The boat seemingly runs excellent and on plane at 3,500-3,750 RPM with an average-above average load of fuel and people on board. If you are running across a lake of glass the issue simply doesn’t occur. When you cross a wake and get a bit of a shudder in the boat the port engine drops from operating RPM down to about 1,500 RPM then immediately goes back up to its set RPM. Here is what I have tried so far…Before I put the boat away for the year oil, oil filters and fuel filters are normally replaced.
However… I kept purchasing fuel water separator filters every year. In all of the time I have owned the boat I have only changed those filters one time. OOPS!
I found the error when I was cleaning out a cabinet. I pulled out 3 sets of fuel water separators.
SO… I figured it would be a worth while endeavor to start with the filters and test the boat again. The test ultimately failed as the wake hit then drop out symptom happened again.
Now I have been out of commission the entire month of September 2018 due to work then 3 weekends of illness.
Here is what I’ve been told to try next:
- Check the spark plugs (tight/lose)
- Check the spark plug wires (tight)
- Check the wire going into the distributor (firm connection)
- Check the wire going to the ignition coil (firm connection)
- Perform a tuneup
- Fuel Pump (which i do NOT agree with)
The boat comes out October 18, 2018. I am going to try to check all of the plugs and wires (items 1-4) before haul out day. On haul out day I am going to test the boat over wake again. The last tune up was performed by a VERY qualified mechanic when I purchased the boat so I knew I had a good tune up starting out.
I think regardless of my test results the boat is going to get a tune up after this season.
What are your thoughts?
