2001 Mercury 175 EFI

[depbass]

Considering repowering with a 2001 Merc 175. How reliable are they and how many years should I expect for it to have left in it if its well taken care of? Motor is in good shape with average hours.

i owned a 2000 175 efi for about 7 years.(purchased 2005,sold 2012)the first 5 years no problems,the last 2 years it nickeled and dimed me to death.they are very strong engines that like fuel.most of the problems i had were intermittent electrical problems.also had problems with the oil injection,finally removed and started pre mixing the oil.i found out that most of the merc service techs did not like working on the efi engines because their diagnostics equipment would not hook up to a 2000 model engine.(i think you have to have a 2003 model or newer)so most of the time you were just changing out parts hoping that would fix your problem.the only reason i would not buy another efi engine is because no one in my area knows anything about them.if i lived in Florence i would probably own another efi engine because you are not far from mr.don weed.get to know him if you buy the efi engine.he has helped me a million times.he is located in Greenville sc.there is one other thing you need to do if you buy the efi engine,make sure you have the fuel rails,injectors,cleaned and calibrated.don can do this.thanks,good luck and good fishing

I have a 98 Mercury 175EFI. I've had it for about 3 years. It does suck gas. It runs strong. Pretty reliable. Its on a 99 Champion 187 Elite.

Built on the tried-and-true 2.5L Platform, very reliable engines.

My 2000 EFI was fished twice a week for 48-52 weeks a year for 15 years till it blew. One can only guess how many hours were on it. Did have to repair the ECU (Simon Motorsports) replace the voltage regulators and the tuner broke away. . It was a solid engine, the only thing is the fuel and oil consumption, terrible. Replaced it with a Pro-XS which is like getting a pay raise, it sips fuel and oil. Get it checked out by a good tech.
