please teach me on drives
What are the difference between speed master 3, 4, 5, and 6. I have TRS. Does speed master have the same upper a TRS has and just the bottom is different ? Thanks.

No there not.
3s 4s 5s all have two sets of gears in the lowers & two vertical shafts. 3s&4s came with either small or large prop shaft. ( 19 spline or 26spline) The 3s were used on mostly V hull design because of there longer X height,4s were mostly used on cats at the surface with a larger prop shaft & shorter X dimension.5s are are much like 4s but with larger bearings and shafts.There Gimbel will also support more HP. Same with 6s but the big advantage is that steering is built in the gimbel assembly.Parts for 3s& 4s are getting hard to come by.I'm not totally sure but I think production of the 5s will also be coming to and end. All great drives in there time. |

SSM 3A's and 5's are the same drive with the only difference being drive height. The SSM3A's are longer. They are both still production drives that you can buy new and have no issues getting parts for.
SSM 3's and 4's are no longer in production. The way to differentiate between a SSM 3 and SSM 3A externally is the 3 has a 19 spline prop shaft while the 3A has a 26 spline propshaft. Internally the 3A's have larger bearings and gears than a 3. A good source for SSM info: http://www.mercurymarine.com/drives4 |

shaft. Buy a set COD off classified section and see if the UPS driver will hang around long enough to look at internals. |
