Hello everyone. Hope you could help me with a prop shaft problem. I am fitting a new prop shaft to a model tug. Got one made up by a well known model boat factory and all seemed well, it came with the stuffing tube, shaft and oiler as requested. It spun freely and i duly fitted it ( resined it into the hull ) and when dry i tried to align the motor to it. I then found out that at the oiler end the shaft is a nice fit in the bearing bur at the prop end you can ever so slightly move the shaft in a up and down motion as if the bearing at that end is to big ( or the shaft too small ) Should you have any play at all in the bearings or should the fit be ' snug ' ? I have rang up the factory in question and they say to send the hull back for them to check, i am mentioning no names to give them the benefit of the doubt so what should i do, run it as is and hope for the best or send it back? The model is only 24inch in length ( no deck or wheel house fitted as yet ) so hopefully the postage will not be high. The end of the shaft at the motor end runs below the water line so obviously i want it to be as watertight as possible. I would like you thoughts on this matter as i have learned a great deal from all the the Forum and it's witty members. Regards, Dave.
