Dad had same plane. that evo is best used a paper weight, had numerous probs with it, kept geting sent back. in the end we just junked it and threw a saito 82 on the front. never lookeed back

if you want to use it later for sport i would recommend a 4 stroke, imo u cant beat them unless u want to go fast. price maybe an issue on the saito 82 but it is a great motor with a wide array of appliactions
