Silver Century Plus noise when in gear
Posted: Sat May 12, 2012 10:18 pm
I have a '68 or '69 Silver Century Plus longshaft. I haven't run it in a few years.
I put in a 25:1 jet and when I went to tank test it it fired right up and was running fine. However, when I put it in gear I am getting a loud whirring that doesn't sound right and I don't think it was doing it last time I ran it.
I drained the lower end and I had the thick tan sludge of 140 weight emulsion that has been in there. I took the lower unit cover off to clean it all out. The gears look a little corroded but I have never had it open before so I don't know if that is how they have always been.
With the plug removed and the main gear out when I spin the flywheel I don't hear any sort of rubbing in the driveshaft.
Any thoughts on things to check. I can post pictures of the gears if that helps.
Thanks,
Shawn
