Rattle in Mastercraft 88 prostar 190
So over the summer we have heard a rattle coming from the transmission and pulled the transmission to investigate. The sound was like rocks were clunking around in the tranny. We had a mechanic pull it apart in july and he found no big issue. he replaced our damper plate abearing or two and the transmission oil pump gear assembly. The day we got our boat back the rattle began again. Its seems to be at a low idle when in foward and reverse and goes away over 1000rpm. We ran the boat till late october just ignoring the sound and on our last cold day we thought we blew up our transmission with huge clunks and the engine wouldnt pull a skiier out of the whole. We putted our way back to shore and put the boat away for winter. Now we have our transmission apart on a bench and find nothing wrong??
Could this be an engine related issue? All fluid levels are good. No water in transmission, Propeller on tight.
These are other tiny facters that could be related
-Oil gauge fluctuates rapidly/
-Thier was sludge in our bell housing when we pulled tranny
-Five times this summer the engine had trouble warm starting(flooded carb?)
-Metal shavings on transmission magnet
