hi all just curious of a small gear case leak on my 1978 115 hp johnson serial 115 etz 78c 632032.its only a small leak but would this require new gear case seals?if so what part numbers am i looking at ?im going to drop the oil and see if any water has worked its way in which i doubt.the other question is if its not taking on water could i just keep topping it up untill our so called australian summer ends and then give it a seal change if needed?thanks for the advice
