EFI 40 & 50 Honda

Dreamer · Once a C-Brat, always a C-Brat Dreamer- Sold 25 Feb. 2013

In Canada this Summer, I saw a boat with twin Honda 50s that had a EFI Logo. I thought, that's very cool for those folks with CD-22s to be able to have fuel injection. I just looked at the Honda Marine web-site and saw the 40s and 50s listed with 3 carburetors. www.Honda-Marine.com

Confused, I checked the Honda of Canada site www.Hondamarine.ca and there were the fuel injected 40 and 50. However, the new EFI 60 discussed in another thread was missing from the Canadian lineup.

A person has to do their homework to find the right engine.

I wonder if US dealers will service the Canadian EFI models? Marc? Matt?

The EFI 40-50 is available in the US and is advertised. You can still get the carbureted engines as well and I suppose Honda will advertise them until they are gone. They are definitely cheaper.

With all of the problems we have in the Midwest with ethanol and fuel breakdown I would not recommend carburetors to any of my customers if there was an injected option. I suppose if you were in a desolate area with little or no dealer support or shops who could not effectively work on EFI, or doing your own service, then I guess the carbureted engine might be a good choice.

I'm in agreement with this for many reasons, but it seems counterintuitive.

You'd think the low-tech carbs would suffer through bad gas better than the high tech fuel injection with it's small orifices and exacting nature.

But we all know how the carbs get gummed up , particularly the idle circuits, on gas left in the bowls, and fuel injection systems, with their extra filtration, high pressures, and (I think) smaller amounts of residual fuel in them, seem to quickly blow the old fuel through them and get on with life and some new gas.*

*Sweeping Generalization Warning: that statement is not always true, and the exceptions to it numerous. Nonetheless, there is, I believe, some truth to it, and perhaps our professional mechanics and other experts can elaborate on this subject.

Just thought I'd comment on the paradoxical nature of the subject on first thought, and what I think may be some of he reasons fuel injection systems offer their advantage in this respect.

Right on, Joe

From my experience all most all EFI issues come from electric fuel pumps when engines are stored with fuel in them for over two seasons. I have had some so gummed up I figured the whole system was shot. To my surprise, cleaning the vapor separator and installing a new pump puts things right back where they need to be. I have only installed new injectors in some of the Yamaha sourced 225 Mercs the Coast Guard used here in St. Louis. Really bad fuel obtained on the river was the reason for the repairs. In fairness to carburetors, this was the same fuel source we used to run in the the older carbureted engines with little problem.

Almost all new boat/engine buyers just want to turn the key like they do in the car and go boating. Almost all of the rigs are trailered and fueled at the local gas station with fresh E10 gasoline. EFI is the best option for the vast majority of all my customers. It is a real bummer to tell a new boat owner that his carburetors are varnished and we can fix it for several hundred dollars. Nobody wins in this scenario.

Fuels vary widely around the country. I would recommend speaking to the local shops to see what problems they are seeing and if they recommend EFI or Carburetion if you are contemplating a new purchase. Stabilizer and frequent use are the best defence for either system.

Happy Labor Day everyone,

Randy , I agree 100% on your carburetor thoughts . Stabilizer every tank and we don't sell em anymore if possible either ,as we are tired of dissapointed customers!
