Hi,
The weather was finally nice enough here to get the boat out for a test run since the pump overhaul.
FYI- I replaced:
-floating ring (plus O-rings)
-carbon ring
-impeller (Solas 14/22) plus boot
-wear ring
-neoprene seal
-pump shaft seal
-pump oil
I also resealed the ride shoe, realigned the engine, rebuilt the carbs and readjusted all the linkage.
The boat ran awesome - like a whole new boat! Jumps right out of the water and hit a top end of 53 on the speedo.
Previously the hole shot was very weak, and it topped out at 45 (speedo). So many thanks to all who helped!
I do have 1 concern however...
I noticed while idling back to the dock that I am getting quite a bit of noise from the back of the boat. Kind of a rattling/almost grinding kind of noise. It does disappear with throttle and is not noticable while driving at speeds above idle Would this be normal because of tight clearance on the pump impeller and wear ring (.010") and natural engine vibration? Or could this be a bearing issue? I did not replace the bearings, but I did inspect and clean them.
Any ideas/insight is appreciated.
