Re: Trim fluid?? Force 125
for oildyne match existing fluid. Factory default was ATF.
If existing fluid is red then use Automatic Transmission Fluid. If existing fluid is honey then use ISO32 hydraulic oil or sterndrive power trim fluid (from marine dealer).
Unless you clean and flush both pumps and rams then you need to match existing fluid. ATF and oil do not mix properly. If system has been cleaned and flushed then ISO32 is best.
