Force 50HP Carb Notes: 1985, a 1987, and a 91-92

[777funk]

I figured that ALL Force 50HP Carbs interchanged through the years. But these two are quite a bit different. The throat is a bigger diameter. The flange is much wider between bolt mounting centers. Even the bolt holes are bigger.

My 1987 Force's carb part number is:
WE17A - (Walbro I believe)

This one off of ebay is:
TC-102A-944 - (Tillotson I believe)
I looked up the number thinking it wasn't even for a Force 50 and sure enough. TC-102A says on this chart that the application is for a 91-92 Force 50HP.

I also have my dad's 1985 carb here for cleaning. It's very similar to my 87 in dimensions and will mount up on my motor. I notice that the 1985 carb choke lever sticks out about 3/8" further. His is made by Tillotson. His part number is marked on the carb as:
WB7B

So just incase anyone wonders... some data points on the carburetors for Force 50HP outboards. You can't use a 91-92 carb with the earlier engines (at least without some other changes).

In 87 Force was part of US Marine, by the 90s I believe it was part of Brunswick, which also owned Mercury.

As jimmbo says, Brunswick (Mercury) bought Bayliner and they sold package boat, engine and trailer.
The boat where equipped with Force engines and Brunswick got the Force engines in the bought.
I think that was in late 80.e, in 1992-93 Brunswick started to put Mercury ignitions and lower units to the Force engines.
In 1999 Brunswick stop build Force engines, the regulation of the emissons increased and they decided to discontinue Force.
