    A GP1200, 760 or 800 will bolt right up. With some modifications a GPR pump will bolt up. Bigraider and addicted can help you out if you decide to go the GPR pump route.

    Thanks for the help!!! Will I have any power problem using a bigger pump? If I am correct the 760 pump is 144mm and the 1200 is 155mm in diameter also the pitch of the impeller has to be different.

    I,m trying to get a ski i bought with a damaged pump on the water, but I live in Canada so getting something shipped to me isnt the easyest. I will have to piece something together if i want to save some $$$$$ plus stock isnt always the best in alot of cases.

    I think you are correct in that the 760 uses a 144mm pump. Fortunately, most yamaha pump housings interchange. you will probably need to swap the driveshaft and bearings and get new seals unless you get a pump off the same ski. Check out the link on the left where it says order oem parts. you can look up the different years and models and compare part #'s to be sure.

    Unfrotunately for me I have nothing to work with I need all new/new to me parts. The intermdiate shaft is stripped, drive shaft is cut, intake duct is craked, impeller/wear ring are no better than the drive shaft but on the good side the engine runs mint and the hull is clean...... enough

    A Waveblaster II (760cc) uses a 155mm pump so you can run a 155 too. You will lose some topend, but it will help coming out of the hole.
