I had a pair of 575's in my fountain and they were a great pair of motors.

nice to see her coming home so soon johnny.
my suggestion... buy a 2nd pair of blowers, so when/if these go, you're not outta commission too long. and always have 1 backup set.

Those look like the Wiand blowers ( the later were B&M's)

The Wiands have a "W" cast in the front housing.

Mine have the Wiands, and they have oil in the rear.

I ended up removing the superchargers to change the oil.

It's not that big of a deal to do.

They don't hold much oil in either end.

The only problem I had with either of mine was
a small oil leak at the shaft seal, and that was an easy fix
also.


Great engines

I'm shure you'll enjoy them

Rob......I have already been in touch with the Blower shop about a backup pair....the snout seems to be the only problem for getting a backup but they are working on it....and yes she should be at her new home soon.......

JayTee......that is what I thought from all of the researching I have done on OSO........is there any way to suck the oil out or is removing the Blower the only way....

At 200 hours you should be fine.
Mine were rebuilt @ 290 hours and they looked fine. 20/20 hindsight, I could have gotten away FINE w/ changing valve springs.
Also had Blowershop rebuild and upgrade blowers About $2K for both.
Great motor! Reliable and fast. Check the front thermostat housing - esp where the hoses connect. They like to corrode there and close up the passage.
Do a search here and on Speedwake for 575SCi or just 575. Lots of good info!!!

I have early production 575SCi's.

There is oil reservoirs front and back. I watch them
like a hawk and change the Merc drive oil in them
yearly.

At 430 hours and 5 years I've just completed a head
overhaul on one engine (tired exhaust valves). And
the head gaskets suck although I never had a failure
due to them.

Watch the diaphragm fuel pump on the raw water
pump like a hawk too. Especially every year take it
off and change the oil in the little reservoir.

But what do I know. I'm not a marine mechanic.

I have a pair of 2002 575's and here's my advise (for whatever it is worth). I had a blower fail last year at 250 hours. I don't run my boat real hard, but I do lean on it. I bought the boat new and have changed the oil in the blowers annually. By the time I could hear the rotors colliding, it was too late. They were bent and I had to fork over $3500 to the blower shop for a rebuilt blower because no one makes rotors any more. Mine are Weiand. Now at 280 hours I just had a head gasket fail. I love the motors but highly recommend you rebuild your blower every 200 hours or less! The cost is $400 from the blower shop compared to $3500!
