    Cons: cost
    Pros: Quiet, efficient gas usage, reliable
    I have the F115 model and have put over 400 hours on the engine. It has run flawlessly and is very quiet. In fact most folks that ride with me the first time comment on how quiet it is. It also is very good on the gas.

    Maintenance has been a breeze with oil changes & lubs every 100 hoiurs and few other routine tasks like check the feul filter, zincs, etc. the only maintenance needed to date.

    I have the 115 and I am complately satisfied. I bought this motor because of their reputation and I haven't been disaapointed. Starts easily and runs so quiet that you can hold a normal conversation at full throttle. Awesome.
