Hi, I have a 87 ericson 34 with a universal/kubota engine, 25xp, the engine will run on the the dock at around 1500 rpm it will idle all day, put when I put it in gear then it slowly sputters and die, I changed both filters, my gut feeling is that the tank is full of crud or something, and plugs my new filters very quickly, had to get towed in last time. Any thoughts out there? has anyone ever removed that tank, seems like I have to cut the boat apart to get it out.
