Wondering how long and how well Yamaha supports their products (especially on limited run models) via parts years down the road? Reason i ask is that the ('98) B115W i own looks like it was only in production for two years. Power head and many of the parts come from the 6N6 or 6E5 groups and seem to be from a more standardized Yammy parts line - but the upper and lower case is a 66Y and appears to be totally unique. I'm sure there may be cross-over applications on a part-by-part basis, but in several cases i think the 66Y is the only part group for this motor. Just thinking if i were ever to lose a lower unit (knocking wood) down the road that parts might not be available? Just wondering about experience with Yamaha and the odd ball models and availability of parts?<br /><br />Thx!
