SHURflo Bait Sentry 800 vs 1100: Livewell Pump & Hose Fit Guide

Two Bait Sentry pumps can look almost identical, but their discharge fittings are not the same. If you are replacing a boat's livewell or baitwell pump, start with its identification label and the hose already installed. This reference compares the 800- and 1100-GPH Bait Sentry pumps in the UsedRVParts catalog, including the different original-equipment numbers that may appear on an older unit.

Match the label: aftermarket and OEM numbers

The manufacturer identifies the Bait Sentry 800 as 1700-011-030 in aftermarket form and 1700-010-030 as its OEM model. The Bait Sentry 1100 corresponds to aftermarket 1700-021-030 and OEM 1700-020-030. Reading the entire number avoids confusing either of these with other Bait Sentry or Piranha pumps.

Pentair's published livewell-size guide associates the 800-GPH model with 40 US gallons and the 1100-GPH model with 60 US gallons. These values are selection references, not a substitute for evaluating the plumbing layout, water lift and system requirements.

Checks before replacing a livewell pump

1. Verify the hose barb: the 800 uses a 3/4-inch discharge hose; the 1100 uses a 1-1/8-inch discharge. The larger model is not a straightforward swap into smaller hose plumbing.
2. Compare the number on the pump: check both aftermarket and OEM model formats listed above.
3. Confirm electrical protection: Pentair's installation manual specifies a 5A fuse for the 800-GPH unit and a 6A fuse for the 1100-GPH unit. Follow the full manufacturer's instructions for conductor sizing and installation.
4. Check position and clearance: these are magnetic-drive recirculation pumps intended for livewell or baitwell systems, not pressurized domestic-water pumps. Check proper mounting, plumbing orientation and access.
5. Check the rest of the livewell system: a rated GPH number alone does not guarantee delivery volume once vertical lift, hose friction and restrictions are included.

More marine pump identification guides

If the existing unit is a cartridge-style pump instead, see the SHURflo Piranha 357 pump and cartridge reference. For other recirculation components, the marine livewell pickup and cartridge guide explains the types of parts to identify before ordering. For a bilge pump rather than a livewell pump, use the Rule bilge pump identification guide.
