Good motors. What you have to careful of is the nylon gear for the oil pump. If the motor has been overheated the gears will fail prematurely. Carbs can require some attention from time to time. On my 175 I have probably replaced 5 set of needles and seats over 30 years. There are tricks to starting them when cold. My ex never could get it. Countless times I had to jump in the boat and start. First pump the bulb until firm (part of prep in parking lot before getting to the ramp), after backing down lower the engine all the way (probably most important), Then turn key and hit the enricher a few times.
