i think whoever is selling it has given you some wrong info, i can't see Vmax being on a 25hp engine as it strays from what Vmax typically means....happy to be wrong though!
This is why I have asked the question.
My last boat had a Yamaha 2 stroke, 200hp V6, and I was under the impression that the 'V' series applied to the the V4,6, type engines.
I am interested in an engine for sale, and I posted in another thread asking questions. I now have the serial number, and according to all the Yamaha charts available, it translate to a 'Vmax' series...!
I am having trouble getting the picture uploaded, but the serial is:-
61R S 0058828
So, if you cross reference that with this chart.....
