I was in the same place earlier this year TB. I have a Tracker 1542 that's a couple of years old. I ended up finding a Tohatsu short shaft 9.8 hp 4 stroke. It will push 2 adults and gear against 2 gens on Caney Fork @ 15mph. On the lake it comes in around 19mph per my iPhone speed test App. It is a little cold natured in the winter, I try fish it every weekend of the year pretty much if possible. On 25-30 degree mornings it takes about 4 pulls. Once warm though it will start on 1st pull. I run Star brand ethanol treatment thru it as specs call for on bottle. Very happy so far with power and reliability, I fish with my kids a lot and speed is not a priority.
