I have a 2007 GW 257 Advance and the YAMAHA-ROT got me on my Yamaha F250 with 578hours. I am having the dealer swap out this motor for a brand new 2026 Honda bt350hp! I cannot wait and the deal Honda is doing for repower is unbeleivable! Plus a 5yr warranty! I could not pass it up. Wanted a Mercury 300hp but it was going to be 25k high, double the price...... So i dropped it off May 2nd and hope to get back soon and i will post some info on speed, GPH and thoughts.....

Anyone do this yet?? 7614.jpg

Granted, Honda isn't as "new" and advanced as the Merc, but... $25K difference?!?!!? Holy cow! That' s GIGANTIC difference and more than makes up for any "betterness" of the Merc! Is that word? :p

Is something going on with Honda that they're trying to liquidate their engines? That's an amazing price.

they are setting the stage to make the 350hp block 500hp+ and getting as many 350's out there so when they introduce a 500hp+ it is not a shocker it will be a proven motor/Block
 
As mentioned in another thread... it seems very odd that they're discounting the Honda 350 by like $10k+, as it's essentially a brand new design that they've come out with only in the last couple of years. It almost seems like they're going to go with a different design or they aren't selling very well, or something similar. I think that I personally would go with the Suzuki DF350A if I were in the same boat as you are, pun intended. It's about 30 lbs lighter, can oftentimes be found in that $20k-$25k price range as well, it also comes with a standard 5 year warranty and is a 6 cylinder vs an 8 cylinder... so it'll likely do a bit better on fuel economy. Sounds as though you're happy with your selection/purchase, good luck with the repower.
 
I will take a V8 over the v6 anyday. The v8 has more torque, can run at lower RPM and from what they are saying we shoudl be close to 3miles to the gallon! Honda is setting the stage for 500+HP but needs the people to love the 350hp first so they are getting them out there!

Any pics of the mustang? I own a 66FBK mustang. All original california car. Been in the family since 1970....lol

It's interesting because people keep talking about torque numbers and so forth, yet I don't think any outboard manufacturer actually posts their numbers for ft/lbs of torque. I imagine that the Honda 350 likely has more torque considering that it's a v8 as opposed to the Suzuki considering that it's a v6, but yeah... not sure how to prove that at this time. It is also another great thing about the Suzuki in that it does run a lower gear ratio, so that it can use considerably larger diameter props and have a good deal of low end torque to them. Might not exactly be to the same level as a v8 outboard, but imo I'd sacrifice a few ft/lbs worth of torque for better fuel economy, especially if you need as good of fuel economy as possible for long distance trips, etc.

I do have a few pictures of the mustang, she's a 1965 fastback that the previous owner cut the rear vents out of and added the Shelby plexiglass windows. So, it's kind of more of a "Shelby look alike". I've had her since I was 15, so just over 25 years now, put a 351w crate motor with aluminum heads in her with 450 hp, 5 spd transmission, side exit exhaust, four wheel disc brakes, Foose 17" wheels, Ford 9" with 3.50 gears, updated suspension and so forth. I took a pretty cool picture at a car show up here years ago with the Paul Allen collection at Paine Field. Was really cool seeing and walking through a B-29 as well as several other WWII planes, a P-51 Mustang, a B-24, etc.

they are claiming on my 25cc 3 miles to the gallon! Not sure you can get better than that. They use a 2 stage/step cam for lower end and higher speeds to get better GPH. And unlike the Suzuki it runs on 87 octane!

Beautiful car. Here is ours.

I couldn't agree with you more - that's a big boy engine, for sure. I wasn't (still am not) overly famliar with Hondas of that size, but I looked it up and it's a solid 5 liters of power. I'll take that every day of the week over a V6. 'Course, that Merc V10 is a VERY cool engine... bigger, more power and decently lighter... but then we're back to the cost and it's not even close to what you got.

You got a heck of engine going on your boat!
