    Yamaha Wave Venture 701 vs 760/1100 (pump Question)

    I recently purchase a very low hours (under 100) Wave venture 701 that had a locked pump. I have since pulled the entire pump tunnel and pump assembly because things were so jammed I was having a heck of a time getting the pump removed otherwise (and with winter coming I just wanted to get it out and onto the bench). A friend of mine has an Venture 1100 with bad motor that he is offer me for parts, but before I take him up on the offer I have a few questions for the group…….

    I know that the majority of the 701 skis run the 144mm pump and that the 760/1100 skis run the 155mm pump. With that being said, I realized the physical size of the 144&155 pumps are obviously different but is it possible to do a complete pump swap (pump tunnel to steering nozzle) or do the two pumps have different mounting applications. Any help is greatly appreciate…….

    I realize that the Raiders and Venture all the 6 motor mount points to accept with a 2 or 3 cylinder motor, so does that mean the hulls can accept either the 144 or 155 pump?

    Technically, 94 (purple) raiders don't have the extra bosses for motor mounts.

    144 venture/wr3 pumps can be had fairly cheap. I probably have a few. Or you can probably repair the pump you have fairly cheaply. I hate wrenching on ventures. There just isn't any room. Silly how they built such a huge ski but left no room to work on them. I really wouldn't want to bother trying to swap the driveline like you're suggesting, but it is doable.


    WHEN IN DOUBT, GAS IT!

    Yeah, I'm an @sshole, but I'm not a complete @sshole.

    The 98 and up venture/xl700 use the 155 pump with a very low pitch impeller.

    I'd rebuilt the 1100 enginge before the 144 pump. It may just need a pistion. Like said above parts are cheep. You said "it's winter" rite? Take the best parts of the two and make one.
