I have a single 250 Yamaha saltwater series that I am planning on trading in. It has a brand new powerhead and stainless steel prop. It is a 2002 V6. It is still on the boat and works great. Send me a line if you are interested. It might be newer than what you are looking for.
I have a 1990 250 Yamaha Saltwater Series Engine with a brand new powerhead installed March 16, 04. It has about 11 hours on it. I also just replaced the prop with a new stainless steel Solas prop. I have $6400 invested in this motor right now and it runs great. I am about to purchase a 4 stroke and need to get rid of this quickly. Please let me know if you are still interested.
