It has been a few years since I've seen the insides of one but I think that that hurth has separate clutch packs for forward and reverse. They are consumables.

I suspect a crappy batch of annealed 302 stainless sneaked it's way into production.

Filter was obviously made of "chinesium".

Or a foam mini roller from the dollar store.  Complete w/ it's own throw away tray.

Funny. 😊

Compressors, thinning paint worries, cleaning spray guns, masking off for overspray. 

It's  a 1" stripe.  Tape it off and paint it with a foam brush.

I limit my purchases from HF to lumps of metal with with less than two moving parts.  I like their hammers.

My Honda 2000 always starts no matter how much I ignore its maintenance.

The Universal diesel has an unusually short dipstck tube.  When the engine runs it distributes enough oil through out the engine to lower the level in the pan below the dipstick tube.  When the engine shuts down and the oil returns to the pan it can't displace the air that's trapped in the dipstick tube.

Its a 1" shaft turned by a small toy like engine. Maybe we're over thinking this.  I mean really, the whole "a keyway is not enough", "you have to lap the prop", "what's the exact torque value on each nut".  Please stop.

I'll point out the obvious that one is on a tapered shaft, the other not so much. One retained by set screws, one not so much. You figure out which is which. If you don't want to do it, YBYC, but why make a false argument against what's accepted practice?  I don't get it.

So your saying because the other end of the shaft has set screws, that makes it more robust to rotational inertia?...  and you claim to be an engineer? Please.  The set screws are for axial loads.

YBYC!   but I will pass the wisdom onto the C30 owner who, last season, lost his prop because he didn't lap it and torque it properly.  He hit some floatsom, the prop spun, sheared the key (which is what a KEY will do), spun off the nut -- and plunk, now it's a hundred feet below the surface.

I'm positive he'll get a chuckle or two!

Lap your prop or your boat will sink. 
Davey Jones's locker.  Arrrrggggg.
You heard it here. 😊

Please tell me how to deal with the engine coupling that relies on a keyway? The same exact rotational load as the prop and it cares not about laping. 
Your Cat 30 relies  on a keyway at the engine coupling. Please tell us the solution to its obvious deficiency.  The same exact rotational loads as the prop. 

Larger boats with larger engines address this issue with splines and indexing profiles.

Its foolish to read articles about large boats and large serious engines and assume we should share there concerns.

You can use any Sharpie marker as a wear indicator.

Look at mainesail's website - he shows how to lap a prop.
YBYC but you should use the lapping process.  It IS NOT the keyway you depend on, it's the precise fit between shaft ad prop hub.

kk

On my 34 the opposite end of the shaft at the trans coupling relies almost entirely on the keyway to deal with the radial loads.  The set screws there are for axial loads.  The shaft twist some to dampen the shock load but they pretty much mirror the forces at the prop.

Bigger shafts and props have larger stresses But... anyway,  proper practice is to lap the prop.   8) 8)

I installed zirc fittings on the upper and lower tubes when I bought the boat.  Everything good after 29yrs.  I don't think it will help on ones that are already Oblong.
