The extra salt may mean a new exhaust manifold sooner...five years, maybe? But, it
appeas very easy to replace on that four. And it looks like they run less than $400.
On the V8, they were a bitch, and much more expensive, of course."

A new exhaust manifold every five years doesn't
appeal to me. You'd think they would come up with a better material.
I've never owned an inboard/outboard and I am a bit leary about it. I'd
better start reading up on how the engine cooling system works and how
much routine maintenance is required.
Already I can see that the optional 23" deep swim platform is going to
make flushing the lower end a bit harder. The idea is that platform will
make it easier for the dog to reboard after swimming. The 170BR with
outboard motor has a very narrow reboarding spot next to the outboard well.

Well, you'd best adapt to the extra difficulty, 'cause you'll want to flush it every
time you use it. Do they have a hose connection on them now, or will you have to get
a set of muffs? If muffs, don't skimp. Get good ones that fit snugly. My I/O boat was
11 years old when I traded it in, and I'd put new manifolds on it at about the 9-10
year mark, not seven as I'd said earlier. I did have mine magnaflux tested about the
7 year mark. That was worthwhile, but luckily I had a son-in-law who had it done for
me - free.

My manifolds are freshwater cooled. Elbows will be the only thing needing
replacing. I have closed cooling, with heat exchanger.

Closed system is actually the best way to go. a friend of mine loves to boat about year around that is when he can, and installed a heater core in the cuddy so he can duck inside and get warmed up.

Plus, the automotive style engine can warm up to a toasty 180 degrees and run more effeciantly than thee usual 130 degree raw water system.
