Looking to replace my Kohler Courage SV690 as she's worn herself out. Seems to be a common issue.Looking to be pointed in the right direction on best route to replace. Anyone have any knowledge as to a direct swap? What series briggs has the closest output shaft length, diameter? and can I use the same pulleys? Any info is greatly appreciated! thank you !

You sure it's a 690? Not a SV590?
If it is a 590, the new engine will need a 1"x 3 5/32" shaft, look up small engine warehouse repower page, or repower specialists .com

I was told 690, could be a 590. Its my 78 year old fathers, and I'm just trying to keep her going. what are the major spec changes between the two?

Well, as far as i know Kohler didn't make an SV690... THEY DID how ever make an SV600 and a sv590, Do you know the Horsepower rating?
And, depending on the issue, we might can walk you through on how to fix it. These courage engines had *Several* common problems.

I'd like to take the engine off and put a somewhat more reliable power plant on the thing. I was curious if there was a Briggs, or other brand compatible with doing so. and what type of mower i should be searching for to take one off.

take a look at this one, you might shop around for the same engine on ebay or amazon etc.. or see if anyone on your local craigslist has a tractor they want gone with a good engine

If spending money on an engine, should I replace the blown motor with the same Kohler Courage or replace it with a Briggs? I haven't heard great things about the Kohlers.

It was mostly the early model Kohler courage's that had that issue... I believe they (Factory in china, i think) fixed the issues of the top crankcase cover bolts coming loose, i know another member on here ( @bertsmobile1 ) knows more on that subject than i do...
Another thing is that 33r877 briggs had issues with the camshafts (cam part 793880 changed to new 84005207)
failing due to poor hardening of the lobes, then again I'm not sure if the issue was resolved on newer engines, but i do know they upgraded the replacement camshaft in it and is available for purchase.

I have the Kohler courage 19 sv590 on my cub cadet, It's been bullet proof except for the carburetor needle failing, (Which in a way is a Carb manufacturer issue, not kohler, that's my opinion) it has 300 hours on it.
but really, any of the problems with the courage can be spotted and resolved, since i don't mow enough hours each year for the recommended oil change interval, i do it at the start of the spring season, when i do that, i remove the plastic cover and check all the crankcase cover bolts to be sure they're tight, i also remove the cover in the middle of the season to blow out the cooling fins, i check them then too.. takes 3 minutes. i also check for any signs of the valve cover leaking, takes 2 minutes ( i always clean any dirt and dust off around the cover so any leak could be spotted easier). That can be done while the engine oil is draining instead of twiddling your thumbs.

my 2 cents, if you want to wait on someone else's opinion you are more than welcome too, as there are smarter people on here than me.

That is a good choice I just change one out. there will be some wiring changes at the engine connector needed and the muffler 0ff the Kohler will not work to exhaust out the front . The muffler needs to come out the front so as not to melt the hood if it is a plastic hood

I see now it has a muffler kit with it good price also

I have a SV590 18 hp Courage with over 800 hours on it, if you take care of them you can get good service out of one, all I've done is adjust valves every couple years and checked torque on pan bolts every year, I'm quite sure I'll get well over 1000 hours out of it.
