Help! 280/290 Duoprop stern drive

[Slobbit]

Does anyone know where I could pick up a good second hand or recon Duoprop lower gear box which would make the overall reduction 2.30:1.
To buy one from volvo at their grossly inflated prices is not an option, but if someone knows where I could pick one up at reasonable cost I would be very grateful to hear from you.

Some idiot has fitted a 1.95:1 on the port side and a 2.30:1 on the starboard side, great if you want to go round in circles!!

Two places to look Boats and Outboards website and Coastal Rides.

I'm sure there will be quite a few more answers coming soon.

Coastal rides will probably do you an exchange deal.

Ivss are good and know there stuff

 

[Slobbit]

Thanks but already tried IVSS they don't have the gear ratio I need

Coastal rides is a possibility but I'll have to get the box off quick sharp as they only have one with the correct ratio.
I can't believe how rare these are there must have been thousands made!

Just out of interest, what engines have you got ?
There were 3 std ratios available,thought the highest one was for diesel and other two for petrol.

Hi,
For the duoprop leg they only made two ratio's 1.95:1 for the petrol and 2.30:1 for the diesel.
I have two AQAD30 diesel engines so the one I want is 2.30:1, the leg fitted with the 1.95:1 is holding the rpm on that engine down to 2000rpm max it needs to get to at least 2500 before the turbo will make any difference.
