I dont work in the marine sector so I never hear about any of those issues. Everyone I know that has swapped to 4 stroke has been happy with the swap, including me. That being said, I only run yamaha's so that may be why I am so biased.
I talked to the Rileys yesterday. they had two sunk boats, a lost kayak and had to do a water rescue at daylight. Also not seen in that pic at buffalo city is a truck that was parked there and was underwater.
you wont find much info about it online really. its between the brazos and the colorado rivers in texas. Mainly a winter time fishery. the cedar lakes to the west and cowtrap lake have the highest concentration of redfish in the state according to shocking data I found from TPWD. Honestly if you live in south LA its not worth the drive since you have Venice in your back yard.
