Wrenchin 2, I need some help

[rick09_99]

Recently, my water pressure gauge stuck on my stratos at about 15 lbs. It has a 2001 225 Evinrude 'Rude Ram engine. Seems to still have good pressure judging by the stream, but can't always go by that. Also, I had a new powerhead put on last year and it just doesn't want to run like it used to. Used to run 76 mph at 5600 rpms. now I do well to get 60 mph. Anything you can tell me would be greatly appreciated.

If it stays at 15PSI with the engine off, then the gauge more than likely has frozen with water in it and damage it. VERY common and a new gauge will take care of that. Just make sure to blow out the line.

That is a very big loss in speed!!! Do you have any ideal of how many hours is on it??? Is the check engine light on? The 3L family has a 200, 225, and 250. According to one of my replacement power head books, the 225 and 250 are the same engines with the 200 being different. If the power head was replaced and not rebuilt, you may have gotten a 200 and would account for the power loss.

Skeeters engine I recently modified was a 200 OMC (Johnson/Evinrude) on a 20' Javelin and it ran 62.4. After being built and modified to a 250, it ran 75.9 the other day. This is almost backwards to what you have. Some of the H.O. engines are very strong. A 225HO and 250 are almost identical engines. Example is a carburated 225 H.O. is about 245HP.

Where are you located???? I have a program that is suppose to work on the EMM (computer) on that year and we can take a look for codes, hours since break in was innitiated, data stream and see if anything stands out. Just a thought.

I live in Spencer. It is a new powerhead, not re-manufactured. I dont know exactly, but would guess maybe 50-60 hours. it would surprise me if it was a lot more. I would like to meet you face to face so that I could explain things a little better in depth.

 

[rick09_99]

Oh, and by the way, the check engine light is not on.

wrenchin2 what could you do to a 2000 225 evinrude to make it faster im running about 76 right now but i dont think my boat is set up right

 

[rick09_99]

Wrenchin, I think you are right about it being a 200. I bought the powerhead from Jaco Marine in Lawrenceburg. They had it advertised as a new 3.3L 'Rude Ram powerhead. That should be the 225 H.O. powerhead, should it not?

 

[wrechin2]

I just looked at my sleeve book and they offered both the 3.0L and 3.3L for those HP in the 2000-up applications. Who knows what you have. We will just see if we can identify what you have or what is wrong.

 

[rick09_99]

When is good for you? I can come right now if you're not too busy today.

 

[rick09_99]

Wrenchin, I took my boat back to the dealership that installed the powerhead, not where I bought it. They looked it up and said that it was a 3.3L 200 H.P. They are trying to tell me that the 200, 225, and 250 are all the same powerhead, only the computer is different. I don't believe them. I told them what you said about the size of the ports being different and they said no. But if that was the case, then my engine would be right because all the stuff from my 225 H.O. is on there! The part # on the powerhead is 484465 if this helps.

 

[wrechin2]

ON SOME years they are the same but on some years they are different. Here is the information I have. You can see some years they are the same. I am simply going by what the applications are for REPLACEMENT engines and the sleeves. If the porting is different, it will effect how much power it can make. I just ported a 90 Johnson to a 115 and it took raising the exhaust ports .120. If it was the same power head, then it would still run 76 MPH.

If you can't read them, Here they are in PDF

There are quite a few of them making 300++ on 93 octane. They are very touchy engines especially with the non-ratcheting gear cases. Getting a boat set of correctly is a LOT cheaper than trying to add more power.</p>

Here is a 450+ 3.3 on the dyno.

[rick09_99]

So basically, everything is pretty much the same except the sleeves? So in order to make my engine 225 H.P. H.O. again, I would have to do a complete rebuild and change the sleeves? Am I understanding that correctly?

 

[rick09_99]

Or at least port the sleeves that I have. I said exactly the same thing that you did about if the powerhead is the same, why am I not running 76 mph at 5600 Rpms instead of 60mph. They tried to tell me something about on injector not firing or some crap. I'm going to keep trying to find out as much as I can and try to get it to you on day next week as soon as you can get to it and let you run that program on it.

 

[rick09_99]

Oh, and I almost forgot, they said they thought there was a program upgrade for my engine, but he could'nt find it.

 

[rick09_99]

i don't know what i meant when I said port the sleeves! lol

 

[wrechin2]

The program I have will allow me to check the balance of the injectors by killing each injector and seeing if it has a effect on the engine. I had to replace a injector on the ficht I just built because of flooding.

These people designed the sytem. They have engine calibration disk available.

</p>

The porting can be changed without replacing them because they need raised. If they are low ports. It will kill some top end power. I know a LITTLE about porting...LOL!

[rick09_99]

So since that is a 200 hp powerhead, the only way that I can get it back to a 225 H.O. is do a complete rebuild and change sleeves, correct?

 

[rick09_99]

sorry, my posts are kinda overlapping yours. lol. I guess bottom line of what i'm trying to get to is... What exactly am I looking at to get me back to where I need to be, A 225 H.O.?
