460 hours and 6 years on two 575SCi's bone stock.
Part of yearly maintenance is to check the oil in the little drive unit for the diaphragm fuel "pre" pumps at the front of the engine by the raw water pumps (else they run dry and ruin said pump). The head gaskets suck. You're on borrowed time with them. Mine just failed leakdown specs at 450 hours so I refreshed the heads anyway. I have the early blowers, those are the reliable ones (although I did have to have one blower rebuilt when the boat was two years old, the blower was consuming oil). And that reminded me, keep tabs on blower oil. There are front and rear reservoirs. In general I'm pretty happy with them. Pesky Varmint |

Thanks guys !
I have been told alotta guys a running 89 octane with no issues .... Any of you guys have experience there ??? |
Very reliable stock with the above caveats (****ty head gaskets, blowers should be rebuilt at 100 hrs, mechanical fuel pump reservoir issue is common to several blue Mercs).
Easily modifiable for more HP. Likes more boost and intercooling. MEFI 3 is easily reprogrammed. I agree the 525 is also a good motor, but the computer is to my knowledge unhackable, making mods difficult. If you are leaving it stock, OK. But I think horespower is like t-ts, you'll rarely hear someone say "she has too much" :D......... Regards, Steve |
