Just replaced mine on a 2002. Not a big job, about $400 for the heater.

There's definitely a blockage or it's airlocked somewhere. Mine will get so hot that it's dangerous.

The manual says it should heat to 140 degrees, but my electric heater only gets the water to 103.  But when heated with the engine, it only gets to 93 even after running the engine 20 minutes (Yanmar 3GM30f).
