Default New Honda BF225D repower

Lots of threads about what motor to repower with and most forget about Honda. They are not fancy. Usually just known for reliability and fuel economy. These two things are what matter most to me. I decided just to stick with Honda because I sold my last 2009 Honda BF225 gave me excellent service up to the day I sold it with ~3500 hours. (hoping the new owner gets plenty of time out of her too). Other than replacing the lower unit at 2000 hours (most likely due to line in the prop) and a couple of o2 sensors replaced over 10+ years, the motor gave me no trouble and still never left me stranded.

The new Honda motors not only have a new look on the outside but some new features, most of which seem to make the motor even more easily serviced. The new v6s also sport a heavier duty lower unit with a 2.0:1 gear ratio vs the old 1.86:1. Honda also claims that the motors are even more corrosion resistant too. Although I never really had a corrosion issue over 10+ years with the last motor.

I will try to run her tomorrow to do the break in before I start guiding again. If I see any significant performance changes I will note here for future reference.

Here are some photos of the old and new.

I've got a Honda 60hp on my Hobie Power Skiff, and I like it just fine. If I ever go with a boat that could carry a V6 outboard, I would certainly take a look.

Today would not have been a good day for your speed testing though- the waves were rolling across the bay pretty good.

I mean bad publicity is publicity after all, right?

I still have not made a decision on what power Iím going with on my new boat, I may give the Honda 250ís a try . Does Judge service your engines as well?

I recently replaced my 208 F250 with a BF250D. I've had good experiences with boringly reliable Honda engines in the past. I put over 3500 hr on an 8 hp kicker when I lived out west. It was still running fine until the guy I sold the boat to broke it by hitting something at a gas station. The 90 hp main engine on that boat is now almost 22 years old and still running great. Both I and the new owner were very fastidious about fuel quality and the carbs have never been cleaned or rebuilt. The only issues with either engine were periodic thermostat failures and a starter replacement on the 90 hp.

The new BF250D is big and fat, which changed the center of gravity on my Grady, but in a good way. The boat no longer bow steers when off plane. The engine is quirky relative to the F250. There is not a lot of torque until over 4200 rpm, so the boat doesn't jump up on plane the way it did with the 3.3 l F250. It also seems to wander between the lean burn and BLAST valve train settings when at cruise around 4200 rpm. The rpm alternatively increase and decrease when the boat is operating in rough water. This is a minor annoyance that can be overcome by running at either a higher or lower rpm. I was initially disappointed in the fuel economy, but I found out that the motor was mounted too low. I put on a manual jack plate when I repowered and the engine needed to be raised in order to compensate for the setback. I'm now getting slightly better mpg at cruise than I did with the Yamaha and about 20% better mpg at higher speeds. The WOT speed is about 1 mph faster than with the Yamaha. Since it's on an offshore boat I really don't care about the weaker hole shot.

I was impressed by the relative accessibility of everything under the hood when I did the 20 hr service. The service manual isn't out yet, but it looks like the engine will be easy to work on. They did away with the oxygen sensor on the D models, so that should increase the reliability.

So far there is no indication that the Honda is making oil. That was the reason I replaced the F250.

I like boring motors. That means I dont think about it and know it will consistently do what I need it to do. I can then get my excitement from fishing and other stuff.

Outcast, Judge Yachts did the repower and does some of my service. However, the motors are Honda minivan motors on their side and it is easy to do most regular service work myself. I also have BOE Marine, who is on Kent Island and very close to me, as my local Honda dealer. They have been good to me when I needed something. (note that Judge is only an OEM supplier who only works on boats they built. They are not really a "servicing dealer").

Doc, Service manual came with my motor and they are available online here: https://cdn.powerequipment.honda.com...X31ZVL6020.pdf Also note that hole shot can be greatly affected by how you prop the motor too. I decided to swing the largest diameter I could since I push a 27'er with a single 225 usually with heavy loads. I swing a 15.75"x15 prop. However. My boat has 12 degrees of deadrise so she planes off easily.

I am hoping to get at least 3500-5000 hours out of my Honda like I did the last one. Heck a commercial crabber friend just repowered his boat that had a 2006 Honda 225 and he had over 8,000 hours on his.

The most trouble free motor I ever owned was a small Honda. And Iíve had Yamaha and Suzuki. Honda makes a great product

I maintained cable controls and it was about the same as a Suzuki with cable controls. I am sure the digital control motors are the same as well

Great choice, Honda is the best engineering company in the world, they have made and make some amazing engines.

"Doc, Service manual came with my motor and they are available online here: https://cdn.powerequipment.honda.com...X31ZVL6020.pdf"

That's the owner's manual, not the shop manual. According to Honda US, the shop manual should be available in October.

I haven't owned anything by Yamahas since my first new boat I bought in '86....until I got this rig..

What I like about the motors in addition to the almost troublefree operation is the fuel mileage and the quality of the Honda parts.

After putting 200 hrs on the boat (480 total hrs) I replaced the impellers. I went back in after another 200 hrs and the two that were on the boat looked no diffrerent than the two new ones in my hand. I wont even think about changing for another year or so.

I did have to change thermostats...but they are easily accessible on the top of the motor and it was quick and easy.

If I ever need a repower, I would look hard at the Tohatsu 250 version that I have found for around $15k. I have the capabilities of doing the changeout myself.

Even the stock Honda prop hubs lasted twelve years, when I spun one and had both redone. I dont know if they make their own or if they are made by a major supplier..

I spent the afternoon breaking her in. After a few hours at under 3000rpms, I was able to run her a bit, including a couple WOT runs under 30 seconds.

Previous motor was pre-NMEA2000 so I didnt have very accurate fuel flow. Cool to have that through my Furuno TZT2 now. Looks like I get 2.0-2.3nmpg (2.30-2.65mpg). The worst I saw was about 1.8nmpg running in a 2' chop with the nose buried a bit. In the river, I topped out at 33.2kn (38mph) as the fastest right around 5750-5800rpms swinging a 15.75x15" Honda Prop (Solas Lexor Plus). The boat had all my fish gear in the cabin, fresh heavy coat of bottom paint, 2 adults or 1 adult and 4 kids on board (dropped off my adult daughter and picked up my younger daughter and her friends). Fuel was probably about 60 galof the 110gal tank. No ice in the cooler.

I may be able to come up a hole if I try another prop. I am considering trying a smaller diameter Merc enertia in either the 15" or 16" pitch.

Note all speeds are in Knots, not MPH







BTW triumphrick, Solas and PowerTech make the props for Honda.

That would be an excellent choice.The Enertia / Q3 will tolerate very high motor mounting heights.

does the enertia push heavy loads well despite its smaller diameter.?

Do not be fooled by the relatively small diameters. The 15” x 15” is a whopper of a prop in terms of blade area. I am sure the 14-3/4” x 16” is proportionally similar. Comparable blade areas to many four blades, but with less weight and drag.

Yes the Tohatsu's are a viable option if repowering,as running gear is included.They are the older model Honda's but at the price who cares if proven reliable and bullet proof.
