Impeller change for dummies

Hi,

Can anyone explain to me or have an electronic service manual they can email for changing an impeller on a Tohatsu long shaft.

I know there is 4 bolts to remove on the lower leg but what else needs to be undone. Assume something on the gear selector?

Hi Matt,

Thanks for reply have removed trim tab, but still isn't coming off. Is there nothing else such as on the gear selector that needs to be undone.

So far I have removed the four lower leg bolts, trim tab as suggested and it's not budging

Theres the four bolts, and then a connector on the gear shift rod, it has a small pin that needs pushing out.

See no. 21 on image.

Sometimes the driveshaft spline can get stuck into the crankshaft, don't apply too much force on the cavitation plate as it will break easily. Remember to grease the driveshaft splines before reassembley.

So next question does this just need a new impeller or full kit?

I have no history of this engine and it doesn't seem to have had much tlc, also there is a snapped earth wire which from looking at some of the softer metals has been broken for a while.

On pulling off the lower leg it was full to the brim with grit.
