I first noticed PSI was zero on one engine, then immediatly 225 HP Yamaha 4 stroke got stuck in forward gear (even when gear shift was in reverse....not good). I first thought linkage, but with no psi showing in the guage I'm thinking lower unit leak? possible?

(removed email address per guideline #4 at the top of this page)

What PSI was at zero? If you're referring to oil pressure, there's no monitoring in the gear case, and if no engine oil pressure, that would cause catastrophic engine failure. Do you have the electronic shift or cable shifting?

Robb, I assume you mean your water pressure went to 0 and then you were stuck in gear. The water pump and gearbox are completely separate systems, although they live near to one another inside the lower unit, It is hard to imagine what would have affected both other than catastrophic damage - did you by any chance hit anything recently? In any event you will need to drop the lower unit and check it out.

You may wish to clarify which F225 you have - the 3.3L with mechanical controls or the newer 4.2L with the electronic ones.

Thank you gentlemen. I appreciate your comments.

The PSI gauge that showed zero is for the starboard engine oil pressure (unless I'm totally missing something) and while it showed zero I doubt it's t a gauge failure).

Things in general are a bit vague as I just purchased the hull with plans and budgets to repower with fresh yamaha's (250).

I am holding off repowering in order to buy 2017 engines and not really using the boat, specifically becz the mechanics survey show port engine cylinder #5 had minimal compression and I will be trading-in both engines.

Worth noting that the starboard engine (Yamaha 225 (400 hours, 12 years old)) had a clogged injector (per mechanic's survey) so there could be mitigating circumstances with this. But stuck in low rpm forward? Have not hit anything below water line...but appears I may be expediting repowering now....I just couldn't track the low psi with the gear problems.

Hi, hate to tell you that outboard engines, no matter what make, don't use model years anymore, haven't for awhile. If dealer is telling you that the engine(s) are a 2017 model year, ask the sales man to prove it an watch him/her back up like a crab.

10-4 - thinking it through, the year of the engine purchase probably wouldn't matter as much as the remaining warranty down the road - but point taken......

If those are 2003-2006 engines, this model is also notorious for corrosion problems, as in the bottom of the crankcase rots out and loses all the oil. Could be why you lost oil pressure. Happened to 2 boats at my marina and is a known issue.

I'd also look at Honda 250's if your hull can handle the extra 60 pounds per engine. 330 flawless hours on mine. About 30% more efficient at 3000-4500rpm than most engines and very quiet.

In the last 2 years, a Yamaha 300 hpdi with 400 hours has blown, 2 F225's with the above mentioned corrosion issues, and 3 weeks ago a 2013 F250 (luckily under warranty) blew, not exactly an awe-inspiring track record.

Thanks again. I'm all over the corrosion problem, occurring in the dry exhaust area and it crossed my mind as well that this could effect both PSI and gear problems. This is why I'm repowering, but will look into the Honda's - I've heard good things about Suzuki as well as Yamaha, and Merc. But extended Warranty is the key issue.

Robb,

What year is this boat?
In post #4 you say it is a 2012 model.
In post #10 you say it is a 2004 model.

A little confusing to many of us along with what year the motors might be.

OK, with the new information that it's a 2004 motor and oil pressure, not water pressure, went to 0, it seems likely you encountered the dry exhaust corrosion problem, and your motor is now completely toast - that is. it would cost more to fix than the result would be worth.

Regarding new motors, it is true that Yamaha and other manufacturers don't have model years any more, so there is no reason to be waiting for next year's model. And if you're considering Yamahas, and extended warranty matters, why not take advantage of the promotion Yamaha is running and double your warranty from 3 to 6 years? They run this promotion every fall, and this year it is available through November 22.

Thanks Tedious,
This was my strategy, waiting for the fall promotion by Yamaha and knowing I would have to budget to repower, just didn't think the engines would fail on que like this, but I can get the boat to the trailer on a single screw easy enough, then off to the yard. (am assuming its the corrosion problem even tho the oil PSI is a measurement of the upper unit, as opposed to the lower where the corrosion occurs. Do appreciate the feed back.

The Honda standard warranty is 5 years. Something else to consider.

Maybe this is brand new or maybe it doesn't pertain at all, but I thought I just saw a television commercial for the bigger Yamaha outboards during my Saturday morning fishing show lineup and I swear that Yamaha was touting a 5 year warrant for their bigger outboards, 200 and up I believe. I know when I bought my smaller Yamaha F70 last year a $500 rigging allowance was offered as a choice against the warranty extension. Maybe Yamaha is trying to compete with Honda's warranty?
