The bulk of the problems started with the 2005 production year. As mentioned, there is no factory warranty. Even if the seller or dealer gave you a warranty it would be for a short time and most likely before you have a problem.
Who are you buying the motor from?. If a dealer, ask them to state the condition as they see it in writing. They may not know about problems, but if they do, they legally can't lie.
Of course proving that later on is not a simple task.
Regardless, have the exhaust scoped, preferably by someone other than the seller ( Having it done by the dealer is OK as long as they will put the results of the scoping in writing.
Nothing was mentioned about a dealer so just took it as buying from an individual. Be surprised if a dealer offers any more than a 30 day warranty. Biggest issue is the exhaust, make sure that is done or deducted out of the price if not done.
Thanks Ky, Fishtales and Seasick! Appreciate the responses. I am talking to a Boat Broker who works on G-Ws and Yamaha outboards in the MA area. He has a 2004 F225 which he will install on my Seafarer 228. He is offering to warranty the engine for one season, we are discussing the details. I am concerned about the corrosion issues with that vintage, not to mention that the motor is 15 years old.
I had a pair of 04 f225, they were replaced in in 2017 due to the corrosion issue extending into the engine. I will tell you the 04 even when the corrosion was discovered were running perfect.
They were extremely dependable for the 13 years I owned them. Aside from routine maintenance they never had a single repair needed. I hear from many that once the exhaust is replaced those
engines continue to deliver for in some cases thousands of hours. One season warranty is a good insurance on a 15 year old motor. Good luck
I have a '04 F225 that the exhaust was done 2 years ago and it's running well, 1278 hours. As long as the corrosion has not gotten into the oil pan or eaten into the mating surface of the power head, replacing the exhaust is a fairly easy fix.
Does anyone know if Yamaha is still offering the exhaust kits at a discount? It was $600 I think with the discount. Add labor in my neck of the woods and the job would run $1500 to $2000 . The kit didn't include the oil pan or the oil pump which should be replaced when the power unit is off.. So what would you negotiate as a price? I suspect that the motors don't have a lot of value, maybe $5500 or thereabouts.I watched one job getting done and I am not so sure I would tackle the project by myself.
I have two 250s with manufacture dates of 2006. One of them was corroded by 2011 and had the midsection done, including the oil pan. The other one has been scoped twice, last time in 2017 and is fine, no change since 2011.
When looking at the 04 F225, be sure to check for corrosion at the thermostat housing, both sides. The corrosion can go through the block and the engine will ingest salt water. Pull the thermostats and feel inside the block - if there's corrosion, it will be quite evident.
From memory, not at home, 04/06 on the one with no corrosion and 05/06 on the one with corrosion. I seem to remember asking myself that question and was puzzled by the fact that the earlier date was the non-corroded one. Good question though, I'll check next week if I can remember. I feel certain one was 05/06, but not positive which one.
