Re: 90 Yamaha 4 Stroke Experiences?
I have a 2006 Yamaha F90 on a 16' homebuilt runabout. The boat has a 20 degree Vee at the stern and is built heck for stout. I frequently go 30 miles offshore in the GOM, but I do have to pick my days so to speak. The performance I've gotten out of this outboard has been stellar. The only problem that I've had with this is what I have caused myself. I located the fuel tank vents on the sides of the boat. That caused the ingress of saltwater into the tank. Add a good gulp of saltwater to ethanol based gasoline and you have a problem. I moved the tank vents, cleaned the mess out of the fuel system (that I caused) and have had a great couple of seasons. This engine is strong, smooth and quite. I even installed a radio in the boat after I put on this engine. Just keep the fuel clean, don't over-prop it and keep the maintenance up. I'm really pleased with my purchase and can honestly give this engine a good review. Hope this helps - Woodnaut
