lower unit winterization

[jerkin]

Is it ok to just drain the lower unit for winter and fill it up in the spring, or do you need to keep it full?<br /> Thanks, Scott

Re: lower unit winterization

keep it full, also check the area where the bearing carrier meets the case at the retainer for corrosion, to much and it can crack the case.<br /> most carriers need to be removed periodically if run in saltwater or case cracking is assured.<br />may take 5 or 7 years but most crack eventually. freshwater boaters dont have that issue.<br /> but with no oil the moisture in the air will allow the shiny parts to rust.
