Well the Sara Belle is finally winterized. It's always a sad time of year because I won't see her for another 6-8 months.

While changing the outdrive fluid I got the dreaded streak or milky discoloration of the previous fluid. It wasn't much but definitely noticeable. While changing the fluid, I did notice the lower screw for removing the fluid wasn't tight. I must not have used the impact screw driver properly the season before to crush the gasket. I'm hoping that's the case.

Does anyone have any other ideas what to look for? I don't see oil leaking from the drive. Putting about 30-50 hours on it this season, my fluid reservoir moved to the refill level, which is typical after the season.

Any tips would be appreciated.

Thanks
Ollie


edit: I guess this should have been in the "maintenance" section of CSR. My apologies.

Pressure test it. Using an impact screwdriver on that small screw is asking for trouble.
 
I used the wrong description. It's not a Milwaukee lithium impact driver. It's the driver that you hit with a hammer to loosen and tighten the screw and crush gasket at the drain/fill location. Actually both locations
 
Same diff. would not hit that with a hammer. Try those newer merc ones that are yellow and soft not the old style cardboard type.
 
Yes - there is no need to use an impact screw driver - just good and snug with a large screwdriver - or a screwdriver bit on a socket wrench. Do not overtighten.

You can pressure and vacuum test.
