Outboard is Cooling
The repair kit arrived on time as scheduled. The kit contained everything needed to replace the Mercury 175 OptiMax impeller. The engine is cooling now and we are back on the water without issue. Easy replacement.

So far good
Style: R-S202BL, Configuration: w/o Wire and Plug
Very satisfied, so far. I've only used tuner & cd / dvd player. Have not tried Bluetooth yet. But sounds great with 2 Yamaha 200watt speakers and 2 Realistic Allegra 150watt speakers. 👍👍
