Have Boat Questions? Ask a Boat Repair Expert.
Hello, my name is***** will assist you today.
Would you please post the serial number of the engine?
What all was done in the service of the boat?
When you are underway and the power is lost, is there also an alarm?
Do you have a multimeter?
First inspect the plug wires fro the top 2 cylinders. The temp senders are really close to the plugs. Sometimes the sender will rub a hole in the boot. If they are good. Preform the test on page 3 of this bulletin. Do this to all 6 coils. Somewhere you do have a bad one, just need to locate which one it is.
Sounds good. i willl be here for a few more hours tonight and most all day tomorrow.
Hello, when you had replied, I had already logged off.
Did you look at the boots for the top two spark plugs? If they are grounding out, there wil be black marks on the outside of them?
Which spark plugs did the shop install?
Do you have a gauge that can read fuel pressure of at least 40 PSI?
The alarm in Neutral, is just that, a neutral overspeed warning, it does activate at 2500 RPM and is normal. I am thinking that you have a failed grommet in the VST, a gauge would tell us that.
Yes there is. You can open and inspect the grommet on the top of the high pressure pump. Part 30 in the diagram.
No worries. On the weekends I am on here most all of the day.
If the grommet is the issue, you will be down on power and could run the motor lean. That would be the main issue.
