Question

[reefshark]

My mechanic installed spacer shims on the bolts that connects my lower unit to the mid section that creates a gap between the lower unit and my mid-section. The mechanic claims the OB manufacturers found that by doing this the motors run better.

Any one have any experience or anything to add to this?


Thanks

I have never done that, not sure if it's true or not.
