Yamaha 60hp

TUFTY · 11 June 2010, 11:27

Hi

I need to remove the lower unit on my Yamaha 60hp 3 Cylinder 2 stroke.

I cannot see where to release the gear selector rod, does anyone know where
it is located?

Some pictures attached to help with identification.

Thanks

Paul

To drop the leg on a Yammie, ensure it's in neutral, then undo the four bolts under the anti-ventilation plate. Also undo the sacrificial zinc anode. You'll find the fifth bolt underneath - which also has to be released. If it refuses to budge after all bolts are removed - use a rubber mallet and lightly tap around the top of the plate.

if you look at where the gear shift cable is attached to the engine
you will see there is a rod that goes across the engine between the bottom carb and the engine tray.
if you go around to the other side of the engine from picture 2 and look under the bottom carb
you will see the gear shift rod coming up out of the leg attached with a pin.

OK can see the rod and pin so ready to drop!!!

All the bolts have come out ok and the unit has split ok.

Cheers

That's Suzuki. Yams have a splined gear shaft that splits at the lower unit. Once all 5 bolts are out, it should drop off. Don't try and remove the shift shaft under the carb at the top.

Cheers Nos

Will do in the morning.

Can anyone suggest a supplier who can supply a complete
lower unit service kit?

I plan to change all the shaft seals and impellor.

Thanks

If the lower unit wont drop off dont hit the anti airation plate!! it will crack off really easily!
if it does need a tap, hold a piece of 2x2 soft wood along the length of it to spread the energy and tap that.

Many 'small' (ie not THAT small) taps are better than one big bang too-the vibration is far more likely to free it than a big shock.

A good place to hit it is on the angle edge on the anti-cavitation plate or the gear box (but only with a rubber mallet). Good tip is to 'lube-up' the splined propshaft with Duckham's marine grease on removal. If you renew the impeller ever year or ever two years - then there shouldn't be a problem.

removed the lower unit this morning.

No Bashing required at all it came of very easily.

Now need to get the service kit for it, anyone reccomend a supplier ?

Thanks for all the advice (so far)

Paul

Nos4r2 · 13 June 2010, 13:05

Any Yam dealer really. I use Mike Cripps at Redline outboards in Abingdon for my parts.

That won't include the driveshaft seals though.

The parts you need should be:-
90430-08020-00 GASKET . . . . . . . . . . . . . . . . x3 (maybe only 2 needed-these are the drain screw gaskets)
93101-23070-00 OIL SEAL . . . . . . . . . . . . . . .x2
93210-46044-00 O-RING . . . . . . . . . . . . . . . . x1
688-44316-A0-00 GASKET, WATER PUMP . . . . . x1
6H3-44324-A0-00 GASKET, CARTRIDGE . . . . . . .x1
6H3-44352-00-00 IMPELLER . . . . . . . . . . . . . . x1

I've taken those numbers from a '96 model 60. They should be the same as yours, but double check!

TUFTY · 14 June 2010, 16:43

Cheers for your assistance with the part numbers

I have just spotted a seal set on Ebay item no 190403750408

Do you think this includes the correct set?

I would still need an impellor.

Thanks

Don't think you need all that.....

Driveshaft seals (2 of them) are underneath quite a bit. The bottom 3 gaskets in the list are the pump housing gaskets as the ally block under the waterpump will have to come off.

Looks like that might be the right gasket set, but ring and check.

Makes sense to change the impeller while it's apart.
