BIG Question - replace Yamaha 150 HP with Honda 225HP

[willy]

I would not do it, because of what Ferm just said but also an assumption that you are gaining a good chunk of weight. That is never good. I do not know the specs between the two.
When you add another 100-135 lbs for a kicker also sticking out on a adjustable mount I think two three things will happen
1. Your bank account won't look so good
2. You will love the power and you will play with it a couple of times like a hot rodder but you will not use it much after that unless you are like Skools and like that G force facial expression he enjoys.
3. You will not like the arse heavy set your boat will take nor the porpoising you will experience and have to correct with a lot of positive trim tab.

Besides with all do respect to the four strokes out there which I love to you have one of the most reliable and best built engines ever put on a boat already with what is considered by many to be the ideal horse power rating.

I love my 4 stroke and would prefer never to own another 2 stroker.

That being said, if your 150 is running good, why replace it?

At $4/gallon you can buy 2412.5 gallons of gas times approx 2.5 mpg, you can go 6031.25 miles with your current rig for the price of the new motor. (oh, I forgot oil, like I said, I love my 4 stroke)

I don't think your mpg will be a lot better with the 225 Honda, I've heard that they are a bit thirsty for a 4 stroke, maybe 3 to 3.5 mph. (this from a guy running twin 225's on a 28' Mako CC)

It would take 10 years of running to make up the cost.


That being said, if you want it.......BUY THE NEW MOTOR!!!!! (its only money)

I say do it....no don't do it....no do it.....no don't do it.


Seriously, I personally would not do it for all of the reasons above.

of the 225's if you were dead set on a four stroke the honda would probably be the last choice. reason being there lower units arent up to par with the rest of the boys. main reason, plastic oil slinger and major issue with part interchangability. besides that head rebuilding and valve maintenence are a sinch with the hondas. also a yammie 150 stroke is a dog just like its fourstroke cousin. i ran both if then several times. if you would put a real 150 by either of the north american made companies you would see a big difference. the only thing you would have to change would be the wiring harness. since you can convert the box to go to either brand with 33 series cables.

Thank you guys for your two cents.

I will just go about with my current motor as this will be my 5th season.

About my V21 - I will post pictures for all to see. V21 is a perfect all around fishing machine and I run it with two cannon Mag 10 riggers, depth raider and Lowrance FF. Next month will be the beginning of the steelhead fishing and spring Kings.

How much better on gas do you find the 4s over the 2s? Lets say a day trip where you would burn 25 gallons with a 2s how many gallons for the 4s?

you cant say all 4's are better then 2's unless the 2's are carbed or efi. it is usually anywhere from 20 to 40% better except at w.o.t.

The 4 stroke is mostly better than a 2 stroke NON-DFI looper at idle and slow speeds. At cruise the 4 stroke is probably only 5-15% better, and at WOT they are almost identical. A cross-flow engine is a wasteful SOB at pretty much any speed over idle to slow cruise when compared to a looper, but a looper burns excess fuel at idle to real slow speeds vs a cross-flow. DFI eliminates pretty all of the down falls of 2 vs 4 stroke.

i agree whole heartedly with you!! lol

I think you'll have worse fuel economy with the honda 225 ;) There was someone here on the site that had a 225 Honda on the back of a v20 . . . if I remember correctly the boat cruised at 2.5 - 2.8mpg . . . and topped out at only 45mph. I'll do a search and see what I can come up with.
