have a 1999 Yamaha 150 TRP on a 18 foot Shallow Sport Bay boat. I purchased this boat used and have had it for two years.
The fuel economy is terrible. This boat uses more than four times more gas than a 1995 21 foot Cajun with a 130 Johnson I had before. I also have a friend that has a boat just like mine, only newer, that is much more economical than mine. When I shut the motor off, there is a slick of raw fuel in the water.
Any comments or suggestions would be appreciated. Thanks for reading this post.

Sounds like bad fuel pump diaphragms. Check them out before you pop a piston!!
