Compression performed by dealer as of April 2014 when I took ownership - 1) 150 2) 150 3) 155 4 ) 155
First 10 hours, no powerhead issues.
Now, it has no power and wonât go over 1500 rpm. Starts with no problem. Problem occurred on the water when attempting to get up on plane.
Troubleshooting:
Compression now using my gauge (different than gauge used in April)
Cold â 1) 135 2) 150 3) 150 4) 155 (one squirt of fogger in each cylinder)
Hot - 1) 120 2) 130 3) 130 4)135
Spark good on all four cylinders using a 7/16 inch using spark gap tester
Timing at cranking speed: 32 degrees BTDC
Tested running from remote fuel tank and no difference
Observe fuel to remain near full in fuel filter installed after fuel pump.
I think there is an issue with cylinder #1 but, current compression does not look that bad. Is there anything else I should look for before removing the head?
