I have a Honda 20003 bf15 d short shaft Ineed to change the water pump I have removed the 5 bolts that hold the lower unit it on but the shifter is steal hooked up how doI unhook that?
Please get the workshop manual. From an imperfect memory it should be in forward gear to expose a link - but I could be confusing it with other brands. This brand has a known issue with the water pump if ever run dry as both the impellor and the housing can be damaged instantly. The pump should always be replaced as a full assembly, housing, seals and impellor, as detritus can easily block water galleries and that requires extensive work to remediate. The thermostat should be checked and replaced at the same time. Worn and damaged impellor material can easily end up through the block, head, thermostat etc. and that must be checked for as well. The lower cylinder can be down on compression caused by local overheating due to this and mud, sand and corrosion reducing water flow. An engine that very much must be flushed and looked after after all use - that includes all the larger models with this brand. They are quite a good engine, but seem very heavy for the output to me - particularly compared to lifting a two stroke on and off....
