This pump was fitted to my Yanmar 3GM30 and is completely satisfactory. Its price at SVB is much lower than that charged by Yanmar. I am very satisfied.
The delivery was made promptly to a marina on the way, the SVB crew intervened on its own initiative due to the delayed delivery from DHL - thank you very much for that! The pump fits and does what it is supposed to do - I am very satisfied with the product and the configuration.
very precisely replaces an original yanmar pump for 4 x cheaper! The dimensions with the shim washers are perfect. The pump is aligned with the motor pulley. The impeller is in the kit. The pulley is not included in the kit. Perfect
I installed the pump on my 2GM20, after Yanmar wanted to have 800.00 € for the original. The pump fits great when mounted in contrast to the original from the other side of the holder. You also need 2 hose nozzles on 13mm and I have two 45 ia angle mounted. The pump seems to be very well made, works great and the stainless steel lid promises a long life.
The product definitely fits. Only the connection kinks have to be converted from the old pump. However, I have not yet installed the pump. I use it as a carried spare part because the impeller can no longer be changed when the pump is installed.
Oh- had bad luck- after a few hours the camp was over- but hey- SVB helped unbureaucratically- sent me a new part- so that I could continue with a short break. Thank you SVB team
I have now installed 2 of these pumps. They were of the earlier type ST112, which is identical in construction except for the mount of the belt pulley. In particular, the sealing ring in the pump is the same and does not last long in the tidal area. After about 2.5 years the pumps started to leak. The Johnson pump installed by Yanmar lasted 7 years. With manual skills, you can perhaps replace the sealing ring (available from SVB) every 2 years as a precaution, thus avoiding the bearings seizing up. The life of the pump would then be limited by wear and tear on the pump housing due to running-in.
