LS3/Scott Pump Performance Information

Postby Great White » Mon Feb 02, 2015 2:56 pm

Is there any performance information available on a Scott/LS3 combo?

How would that combo work in a 21'er?

Hi this is one of our most popular combos the LS3 in stock trim or the 485 package works great - in smaller boats we run 15 deg front impellor 16 rear 112 nozzle and turn them wide open at 5500 RPM in the bigger boats 18 ft upwards we run a pair of 19 deg impellors with 112-114 nozzle and turn them wide open at 4800-5000 this gives a better cruise speed at a lower RPM.

To back up what the manufacturer just said, Yes that combinations works excellent in 21 ft. boats. As you can see by those numbers we like to let the LS3 rev a bit more than some engines. We have found that those new LS engines really like to rev a bit to be happy. If you over impeller them and "lug " those engines it can cause some internal problems that become rather expensive.

Thanks guys.

At 5000 RPM is there a top end speed I could expect on a 21' CW Storm?

Thanks,
