2005 310 Signature in Boat Talk Posted December 3, 2020 On 9/17/2019 at 6:41 PM, Steve24 said: So my Mechanic pull all the injectors. 6 were plugged and the other 10 were very dirty. Had them all cleaned and flowed, new screens and new O-rings. Took the boat out on Saturday. No change. Very frustrated. He said he is going to do a compression test next. The injectors needed to be done anyway, so it is money well spent. Just do know what the #$^% is going on with it. Hoping it's something simpler that an engine re-man. Time will tell. I would a set of Racor filters then. I did with no problems pulling fuel though 2 filters. Your filter should have stopped the junk getting that far.
