Had the boat to the dealer for

Had the boat to the dealer for testing with no luck.
Says the computer readouts are normal. Did not water test. I did and this is what I found
Engine starts and runs but seems to develop only
70%power and not smooth. Have redone all filters air/water sep plugs lines etc. Runs marginally not misfiring but blah does not develop full rpm.
Any ideas out there ... Hate to pay another 300 bucks for nothing

"JPW,
We had a similar problem with one of these, comp checked out fine but it turned out 1 injector was faulty. You can check this without the diagnostic software by momentarily unplugging 1 injector plug at a time, rpm should drop on all 4, if it doesn t, you have found your problem."
