Thanks you, first off for your help! You are correct about my shaft number is 329257.But I have counted the splines again and keep coming up with 19 on the lower unit end and 14 on the power head end.But I now have a part number to start hunting for. I got this motor at a good price and it looks like it was hardly ever used. But its a long shaft!.I have been to 2 local outboard shops in my area with no luck for a match. One had the same shaft just not a short with the spline count.If I can't fine a shaft, my son works at a machine shop and I will get him to shorten it.
But I would really like a replacement short shaft instead if I can fine one at the right price. I have time to look with winter and hard water here.
Thanks again,and Happy Holidays Would you please check that spline count one more time. I can't find a single driveshaft with a 19 spline count.
1988 28SPL driveshaft(20")part number: 0329257
1984 was the last year to use the "old style" gearcases on recreational 25hp engines. These gearcases were used on Commercial engines all the way up through 1997. They were also used on the 28SPL engines. If you look up both driveshafts for Commercial engines you get part numbers as follows:
0329237
DRIVESHAFT, Standard
0329257
DRIVESHAFT, Long (This should be yours)
These part numbers supercede upto 1996-97 model years for similar commercial engines:
0341649
DRIVESHAFT, Long
0341650
DRIVESHAFT, Standard
Your driveshaft should have a number on it. (0329257)
Please let us know what you find.[/quote]
