The engine info (DF 140 Z 14002Z-110301) This engine was soft grounded last year and set of the temp light and rev limit light. Boat was towed to dock to keep from causing damage. Water pump kit was installed and engine showed no signs of problems thru the end of last season. Boat sits through winter on a trailer and when put back in water this year wants to overheat, temp and rev light came on, first trip. Checked and replace just impeller, the one removed showed no signs of problem. Water test and still have same over heat results. Took it to a certified Suzuki repair shop. They said they flushed the engine with lower unit off and thermostat out, replaced the water pump assembly, and thermostat(s). Engine still runs with same overheat results. I noticed today when at idle the tell-tail pisses but above 1500 stops pissing. Bring it back to idle and it starts pissing again. Why would it **** at idle and not above idle? Shop said all they could suggest at this point is to disassemble the power head and clean it because it must be clogged. Over 4000 rpm engine runs overheats fast, maybe a 1/4 mile. Below 3500 rpm and it will go several miles before overheating. If the engine was partially clogged would the tell tail act the way I described or would it possibly **** better at higher rpms and stop pissing at low rpm's? Any ideas? Thanks in advance.
