    ### Fynspray 65mm Oval-Insert Marine Replacement Impeller for RWB2672 1in Pump

The RWB2675 is Fynspray's replacement flexible impeller for the RWB2672 1 inch pump. It combines eight flexible blades with a special oval central shaft insert. The listed overall diameter is 65mm, the depth is 51mm and the shaft-hole diameter is 16mm. The insert shape is a defining fitment detail, so it needs to match the pump shaft rather than merely sharing the same nominal bore size. The 1 inch description refers to the associated pump size, not the diameter of this replacement impeller.

### Choosing and using this product

Check the pump identification before selecting the service part. The catalogue lists another eight-blade impeller, RWB79B, with the same overall diameter and depth but a half forward keyway connection. That keyed version is a different part for a different pump. For RWB2675, compare the special oval insert with the existing component and confirm that the pump is RWB2672. Do not select the impeller from a shared illustration or blade count alone.

When servicing the pump, inspect more than the flexible blades. Look at the cover, housing surfaces and shaft area, and investigate any reason the previous impeller failed. Reduced delivery may also involve a restriction, an unsuitable operating condition or another worn part. If sections of an old impeller are missing, account for them and have the downstream water path checked where needed before operating the system again.

Isolate the mechanical drive and arrange the water connections safely before removing the cover. Use the current Fynspray instructions for the exact pump, including the approved fitting method, any assembly lubricant and the sealing components required when closing the housing. The impeller is supplied as a replacement component; this listing does not imply that a complete pump or every other service item is included.

After fitting, make sure the pump has its intended liquid supply and carry out a controlled check for leakage and restored delivery. Flexible-impeller pumps should not be run dry. Record the pump model and this part number with the service information to simplify the next replacement. Where the pump is used for engine cooling or another consequential duty, have the completed repair and operating performance checked by a competent marine technician before returning to normal use.
