OK, well that carb body has had in, no good, no way to save it…Finding another carb should be easy and not expensive.
Like I said, I don’t recommend using those aftermarket impellers, but that is up to you…
Looks like you pulled off the intake manifold, so you may want to pull the reeds off to inspect and have a look at the crank/rods, then replace the intake gaskets..Don’t mix them up, the inner gasket is different from the outer gasket…Install the gaskets dry, no sealer of any kind.
These engines don’t have alot of compression, do you remember what the readings were? Somewhere between 70-85PSI is normal for these engines. I can’t tell much about the cylinder condition from your pictures, but you may want to soak the cylinders with engine tuner just in case the rings are a little stuck. Again, I do not recommend pulling this powerhead apart unless you find evidence of damage on the cylinder walls such as aluminum scuffing on the walls or deep scores. I would use a little fine emery to clean up the glaze on the walls, this will help the rings seal. Yes, this is a primitive procedure, but we are not working on an aircraft or rocket engine here. Rough up the walls a bit, then clean out the residue with carb cleaner and recoat the cylinders with two stroke oil. Doing this might help get a better look at cylinder condition also.
You will need a new head gasket, you will want to check the surfaces to ensure they are flat, you may have to resurface the cylinder head mating surfaces if it is warped. You will want to clean out with block threads with a tap, and the bolts with a wire wheel before reinstalling the head. Coat both sides of the new head gasket and head bolt threads with OMC gasket sealer. The powerhead does not appear to have been overheated by the look of the paint.
Just because nothing is leaking out of the gearcase does not mean it doesn’t have a leak…Remove both of those large fill/drain screws from the gearcase and let it drain into a clean pan. Look for signs of water and report back…You will need to remove that powerhead from the exhaust housing in order to remove the gearcase and service the water pump. The shift linkage connects directly underneath the powerhead.
Take some time to review your manual’s procedures for the work you intend to do…Get back to us when you have more questions…
PS- Your pictures show the gear shift in the reverse position…The tilt lock is engaged in reverse so you won’t be able to tilt it up…Try shifting into forward gear, perhaps that is all that is preventing you from being able to tilt the engine up…
