The bravo drive came out after Volvo’s patent expired, OMC followed suit.

The VPDP comes out, then the Bravo 3, Volvo comes out with IPS, Merc comes out with Zues, VP forward drive comes out
then the Bravo 4….not a lot of imagination up in Fon Du Lac in the stern drive department

The Black Hawk was
the exception, but they killed that off in only 2 years

Will let my stuff go cheap, my mum live in Victoria and if your not in a rush I could drop off anything you need, I have tons of trs stuff as I am switching my 1977 30ft scarab over to Volvo penta dp drives. Let me know if you need anything, it’s turning into yard art.

I'm looking for TRS lower units for my '87 BAJA FORCE 320.

I just sold one of the trs to tartilla, what prop rotation do you need, as I can’t remember which one he took, also I never used these so I do not know the condition of them. Let me know what rotation you need, also I am away for work all week and will not be home till Saturday or Sunday

I will check when home, I do not want to separate upper and lower, this drive is 48 years old, I am very leery of selling them as I don’t know the condition of the internals. You maybe better off trying to find a lower that’s in good shape, versus shipping one of these giant beasts of unknown condition

Your right, all I really need is the lower case.
