We (Nichols Outboard) have been building them for years, plus I worked for and still do work for Yamaha Outboards. If I can help you or you have any questions give me a call. 423-451-0125
I strongly second Nichols, Just had mine rebuilt by Paul and it's great, Had a little hiccup and Paul dropped everything and took care of me instantly. Couldn't be happier with Paul and his staff.
Thanks guys- Im gonna give Paul a call. Its at a local dealer now but they havent really communicated well their plan on repair. If it results in needing a rebuild I will get with Paul.
