    Russ I hope for five pounds for five minutes! If your 7.5 is an OMC motor they are a lot more tolerant to water than a Mercury. They are all brass bushings. The old Mercs call for corn head grease. They have all roller bearings and they rust quickly. Merc’s are a lot harder to seal up than an OMC. IMHO Either one needs to be checked for water occasionally and drained before freezing temps arrive.
