Default performance update

Hi guys the motor is getting spark on all six cylinders.
The compression test with all plugs removed and a cold motor were
#2 85
#4 85
#6 85

#1 85
#3 80
#5 85
I then took boat out in the bay and tested compression in one cylinder with all plugs still in the compression was between 95 and 100 on cylinder #2. I can't understand why I was getting 5200 rpm last weekend and then such a huge drop in rpm's. I'm sure the compression was the same last week. Could a failing fuel pump be the cause? Again Thanks everyone for you're help.
