I bought a 2000 Pantera Classic with a 200hp Mercury 2.5 EFI back in January. This is my first post but I do scan through forum often. Last night when I got back to the ramp I noticed oil on the water around the motor. When I got home I pulled the cowling and I am pretty sure that oil was blowing out of the motor reservoir cap. From searching a few older posts I saw that this isnt uncommon but I really didnt see what the cause was. Will replacing the cap or reservoir fix it? Or is there something else going on that I need to be concerned about?

More than likely you have a bad seal or the cap is cracked. Just happened to 2 of my buddies boats, both running 200 EFI motors. Its just plastic and they do break. 50 bucks or so will buy you a new one. Hope this helps.

I appreciate the input. I was worried it might have been a sing of a bigger problem.

I have a 1999 200 EFI. I have replaced the cap twice in four years. They crack on the side, about where the threads end.You should be able to see the crack if you look when you tighten the cap. I try really hard not to to tighten to tight. The parts guy where I buy mine says he sales a lot of them.

There have been several different reservoir issues over time with cracking molded reservoirs, lines or hoses and finally the reservoir caps. Most of this is a time issue on aging engines, which is not a large percentage of those engines out there. Literally thousands of these engine oiler styles are out there on everything from a 135 to a 225 using these same exact reservoirs and systems. There are also several thousand engines with the same operating system which has different components that function the same.
