Drive Shaft Pits and h20 in gear oil???

[hallhen]

I have pits in the drive shaft close to the water pump seals. I beleive this is allowing water in the oil and there is oil on the pump. <br /><br />Is there anyway to repair the pits without replacing the drive shaft?

Might be able to find a machinest that can do a wrap on it and then resurface it. I am considering having this done this winter. A guy here is figuring about 80 bucks to do the job. Looks like a new drive shaft assembly for your motor is around $400. Might want to call around to see if anyone will resurface yours

Have you heard of a process called "metal spray"?<br />Found an example on the web at http://www.metaltech.ca/Shaft-Repair.htm. <br />and http://www.corrosion.com/thermal-sec5.html <br /><br />A local marine shop parts guy is suggesting I try this process.<br /><br />I would like to here your opion.

I used to do lots of metal spray jobs for local boat shops here in AZ. Closed my shop 5 years ago. I am building a new shop and will start doing metal spray again soon (summer 2004). Jobs on shafts like yours would be around $85 plus shipping. <br /><br />AJ
