2007 Etec 175 Questions

[Rybones]

Well put Bushwacker, that would be my sentiment on the torque aspects also. I am alsoaware of the VST filter and have reviewed information on extracting and inspecting that but haven't done so yet, its on my list.

As far as NAEBM and the Etec, is is my understanding that aside from the plus or minus 10% of HP rating the only difference between the 175 and 200 is the EMM settings, in fact that would be true for the 135 to 200, but the 135 and 150(?) have some physical exhaust port (or something to that affect) differences.

Regarding fuel lines, the boat had all fuel lines replaced 2 years ago, aside from those what lines (on the engine) are you referring to?

I cant find a Fuel Injector Man in Venice, but I found the same name operating right here in Naples, I think its the same guy.. maybe he moved..? Or did you just get your Italian cities mixed up. : ) He seems like the real deal and thanks for that nugget of info.

My etec guy seems ...good... and fair but I don't think he has the deep knowledge and experience with etecs that I want from someone I call "my mechanic". Looking for a recommendation for some one to make all the connections and fine tune it after I hang the engine. I want at least one really really seasoned guy to thoroughly go through the engine and correct any deficiencies that may have been missed. Iv'e been slow to hang it for just that reason. I'm willing to travel to east coast or perhaps even Tampa. Any suggestions from anyone?

Hey Ryan, have you dealt with these guys or heard anything on their service department? Not too far from you.

My new bride is Italian and she keeps me mixed up all the time!

Yes, I’m sure Fuel Injector Man is in Naples, not Venice. How fortunate that he’s right there in your backyard! I’ve spoken to him and he seems very knowledgeable. He used to be a devoted Merc/Yamaha fan, but said the E-TEC injectors produce the most beautiful spray pattern he’s ever seen and that made him an instant convert! He was so impressed with the design of the injectors and of the overall engine that he put a 175 E-TEC on his personal boat when his old Merc died.

In a 2-stroke motor, the vertical location and dimensions of the intake and exhaust ports, relative to the piston, determine the timing of the intake and exhaust events, much like the camshaft determines valve opening timing, duration and overlap in a 4-stroke. Even though the basic block dimensions are identical on all the 2.7L motors, it’s possible there are some subtle differences in the port machining between the 135 and 200. On any naturally aspirated engine, the hp/cubic inch ratio is often a good indicator of an engines temperament, i.e., low numbers = smooth idle, good low end torque; high numbers = rough idle and weak low speed torque but lots of power at high rpm. Boat surveyor Dave Pascoe said to beware of heavily turbocharged diesel engines that produce more than 1 HP/cu. in., as their durability is often no better than gas engines! The old marinized Perkins tractor engines in my trawler only make 135 hp @ 2800 rpm from 354 cubic inches, but they’re turning big 4B 27x21P props and will really make this 30 ton boat jump if you goose the throttle at idle! Very handy in close quarters maneuvering! They will easily push the boat to hull speed at about 1800 rpm, burning only ~ 2 gph each at ~ 8 kts.

Yes, Don they are 2 buildings over from my shop. Nick is the owner, nice guy, not cheap, but he did let me borrow a lifting ring the this engine, instead of making me buy one. He sticks very tight to MSRP. But they do have all the parts I've ever needed in stock and Juanna is parts is super nice, so I've got that going for me. I haven't yet used them for service because I had been using Ronnie at Phantom Marine. Very knowledgeable, through, super reasonable and quick. But he doesn't do Etecs.

Denny, Do you know if the Fuel Injector Man does Etec service and rigging? I guess I could call and ask.

He only cleans injectors. I did my own rigging and service. Those motors are fairly simple to work on, so get a service manual and do it yourself. You can also download an installation manual from the E-TEC site.

One thing you need to have done after installation is have a dealer run the fuel system restriction test. They tee in a vacuum gage in fuel line between tank and motor and then use laptop to run fuel pump at max flow with a fuel line putting it back in your tank, but don’t need to run motor. I think limit is 5” Hg vacuum. It’s required on all new engines because they’ve found some problems on the boat side on repowers. These new engines run so lean that they won’t tolerate fuel starvation that leans them out further. I bought a vacuum gage for the Racor filter that records max vacuum and lets you know when it’s time to change the filter. I think I did a post on that.

its 4 inches of vacuum, the best way for this test is to run the boat. That way you doent need the computer
