RWC Engines in Saltwater
I know the instant response is that they Probably have problems, but can they be taken apart to some degree to know for sure? Thanks for any input!

Re: RWC Engines in Saltwater
If you have no leaks or external corrosion at the manifolds or risers there is a good chance they have been replaced at least once. They are your "weak point" for raw water cooling systems.
If you own the boat, or are considering purchase, I would run the boat to temp and take several temp readings with an infrared thermometer on various areas of the block and manifolds. If these are fairly close, left to right, front to back, I would then get it out on the water at cruising speed and do the same again after cruising at speed for several minutes, assuming it is running within normal operating temps.
Any hot spots will give you an indication of possible scale build up or corrosion. Not a perfect plan, but should give you an idea of the coolant flow and possible problems needing further investigation.

Not sure what you mean when you say , can they be taken apart to some degree, well you sure can, but really why....like has been said a good hard run for a while watching the temps will tell you.....if the cooling system is having problems it will for sure show up after 15 to 30 minutes at cruise under load.
There are some engine flushes that have been talked about lately that may help....do a search on the forum.
