I am thinking of buying a like new 2005 Yamaha 20 HP 4 stroke motor, I had a 25 Mercury 2 stroke that ran great and had more power than I needed but the fumes and mixing the oil finally got to me. Plus it used about 6 to 8 gallons a day on me. What I am hoping for is that the 20 Yamaha 4 stroke will not disappoint me as speed goes and I am hoping it does a lot better on gas..... Any feedback will be great..am I making a mistake.....I do a lot of trolling 6 to 7 hrs a day..... Thanks Mike
