Location: Maple Grove, MN | I don't think the 115 Opti had power head problems. I believe the only Optis that had trouble were the large 175 HP and larger models with 6 cyclinders. The problem was with cyclinder 6 running to lean. I believe the 115 has 4 cyclinders and so it doesn't have that problem.
No motor is perfect though. Sometimes my Yamaha adds gas to the oil if I troll to much in cold weather without warming the motor up enough. I find that its important to get the motor warmed up good by hammering it a little before a trolling run and its best to hammer it a little between trolling runs. The motor just seems to cool down a little to much at times in cold weather and doesn't always burn all the gas. The unburned gas leaks down into the oil pan and then you just have to change oil an extra time. Its no big deal. Its easily preventable and just something to be aware of.
I plan to run my 2003 Yamaha for many years. Based on my experience so far, I should be able to.
Good luck with whatever you buy.  |
