wonder if this owner claims to have "always flushed"

[fairdeal]

saw a post on another site, someone selling "the midsection"
of a 2002 F225 -
said the powerhead failed due to "metal fatigue" at 750 hours

I was impressed by the "calcification" in the exhaust guide:



in contrast,
this was my F225 looked like when I pulled the powerhead off at 1000 hours

No need to rinse her out...drive her till she blows up...lol

I keep my boat across the creek from a big Boatel. There are probably several hundred boats in there, maybe 20-30 percent of them powered with Yamaha outboards, perhaps more. They pull up to the slip, they get out, grab their shit and the forklift is right there. Pretty sure most of them never get rinsed.

My issue is that I don't have fresh water available for flushing in the winter months. The owner shuts off the well pump to protect the lines from freezing. As a result, I have no idea what my 300-hour engines look like internally. But, I'm not going to pull them apart to find out and I don't run the boat that much in winter. Hopefully, that is minimizing the issue.

Sucks, but it is what it is and I don't lose sleep over it. I'd rather rinse, but it's not always an option. Engine manufacturers ought to strive to design their engines to withstand this type of abuse. Think of all the crummy little spots around the world where no means to rinse is the norm.

Pics of the latest girlfriend???

It was flushed... With salt water...

BTW, the one marina I had to leave the boat at (years ago) for a fix/part (forgot), they put muffs of every boat, mine included(as I saw it) and ran it on fresh water for maybe 15 minutes, idling. Guess it depends on the Marina and their procedures.

Mako, if you have an on-board fresh water tank and pump, you can easily (once done boating), hook that up to the flush port and get at least SOME FRESH water in the block. Better than nothing..

hard to do that if it is below freezing,
even the onboard water tank will freeze solid if he has fresh water in it.

I would hate to have to deal with boating in freezing weather

+1 ^^. My boat would be parked and winterized...

Hard to flush when the garden hose is froze solid..lol

Haven't had a FROZEN garden hose since 1979... Don't miss it either!!

[rodbolt17]

how can you flush an area that has NO water to it?
that pic????? all dry baby no water can flush it.

try again.

IMG_0183.JPG As 99yam40 alluded to, I don't keep fresh water in the boat during the winter months out of fear of it freezing solid and cracking my fresh-water tank. That tank was sealed in forever when the cap was bonded to the hull. There is no way to repair or replace it. And even if the temp did stay at 33 degrees all winter, I doubt that an electric pump would provide enough PSI to do much for the engines cooling passages.
As I mentioned in an earlier thread, while more fresh water PSI is probably more beneficial than less PSI, I think the presence of fresh water and time that it's circulating through the engine is more important. I'm not trying to blow silt and crud out of the engine, I am trying to dissolve salt crystals.

It's less than ideal but it is what it is. I'll likely fish again this winter, and if the humpbacks show up again, I'll be out there with them as well.

Mahi 35 miles off the beach this week. Took home 4 nice fish. Let the peanuts go. Sadly, two of the larger fish were gravid females. Engines ran great all day. Imagine that!

No evidence of caught fish in that picture..lol Glad your engines are running good.

what is all of that floating on top of the water in the pic?

Oh boy, an "issue".....
