I finally made the plunge and bought a like new Yamaha F115 with 32 hours on it for 5,500.00. The deal included all controls,prop and digital computer readout tach head and the price was right. So in making the transition of removing my Mercury 115 and all the controls etc. I naturally wanted to install a new fuel line and filter assembly for the Yamaha, In doing so,I found some pin holes on top of my new, I replaced it ten years ago" fuel tank. lol!! Time flies. No biggy.....so it is tank time. My question is? Any other member out there with a circa 1986 200 Osprey that has replaced the aluminum tank with a Moeller and can give me the Moeller replacement part number? It would make things a bit easier as I don't want to do this again in 10 years. I'm the type of guy that hates change.....Maybe that's why I stuck with that inline 6 - 115hp Mercury for so long?
