    Upgraded impeller, what next

    I upgraded my impeller on my Sportster LE DI with the 951 DI engine. It made a big difference in the hole shot and midrange of the boat. What should I do next to squeeze out some more performance out of the boat? Is there an air filter mod for the 951 DI?

    You can do any of these. Go with the Complete Level 1 Package and you're Boat will be a Rocket compared to what it is now.

    Which impeller did you go with? I'm considering losing a bit of top end for better hole shot and towing grunt. Good to hear you had positive results!

    I went with the concord ST-CD-14/19, which was the impeller suggested by impros for the boat. The low end and midrange improved and I don't think that I lost too much on the top end, its hard to say since the conditions were not the same the last few times I've taken out the boat. Maybe 1mph.

    I also put in a new wear ring from Seadoo, but was surprised by the amount of clearance that the new wear ring had. Looks to have about .020" clearance around the impeller( solas impeller and stock impeller). I expected a tighter fit.

    The level one kit from ppg looks really good, but will it really make a big difference. They say that it will give 2-3 mph increase for a ski, but will it make a noticable difference in a 1500 lb boat?

    I think it'll make a big enough difference that that you'll be happy. Shoot them an E-Mail and ask if they've ever installed it on a Boat, or gotten any reviews from customers that have them on Boats.
