Re: pre-alpha gimbal interchange
I'm new to the boating world, so I appoligize for the incorrect terminology.
So let me ask this; So a MC-1 gimbal from 140 will work for my 160 mercruiser engine. what
upper stern drive ( I hope I got that term correct ) would fuction on that gimbal? And
what lower gear case ( not sure if thats what its called ) would interchange?
Mark
The gimbal housings for your 160 is the same as a gimbal housing from a 140 to around 1983. (The rear engine mounting point were moved closer together for the later ones.)
Upper housing is called Drive shaft housing and lower is called Gear housing.
All the uppers, lowers and gimbal housings are completely interchangeable up to year 1990. That is the complete housings, not internals. So onto your MC-1 gimbal housing you could have an Alpha One drive shaft housing and an R gear housing bolted to that.... or an R drive shaft housing on an MR gear housing... Just make sure the ratio (determined by the tooth count in the drive shaft housing) is correct for your application. Your 160 should have an overall ratio of 1.68:1. As that's no longer available you can use a 1.65:1 ratio, as far as your engine's concerned, no difference....
So, to answer your original questions....
.... will this gimbal assembly for for my boat, and will my stern drive assembly bolt up and work???
Yes, and yes.....
If you ever need to replace the drive, consider an SEI drive. Complete assembly for ~$1300, separate housings also very cheap....
