Default Considering buying 2004 Yamaha F225's and have questions

I'm looking at 2004 F225s with 25"lowers 950hours, exhaust update done recently also but doesn't include rigging or controls. My boat is 2001 Aquasport 275 Express same as wellcraft 270 which is the more common boat of same design.

What is a decent price for the pair?

What would rigging and controls cost ? I have mercury Optimax 225's so would need to completely change everything. I assume control cables are different ends and need different also?

My initial plan was to eliminate my analog merc guages and link to my Simrad Go12 MFD. Would these Yamaha 2004 be able to plug into mfd or will I need the Yamaha digital smart guages?

I'd love newer motors but costs are limiting factors.

16 year old engines with relatively high hours on engines known to have exhaust corrosion issues? Is this really an upgrade? Are you having major issues with your current setuo? If not, I fear you may be switching out a lot of things for relatively big $ (unless you get all those swap out parts used too for a deal). I just dont think you are going to get a huge amount of longevity from them and will drop some pretty decent coin on them.

I agree with Smoke - it seems like a lot of effort for not much gain. If you compare performance bulletins, I think your Mercs probably compare pretty favorably with the older F225s.

The F225's already had exhausts redone this year so non issue.

Yes, I bought these motors last spring and was told they had around 850 hours. I installed them and initially first few trips loved them with only some minor hesitation/hunting at idle on port motor. Then had overheat alarm issues on starboard that I had worked thru from all new pump, t stats, back flush cooling stem thru block down to pick up tubes looking for debris. Ended up being bad sensor after last error showed 1500° temps. Lol . Port motor had a complete shutdown while on trip to Montauk without any hint of restart limped in trailered home because couldn't get mechanic available to diagnose. My mechanic found burnt out main switch relays due to wire corrosion, cut out replaced $10 part. Ran boat few more times had same thing happen. Brought boat back to mechanic and had him go thru motor with fine tooth comb. Found more corrosion cut back main harness even farther chasing it, my fuel/air rails are out of spec, most electrical components seemingly have higher resistance readings than spec calls for so basically to replace all the components just isnt productive financially. Oh best part is when at shop hooked up to computers both motors have 1600+ hours on them and I was lied to by seller on condition at sale.

from what I'm hearing is tons of people love Optimax motors but say they are complex and temperamental even my mechanic. He's pushing me to go 4 stroke I'll be it much newer that these 2004's.

My suggestion would be to get rid of the Optimax. They can be a giant PITA.I recently sold a pair of 2005 F250's with 2,000 hours for $13,500. That included all rigging, gauges, cables, props and every nut and bolt that was part of the factory installation. My motors had high hours but were extremely well maintained and ran perfectly.
I'd suggest used Yamaha F250's but I'd look for the latest models that fit in your budget. The current 4.2 liter V6's have been around awhile and are available in both fly by wire and cable operation. Some of these engines are known to "make oil" but other than this issue they have an excellent track record. Check the classifieds on THT and also Parker Yacht in SFL sometimes has used motors. My experience is Ole Parker is very knowledgeable and honest.

They are good motors and think a fair price is around $8k to $10k without rigging. Also those are not NMEA 2000. I believe that came out in last 05 and up models. You will need the rigging. You may not gain much on your economy as the Optis are better and also realize that the F225’s put out about 207hp. You will also loose some performance due to the added weight and lower hp.

So in theory my older 1600+ hour Optimax motors would run about same as a good running good compression F225 correct?

Maybe. You will he adding more weight and have less hp. I think it would be close but the reliability should be better and the F225 are easy to work on.

This isn't going to sound good and I'm going to be honest. You installed an old pair of 225's with more hours than stated and a bucket of issues. If they lied on the hours, are you sure they did the exhausts? and didn't just slap the parts together for a quick sale? With all of your electrical issues, I also wouldn't doubt if those motors and harnesses got wetter than they should have and wouldn't trust any part. Even plugging newer 225's or 250's into the same harnesses will still likely have the same gremlins. Dumping $12K on 15 year old motors (plus a few thousand for transportation and install) is a gamble no matter how meticulous someone maintained them.

Get something a lot newer or use the old motors until you can get newer ones.

Don't do it.

I've see receipt of exhaust and picture on update for new Yamaha I'm considering also the computer's engine hour readout so I'm more confident and will do my due diligence with new purchases this one or another if I choose to pass.

Engine problems on existing Mercury is confined to the motor itself and wire corrosion is on main engine harness not the control remote and ignition harness so your incorrect. But if I choose to change brand motors all that boat side rigging is changed out anyways also nullifies that concern.

If I had 50k or available budget to go and spend on new motors I would have done so.... I would love to upgrade to newer used than these also but used outboard market is overpriced IMO because of the exorbitant amount brand new ones cost so inflated late model low hour motor values.

I was simply asking about these Yamaha motors compatibility to neama on MFD and some insight on performance and reliability. I've read a bunch and to my observation the Yamaha 4stroke is more reliable than a similar year hour Optimax. Optimax owners love performance and fuel efficiency but say temperamental and costly to repair especially with compressor and fuel rail issues that need addressing every 7-800 hours.

I think you will find those 2004 engines are not NMEA 2K compatible. The engines would need both the engine harness that includes the white connector with white and blue wires AND and ECM/ECU that outputs NMEA 2000 compatible information. Yamaha introduced that during the 2005-2006 period, so your 2004 engines are not likely to have the capability. Might have the harness with the white connector, but not the correct ECU.

IMHO, having to add all the Yamaha controls and a set of Yamaha gauges renders this a "good deal" only if the engines are FREE, including shipping.

The F150s on the boat in my signature were 2005 and I was able to add the Lowrance NMEA connector and get the desired information on my MFDs.

I was in the repower process for a couple of years. I had a 2005 Yamaha F225 with exhaust done and receipts for the work. When I started repower shopping the engine had about 1200 hours on it and was running great. I talked with 20+ Yamaha, Suzuki and Honda/Tohatsu Dealers at boat shows across the North East, I was including controls and gauges. Not a one was willing to give me even $2K in trade. I figured with so low of value, might as well run it till she blew up. Blow up she did at 1800 hours+.

I sold the now dead engine, gauges and controls on Craig’s List for $1200.

I can’t give you an exact value for what you should pay but given the extremely negative publicity those years of F225 are associated with I say $5k for the pair would be top dollar.

Not a bad engine if you get one that is running OK, but they’re not worth peanuts and at 15 years your getting close to antique status. Not really the place you wanna be on a saltwater engine known for corrosion issues and while midsection gets the attention NOTHING says corrosion isn’t going on elsewhere. I didn’t disassemble mine after she blew but I’m 99% sure a corrosion issue is what caused the water intrusion into the oil that killed it.

Guy wants 12k for the F225'S but figured if I could get for 10-10,500 plus 6-$800 for new Yamaha rigging.

Seams like the majority of you guys are against the swap. Do you guys think I'm better off leaving my better Starboard motor and just finding a low hour Opti to replace the problematic one? Definitely would be a much easier swap all plug and play at the transom and much cheaper.

Yes, replace Optimax and do what you have to do to get back on the water, knowing its a bandaid for now. But dumping $10k+ into those F225’s is insane. The guy will never get close to his ask price. You are better off financing new engines, those F225’s will be worthless in no time at all and you would wish you had that $ to put down payment on new engines. Consensus is here is you will lose big on this deal, we just dont want to see you make a major $ mistake and not have your expectations met.

Yes, for sure. The older F225’s are not good performers compared to two strokes and weigh a lot more.

Ok guys, I have a line on a 580 hour 2005 Optimax that was gone thru and serviced by mechanic and compression is around 110 in all cyl and fuel/air rail is in spec. (Tracker valve) I can get it delivered to NY for $4200 from Delaware.

I just sold my original twin 2001 EFI'S that came on boat for $5k so I'll be in the good plus still have the port 2004 Opti being replaced as a running spare or sell to recoup some cash.

What are your thoughts?

Only reason I was considering going Yamaha is because my local mechanic/dealer is not a fan of these Optimax. My orig plan I wanted to get brand new dressed Pro XS Optimax dressed blocks to drop on midsection but Factory won't allow it on my motor. Says exhaust tuner is different. So then thought of F225'S I saw.

I love the Optimax but if anything is wrong with Electrical system it could be very hard to figure it out. You can get a loan for a new motor for like 10 years at 5 percent I think. Kiss your wife and tell her you need her input, you don't know what to do, should you buy used and maybe have bad, expensive problems or just bite the bullet and buy new. Does she like the boat?

Haha, yeah that won't work with the Mrs. ....lol

If it were a single outboard I would be all over getting a loan but to be paying 700+ a mo for 10 years on 50k motors is hard to swallow....🤮
