41, MD 21 and 22, etc. Maybe KAD300

        In any case, the most probable cause for a diesel to loose power and get it back is weak fuel lift pump, fuel line leaking, waste gate, governor. If you have digital throttle this could be another area to look, but my guess is you have cable control

          Alldodge, thank you. You're right I'm not sure on the model of the engine, but it's a 6 cylinder Volvo penta approxamently 200hp.

          Of the the possible causes you mentioned could/would they be occurring intermittently?

            The reason I need to model number is because I don't know how the motor was configured. What components were used (turbo, fuel pump, etc) and if there were any service bulletins out about a given model. Using D6-330 and KAD-300 for reference

            The good thing about a diesel is it you don't give it enough fuel it doesn't go lean, it just slows down, no harm to the motor. To much fuel and it puts out black smoke but doesn't make much more power.

            Your statement of it would do it from 1 to 30 minutes with no rime or reason. If the lift pump is having trouble it could vary at times. Thinking it has a mechanical lift pump. If the pump is having trouble from a line restriction, being weak, vent line clogging which draws a vacuum on the fuel tank, or other. Electrical sensors which may be reading an issue. Without knowing more I would place a fuel pressure gauge inline between the fuel filter and injection pump. See if pressure falls off during these times

            Hey Scott Danforth have any thoughts?
