Greetings, I have a BF75 with the standard low temperature “makes-oil” problem if I run it at low RPMs (trolling) for longer periods of time without intermittent high speed runs to raise the engine temperature. Normally, the way I fish is not too problematic as I fish a large lake with large expanses between trolling structures. Last weekend, I fished with a friend and used different patterns, and the outboard made a significant amount of oil. I have three questions on which I’d highly value expert input:
- How much extra volume is sufficiently large that the extra volume is going to be problematic, and has my extra volume reached that threshold? Please see attached photo of my dipstick for estimate of how much extra oil volume my outboard has right now.
- If the volume is greater than that threshold (or should it get there in the future), is it okay to just drain some oil until it’s below the full-line and use as is? Or, is the effectiveness of the oil sufficiently decreased by the fuel that is the extra volume such that I need to do a full oil change.
- In an attempt to minimize the amount of oil “made” I do more “running around” (at least on some days) than I’d prefer, and would like to only do so as little as required. What is the temperature range to avoid (I get temperature data on my Lowrance via a NMEA network)?
