Disagree with most of this. You can't just fix the sc if you have a ceramic washer failure. If you keep running it, the engine will self destruct. Actually, on a single engine ski or boat, the rpms will be down to around 5500 but can be significantly higher on a dual engine boat and only be off 1500 rpms for the majority of the throttle range.
If you read it, I said it could be 1.5 although that's not my experience. So I gave Creedance to the possibility. Secondly this OP said he's been running it like this for a year or two. He's getting a failure code. So to me a failure code and engine failure are two different things. So I already addressed the fact that a bad SC can hurt and engine but it would surely happen well before two years.
Maybe you would do that since you're suggesting it. But no I wouldn't keep running a bad SC. I would change the SC and look for any missing pieces. In case you didn't know you could pull the engine drop the oil pan and PTO cover. Look at the SC and see what pieces you're looking for and fish for them. If it's a single washer, I'll find both pieces and inspect the gears for damage. 4-5k for an inspection, SC new oil etc. Some people know more about repairs than others. Their shop seems to not want to use any expertise and just replace the engine.
Both pieces, lol. Yet to see a ceramic washer break in 2 pieces in the 100+ I've done. That's not how they break.
Yet you're the same guy that would change a Motor over looking for washer pieces [emoji23]. And you've worked on 100 and Changed 100 motors [emoji1787] [emoji1782]. As I said just change the SC. Save your self back away slowly. 100+[emoji1782]
I responded to the OP not him. He responded to my post. So I give my reasons and I'm defensive? Yeah Ok. He could have a million posts that means no one else know anything, com'on man that's irrelevant. Many ppl work on engines but don't live on the fourm. I offered my advice. And it still stands. Oil consumption can be an indicator of damage but should be carte blanche for a new engine, prime example would be the invent of catch cans. Oil consumption can have a few causes. We don't know what the cause of consumption is. If the OPs mechanic wants to install a new engine the mechanic should have said hey your compression is bad, you have damaged gears internally. checking compression is the way to determine that as I suggested. And a code is also not a good reason to change an engine without further investigation. If compression is fine, Take the engine out inspect the gears find the pieces. A little due diligence goes a long way. If anyone feels that convicted, DM the OP don't dispute me especially if I'm not telling him something that's going to get him hurt or killed. No one commenting on this is getting paid or fixing the boat. Just simple advice so yeah it is off the rails.
