Looking for a bit of guidance. I recently purchased a boat with a 2006 200hp etec that I was told to be "shot". The previous owner had next to no information about it. The motor has only 100 hours and the main problem seems to be low compression in all 6 cylinders(ranging from 50-88psi). Was just hoping someone had a little insight on something that might be causing this that could turn out to not be catastrophic. Thanks in advance.

Hi Whaler,
Please post the engine's Model Number and Serial Number, from the ID plate on the swivel bracket. This helps the experts help you.

Hi, well the basics have to be done first. Check reeds to be sure that those are in good order as well. Get the history report from the EMM and post it up on here so it can be checked out, alot of good info in this report. 100 hrs and that low on comp. hmmm. What oil is in the oil tank- XD50, XD100, or cant tell?

Not the greatest picture of the report but this should be helpful.

First, have the EMM History read and please post on this thread in .pdf format, easiest to view.
We want to see if there are any oiler failure issues.

What is the cranking rpms while checking compression with all plugs out?  Can read with E. Diagnostics software or digital tach.

Check the reeds for corrosion/dirt buildup preventing sealing.
Run cylinder leakdown tests.
If reeds are sealing, pull the heads.  Examine and measure the bores.  May also be severely warped heads from major overheads resulting in head gasket leakage.

Well, that's interesting, other posts did not download until I posted.  Smart phones puke.
.
Lots of WIF water in fuel error codes, injectors may be corrosion damaged.  Excessive nozzle leakage washes oil off cylinder/piston walls and rings, causes excessive wear.  Have the injectors serviced by a professional E-TEC injector shop
Motor only Winterized with extra internal oil protection 2 times in 12 years, not good.

That section was labeled "historical engine faults" I figured that was more of a common problems section.
