Yamaha 60hp

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.

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.

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.
