letsgocrabbing Posted January 17, 2016 Share Posted January 17, 2016 Just wondering if any owners have had issues with oil leaks. Ours is a 175hp and is leaving a visible trail on water surface and losing a litre of oil every trip. No problem with compression and oil leak not visible anywhere when main engine cover cowling removed. Oil appears to becoming out through the bottom joint at the rear of the secondary under main engine cowling. Any thoughts ( oil sump seal/rear main/oil pump seal).

Shiremm Posted January 17, 2016 Share Posted January 17, 2016 It's common on those motors to have an oil leak from the bottom main seal. Please include any pictures you have. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Shiremm Posted January 17, 2016 Share Posted January 17, 2016 How many hours are on the outboard? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
letsgocrabbing Posted January 18, 2016 Author Share Posted January 18, 2016 4000hrs. The boffin we spoke to at Honda naturally said " seal' failure unheard of when we first were chasing clues as to what could be responsible. If bottom seal do you have a rough estimate of repair cost?
