Highly recommend the factory service manual. There's some fine points that might get missed here.

Having a problem with the starter?

Starter: the air silencer has to come off for access to one of the 3 bolts holding it in place.

Lower unit:
1. disconnect shift linkage under the bottom carb.
2. remove the trim tab (scribe a mark across the edge so you can get it back like it was).
3. remove the retaining bolt up in the trim tab cavity.
4. remove the other retaining bolt from the bottom side of the antiventilation plate.
5. remove the four retaining bolts from the perimeter, just above the antiventilation plate.
6. pull the lower unit off.

The shift rod height is adjusted by screwing it in or out, so don't twist it or else it won't fit when you put it back.

On reassembly:
* put molly lube on the drive shaft splines.
* the rubber o-ring just below the drive shaft splines -- you need that.
* put omc gasket sealant (or some kind of anti-sieze) on the retaining bolts -- or else corrosion will set in & it'll be a ***** next time.
* use 3m #847 or permatex #2 on the joint between midsection & lower unit. permatex is way harder to clean off there next time around.
