i wouldn't like to imagine the bill for those bits IF you can even find them new.

i would think getting a used lower unit is going to be the only way to proceed. i'd do some research on what gearcases will fit on that engine and get some wanted adds up. i.e 50-75hp lower units maybe the same? guessing on that but you get idea.

cheers

Try IMS (International Marine Supplies) - they keep loads of old Soozook parts.

300 sounds cheap. I rebuilt a DT85 lower unit in 1995 and it cost over 500 for parts then.

If you haven't rebuilt a lower unit before with new gears, then I'd recommend you get a good service manual (preferably a factory one), as it isn't simply a matter of replacing old with new.

Your Soozook dealer should be able to supply you with a manual.

The gearset needs to be shimmed to ensure the forward, reverse and pinion gears mesh correctly. You may be lucky with the shims from your old gears, but this is unlikely, in which case, you'll need a set of different thickness shims to go with the new gearset. Choosing the correct thickness is a case of trial & error, using 'engineers blue' to check where the gears mesh with each other, then stripping down & rebuilding with different thickness shims until you get it right. Soozook dealers will have a box of different thickness shims to choose from, but as you're doing the job as a 'one-off', it probably isn't worth your while buying a whole set. Probably worth getting a quote from a dealer/specialist for the rebuild, as it isn't a job to be taken lightly.

thank you for the explanation, this helps.
specialists are all booked these days and i only have an older gentlemen builder trying his best.
the engeneers blue will help and then i hope it all works.
will we need all 3 sets of shims? so# 8,13,23?

You'll need a range of different thickness shims for each of the 3 gears to be certain of getting it right. Sometimes the fwd & rev gears use the same shims - can't remember if this is the case with the DT65. You may get lucky and be able to recycle some of the ones you have, but don't rely on this.

great, thank you for this!
will a service manual do any difference?
tried downloading from the web but it seems they are all fake / costly.

The SELOC manual is pretty good at describing the procedure.
