Hello,<br /> I'm trying to find out if a 1995 Johnson 90 hp has 90 hp at the PROP or powerhead. <br /> It makes a lot of difference in final performance. A 1991 Yamaha 85 hp I tested on a boat gave me poor results. A dealer told me that it really delivered 70 hp to the PROP! Hope you can help. Thanks from ChiliBill in FL
