My Invention "Last Drop Oil Extraction Systems" for the Yamaha 1.8 SHO motors and the MR-1 marine engines for the FX HO and VX waverunners was debuted at the 2013 World Finals in Lake Havasu Arizona. Check the Riva web site under 'New Riva Products' for detailes and pricing or give Riva a call.

Pre-Patened design.
Imagine all of these performance benifits!
1- Removes 99% of contaminated oil.
2- Better engine performance and speed.
3- Complete oil changes helps with clutch life.
4- Helps elimate engine sludge.
5- Saves time and money because of less frequent oil changes.
6- Submerged engines can be pumped dry of its oil and water.
8- A mechanic's dream for quick oil changes it the pits.
9- Sturdy Stainless Steel and Aluminum construction.
