Yamaha 225 4STROKES!!!

[tags11]

I'm looking to re-power my boat. It has twin 97' Yamaha salt water series 225's. The engines run excellent right now and i suppose i'm happy with them. The main reason i want to re-power is cause of gas prices and reliability. with the amount of fishing i'm gonna b doing in the next few seasons, savings in gas might be upwards of a few thousand a season. maybe someone can give me a better guestimate?! anyways, if anyone knows of anyone that wants to get rid of a pair of 225's that are only a few years old with low hours let me know! also, r there any outboard dealers that might have leftover models? seeing that the markets slow, maybe its a good time to buy some engines? thanks for any advice you guys can give! tight lines everyone!!! -tags11

this is kinda interesting...
first what is the make and model boat you're gonna repower ???
with the weight of those engines,versus what the old engines weigh,it could cause a significant problem...if you've got a bracket equipped boat,the problem will be worse,due to the leverage effect...

next point...fuel savings,how often do you use the boat ??? trying to make up the initial outlay of $30k for a repower,by what you're gonna save on fuel-that could take a looooooooooong time....

Its a 30' pursuit. it can handle the weight of new engines. and your right, gas savings of $30,000 will take a long time!! i'm not exactly sure what the hours of this season will bring, but the boat will hopefully be used 3-5 times a week from april-october for drum, then shark and tuna. I have no idea what gas savings could be. I REALLY WANT PEOPLE'S GUESSES ON GAS SAVINGS! I figured that if i can save a few thousand a summer over a few summers, and depending what i'd get for my current engines, all those factors added up might make repowering financially more feasible. SO..... depending on what gas savings could potentially be over a season multiplied by a few seasons, and the decreasing value of my engines over the next few seasons might have me repower now rather than wait a few more years. If i wait a few years then i'll have to put more money out for engines (as i'll get less for mine) and i may have already paid thousands extra in gas. Maybe i'm right on this whole repowering thought, and then maybe i'm wrong! either way i'd like to figure it out with the help of SFC! thanks guys!

I think trying to figure gas savings maybe hard, but give this website a look.

Yamaha website on performance and the test results of different engines on different boats.

Maybe not your exact boat, but you can get the weight close.

Best of luck. TODD

What model pursuit??? We had a 3070 offshore CC and we had 250 sws yammies and we thought about upgrading to 225 yammies but realized that boat is way to heavy for that power....check out the twin 300 suzuki 4 strokes for that big a boat.

I've gone thru the math over and over myself, due to having my 2 strokes nickel and dime this past summer. Hopefully, this was fixed by a new service provider. HOWEVER, I can still see no benefit in repowering with the only the savings of gas in mind. Last year I was getting about 1MPG on my two strokes (225 Suzis/30' Mako walk). I made some changes to boat weight (taking off ANYTHING I don't need for fishing and removing an unused generator) and started adding DYNOTABS octane booster to my fuel to add 1-2 numbers to octane levels. I also started keeping my boat in dry storage after sanding off as much of the bottom paint as I could. These changes resulted in an astounding 25% fuel savings. Yeah, OK, so I now get a 1.25 MPG. But that adds up quickly for me and my guests. So what cost me $4k last year is $3k this year, not bad.

When looking at 4 strokes, I found that most dealers were rather hesitant in exacting fuel savings, though most offered that I could expect 1.75 MPG should I repower. At roughly 30% fuel savings per a 100 mi trip 15 times a year (for me), I could probably expect to save 450 gals a year/$ 1300.00??

Two stroke oil vs the cost of the changing oil, etc. seems to be a wash...

So really, at $1300.00 a year savings and hell, I don't pay for the gas most of the time anyway, my crew shares the cost..., I could figure about 23 years to break even?????????????????? (And remember I share gas expenses) My shyte has got to die before I consider repowering.

Just my 2 cents... or $1300

Thanks to everyone so far for posting. its the 2870, so i guess technically its a 28'. I'm used to saying overall length (30'). keep'em coming. i really like hearing what u guys think. should i be worried that the engines r getting a little old? (even though they're in great shape). can someone explain the octane boosters that bitemysister was talkin about? its sounds interesting...r there positives and negatives? what do they cost to add? THANKS!!!! i know its still the winter but i cant wait to get that first line wet!

We purchased our Islander 270 new in 2002 with a single 250HP OX66. We cruised at 22-25kts, at about 1.2-1.3 nmpg. We also used one gallon of Yamalube for every 33 gallons of gas overall - with little variation based on speed.

So, eight offshore trips would be about 1080 gallons of gas, plus 32 gallons of Yamalube. And 100 hours of engine time. Gas at $2.50=$2,700, plus Yamalube at $18=$576.

We repowered last year to twin F150s. We now cruise at 28-30kts, at 1.6-1.7 nmpg.

The same eight offshore trips now will take 760 gallons of gas, no Yamalube, and one oil change. So, gas would cost $1,900, plus $100 for the oil change.

Overall, a savings of $1,276. Round it up to $1,300 for the savings in using less Ringfree.

At $3.00/gal, the savings go up about $160.

Now, will the savings EVER pay for the repower? No. But we now have a faster, quieter boat that can get us out to the offshore fishing grounds w/o having to carry extra fuel, and jugs of Yamalube.

Just a quick note on the boosters, since I can go on forever about them. I did extensive research into and found that, after talking to engine mechanics, manufacturers, booster makers, internet research, etc. the people of DynoTab had the best SAFEST product around. It will not harm engine components!! With their product, its NOT possible to add too much booster to your fuel no matter how much additive you put in, you're gonna get 1-2 points of octane, no more, plus better burning fuel. So what happens is... it allows me to buy 87 or 89 octane, make the add at $10.00 per 100 gals and walk away with higher octane needed for older two strokes at less cost than buying 91. The product is a solid tablet, so it takes the guess work out of adding it as well as potential mess and another empty bottle to toss. Additionally, you have the luxury of being able to boost sitting fuel (though not junk thats been in your tank for 2 years) a couple points, as octane levels reduce when gas sits in a tank.

While this may not be the answer for everyone, it has help me to get better gas mileage along with the changes I made previously.

Please check out their website and give them a call. The owner will come to the phone and send you info as well...

biggest problem with repowering with f225's or f250s is that the engines are wide motors. they may not fit or you will have to have the mounting holes redone. My buddy has a 25 grady sailfish and they would not fit.
