I am currently shopping for a used boat and have identified one with a '98 Johnson FICHT 150 on it. In speaking with a local dealer, they have cautioned me to stay away from this engine. Apparently there were lots of problems when they first came out. The dealer has since dropped the line. The current owner tells me that all manufacturer updates and upgrades have been done. I am new to boating and I do not want to make a big mistake that will either cost lots of $$$ to correct or impact the potential resale of the boat. Any advice?
