I have a 1994 larson 280 with twin 4.3LX alpha drive Mercruisers, which have about 410 hours on them. I just had the impellers replaced, as the starboard engine was overheating at high PRM's. Prior to the repair, the gear lube reservoir would drop only slightly during the season (it was being used on a slow speed-limit river then 
)<br /><br />However, during the past month I have taken it across Lake Ontario & around in the St Lawrence but just noticed that the gear lube reservoirs have dropped almost to empty .<br /><br />Is it likely that there is a connection between the impeller repair & the change ? Did they likely botch something?<br /><br />My guess is I need new seals when it is pulled for the season. Previously, when having the gear lube changed, it has been reported that all looked fine. Should I be worried at this point ?
