When making a repair, price is always a relevant factor. Be warned that the cost of doing nothing at all will be high in this situation. The majority of outboard parts are well-built, but some, like the water pump impeller, are made to deteriorate over time. The impeller can be acquired online or at a nearby marina for a reasonably low price. When you do buy the parts, budget for at least the impeller itself to cost the bare minimum. Although buying a whole Yamaha outboard Themostat generally advised, getting just the impeller will probably work just fine if money is an issue.
Even individuals who repair vehicles or other machinery may be misled by the water pump impeller change's apparent simplicity given its high value. By getting the right service manual for the job, a lot of frustration may be avoided as each outboard brand will have distinct repair processes.
