So my dock neighbor bought a 1998 - 4100 express cruiser Maxum last fall. He has had nothing but problems getting it on plane. He has put $10k into it and that includes props redone, bottom paint, new injectors, and the boat won't get past 2600 RPM's. He has replaced the fuel and included additives. He has fresh fuel. Had the air systems all cleaned out. I am not a diesel guy. Just curious if this is normal. Boat only had 450 hours on it. The thing is both motors have issues getting past 2600 rpm's but the bottom is clean. The boat won't plane out. It has been intermittent and it did at one point get on plane. The Cummins mechanics just keep wanting to replace parts. They are suggesting a new head gasket now. He is frustrated any ideas?
