I found water in my gear case, It is not coming out of the lower gear case where the prop shaft is nor is water getting in around the vent plugs (new seals) I replaced the oil in the gearcase and noticed new oil leaking out of the water intake where the screen is. Could the tube that feeds the water to the impeller housing be cracked? if so, can it be fixed? I also found mixed oil and water above the impeller housing so the oil water mix must be leaking into that area. And to top it all off, The shaft that connects to the power head has a spline that will not come off so I cannot replace the impeller. Any help and I will be forever grateful.
