First...thanks for all your help so far...its amazing the wealth of information on these boards...OK I posted earlier about gear case lube leaking ...thought it was the prop shaft bearing seal...but after further examination I believe it is farther back in the bearing carrier...my question...I think it might be the o ring around carrier..does anyone have any experience...or is there a fairly common cause..ie o ring gasket failure which is common to this gear case..I am going to order the complete gearcase seal kit...should this fix the problem barring any cracks in the metal itself...any input welcome...thanks...Peter
