Specs At A Glance

Good To Know

Q: Is the impeller included with this housing? A: No, this listing is for the jet pump housing only, so the impeller, wear ring, and seals are sourced separately. Your existing internals can be reused if they measure within spec.

Q: Does this fit both the Exciter 270 and the 1200? A: It is listed for 1998 and 1999 Exciter 270 and 1200 boats, though pump assemblies can differ by serial number. Check your original part number against 65A-R1312-00-00 before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
