I have a SX190 with a 150 four stroke. It will jump on plane in 3 sec. Hole shot? I dare to compare it to any other motor. You must be looking at a SX180. With a 115, I doubt you will hole shot as quick as my boat but I would not hesitate buying it because of the hole shot. And at 50+MPH my buddy can hear me talk.
Maintenance? 2 quarts of oil $5, filter (expensive) $22, gear oil $7, fogging oil, $5, total $39 for the do it yourself'er. When you fog a four stroke, you just take out the plugs, spray some fogg in them, crank it without the plugs in it, and that's it. Put the plugs back in and you're ready for next year.
I love my Four Stroke!
