Does it hurt for the prop to spin when towing?

Only if it hits you.😁

It would be better if it didn't.  Just throw the control box in Fwd. Gear.

Might overheat unless air cooled motor...

Just like running it.  Adds hours.

The only thing turning is the propshaft.....but still, if I was going more than 5-10 miles I would rather it not spin the whole way.

I might be totally wrong but i believe the engine has to be on to add hours.  I was also told by a Mercury Master Tech, to never let my Merc idle while i go and put my truck and trailer up off the launch ramp, as it will add hours like crazy.  Say you launch and visit for a minute or two by the time your ready to roll that is probably going to be 10 minutes of idle time added to your meter.

Everyone wants to steal a used boat by claiming the number of hours effect the price.  For every 5 or 6 times you launch you put an additional hour on the meter you are killing yourself and that motor does not need to warm up 10 minutes.

Mercury says their old big block 2 strokes should easy go 1,500 hours and their new 4 strokes should handle 6000 hours no problem. if both are maintained correctly. Yamaha is saying 15,000 hrs. on their big block 4's is not unexpected.  Yet boat buyers throw a fit if you have 300 hrs. on a 5 yr. old boat.  Just Ridiculas.

Pretty much why we are seeing 8 yrs. of warranty, as the motor companies know we are not going to use that many hours and they are built to do way better than their time of warranty

Malarkey!  I love their disclaimer.  

"Hmm, it gave up the ghost at 450 hours?   ....Must not have been maintained correctly".    😅

It couldn't possibly be that it wasn't BUILT correctly.

I know the majority of us are more familiar with outboards over inboards. But my wife has decided she wants a nice deck boat for us and family gatherings. But I could not tell you the first thing about an inboard motor or it's maintenance requirements. At least with an outboard I can tell you what color it is.  

So my question is. All things being equal in proper care and treatment. At what point do you start thinking " I don't know, that's a lot of hours"? What would you folks with knowledge of them feel comfortable with? And yes, I will be keeping my little tin boat. My wife will captain this barge. Thanks, Mike

Not related to the inboard question, but as far as outboards, I don’t let hours bother me on a used boat. I’ve seen just as many brand new motors getting powerheads as I have old ones.
 

I’m looking for a well kept package by an owner who used it a lot. In my humble opinion, running a boat enough that the gas stays fresh, as well as letting it warm up enough before you go WOT, are the two things that make a motor last the longest.

no matter how creampuff, a boat that is used one weekend a year is gonna have issues, in my opinion.
