Note:

This product is delivered in original equipment manufacturer (OEM) quality. It is not the original product from the manufacturer.
The life of a seawater and impeller pump is limited, even if maintenance such as replacement of sealing and impeller are carried out regularly. The reason for this is corrosion, which is caused by the constant condensation of the pump even if the engine is at a standstill. as well as material removal due to erosions as a result of the high flow speed of the seawater inside the pump housing. OEM quality.
Often small but steadily increasing leakages, usually at the bottom of the housing, are signs of a pump's demise. At that point. you should think about a replacement.

Hello everyone! My motor is a Yanmar 3GMD, an inboard motor from a Dehler Optima 98. This is suitable for Yanmar 3GM, but not sure that it will fit the 3GMD. Did someone use this saltwater pump in a 3GMD? If so, does it fit perfectly or is there any modification to do? Thanks in advance! José Romão Valente [email protected] +351 910 174 720

Where can I get the 13mm nozzles at the proper angles? (Aren't they 90 and 45 degrees?). I don't see any for sale on this website.
