Hi... I am replacing my prop shaft (1.24" normal taper, 58" long for yanmar
27 hp diesel) for my sailboat. There is a grease fitting in the stern tube and grease was pumped into the stern tube as a means of keeping water
out. With the new shaft, new stuffing box and flax I want to get the grease out and not use grease as it eventually works its way out and makes a helluva mess. Most of the grease I have pushed out with a broom handle and cloth. Is there any solvent that will dissolve the grease if I fill the stern tube with it and let it sit overnight then drain it out?
Also, I noticed at the exit of the shaft on top and bottom of the stern tube there are 2 screws (one each). I am assuming these are to hold in the cutlas bearing and are not there to be tightened down onto the shaft?
Lastly, there are 2 nuts to thread on to keep the prop on. One is thinner than the other. Which one goes on first?
