No matter what I would replace the impeller. It looks like it has enough curl that it wont pump enough water as it is. Add to that big time centrifugal force at 5200 RPM and it curls up even more. Keep us posted we are all learning something.
Do any of you know where I can find the specs on a new Yamaha 250 carbed two stroke? the Yamaha site in the US doesn't list them even as a product, near as I can tell.

Try this link but your Spanish better be good. Mine is non existent. Those are the motors we sell here in the Bahamas also. Will check the local yamaha guy for specs when I get the chance.

Yes, and you better hope you don't need parts. Mexican marine houses stock nothing, are very expensive, slow to respond, and have horrendous export laws.
So if its not's for sale in the states, they probably won't carry much either.
4 stroke is the way to go with their 6 year warranties. The opti's and hpdi's have always been tempermental in 3rd world countries IMO, normal 2 stokes not that much better.
I have dealt with Immemsa and their parts and sales people know nothing more than prices.
Oh, I was interested in the specs on the 250, mainly the weight. 240 kg. I wouldn't be buying anything from Mexico.
I don't see me buying four strokes for outboards. I don't see any advantages to them at all. Heavier, more expensive, more complex, harder to work on, more moving parts...etc. Too much penalty for a slight mileage increase. Yeah, they're quiet, but I don't see noise as a determining factor at all. Thats kinda like saying they come in blue.
Gringo, does the local Yamaha dealer stock's parts? Like most likely parts for upkeep?
V
yeah, the local Yamaha guys are aces when it comes to these motors. I think the guys on Providenciales keep something like 100 of them going for the local fishing guys, and over on Grand Turk about another 50.
They stock parts, and the Yamaha mechanics here could rebuild one of these in their sleep I bet.
They just don't have any experience in the HPDIs. Don't sell em, stock parts for them, or fix em.
Seems like so as to keep constantly boating with no big issues the way to go is to take the boat of your choice to Provo and get the power set up once the boat gets there.
Yamaha only gives a 2 year waranty on on HDPI's and carburated 2 strokes, but and you can get a 6 year on a suzuki 4 stroke.
So I believe this is a true indication what the OEM's believe each one will last, and they have the expertise and warranty experience to make the call better than you or I.
So will a 4 stroke be more reliable than a 2? Would you also prefer a 2 stoke in your car?
The 2 stroke weight 528 lbs and the 4 st is 604 in a 250. But If you drop down to 90's like you are seeking, the weight difference is pretty insignificant IMO.
I don't understand, you have spent weeks on the 300 and have software to diagnose.
The fact that you don't have local support is no longer a big issue.
Order the maintenance parts filters and waters pump impeller and use the boat.
Seems like your problem was related to the popet value and old fuel.
Those were fixed so why keep the boat?
If you sell it you will get little of nothing for the engine.
I saw where you used Permatex on the VST gasket. I'm told it doesn't play well with injectors. Don't ask how I know.....
That may have gummed up the filtration between the VST and injectors but never actually reached the injectors.
funny you should mention that. I had a very similar experience. The permatex didn't reach the injectors, but it sure played heck with the filter. This is the original VST screen, which I cleaned in solvent and blew out with compressed air after this photo was taken:
Then I re-installed it. And SOMEbody, who I am not going to name because he is my son and besides I should have been watching more carefully, put the 0-ring back on the VST housing with some permatex. I told him to use a dab in the corners, outside the o-ring where it wouldn't get wet, to stick it in place......
Can you tell which filter was cleaned in solvent and compressed air, and then got re-clogged by permatex within an hour of being re-installed?
Here's a hint, the one on the left is a new one.
I pulled permatex 'spaghetti' out of the bottom of that VST, and cleaned it out of the o-ring groove with a little piece of wood I cut to fit the square groove.
I have learned. Don't use permatex. If you put that $ 30 O-ring somewhere to dry out for a couple hours, it shrinks back down to where it will fit. Kinda like the first filter on the motor does.
yeah, there are two pair of eyeglasses there. Different magnifications. Useful for picking little bitty bits of permatex out of things.
yeah, I tried to buy an impeller, or a water pump rebuild kit from local Yamaha dealer.
no luck, despite the fact that the impeller is common on almost all their two strokes. They don't have any in stock, and couldn't tell me when they would have some. Maybe a week. Maybe longer.
SO, I scratched my head on that one, for a bit. Would I pay $ 50-60 in FedEx or UPS charges to get a $ 20 part? Tough one.
But I am working something out. In the meantime, the weather tomorrow is forecast to be really good and we plan to take it out and see if lowering the motor a hole made any difference. I never run WOT in the real world anyhow. If I can keep it on plane I am happy. I would settle for a solid 3500 RPM with no temp alarm at this point.
