My boat is still semi bogging even after I adjusted my raves out to the proper adjustment. Not sure where to go now. Carbs were just rebuilt last fall. This is just after normal driving after about a tank of gas. 1st is pto 2nd is mag.

They look pretty good but I'm confused a bit by the rusty, brown look. What kind of oil are you using?

Did the engine recently have water in it?
 
I'm running XPS fully synthetic. I was just having you guys look at them because I was having issues with it bogging at 5k. I thought it was because my raves were adjusted all the way down by the previous owner. After adjustment it fixed 95% of my problem, but still does it. I heard it could be because it was lean so I just wanted a second opinion on the plugs so to make sure it wasn't going to ruin my engine running it all day Thursday. I also noticed from about 4k to 6k there really isn't no In between. You're either at 4k or 6-7k.

Not sure what was replaced in the carb rebuild, I just got told and backed up with reciepts that the carbs were rebuilt.

When I did my top end rebuild I did have to remove the carbs at the gasket to tighten the manifold down. I replaced the gasket but didn't put any gasket adhesive down. Could that be causing the bogging issue?

Also I just installed a second battery to help run my audio system I just installed. I can't believe how fast the thing starts now! It is litterally instant. It used to take 7-10 seconds of cranking when cold to start. Now I dont even hear the starter because it starts so fast, didn't even have to choke it when cold!
 
Not sure if the engine had water in it. Maybe a little when I pulled the jugs. I sucked what I could out and felt confident I had it all.

This is my third tank of gas since the rebuild. Oil tank has went down about 3 or 4 inches. I have switched to these plugs in the third tank which had little to no extra oil added to the fuel. It does smoke quite a bit at wot but I attribute that to being normal but this is the only 2 stroke boat I own (or any boat for that matter) so any help is appreciate.

Also in the first pic I showed the lightest spot. Other than that one spot the rest is a darker color like the second plug.
 
You can test for a leak at the mainifold to double check but if you installed the gaskets correctly you should be ok. If you have dual carbs are they synced and the carb High and Low screws set correctly? You check the pop off also if you have a tester.
 
Is there any how tos on checking the sync of the carbs? Also is it possible to adjust the high and low speed screws with the air box on?

I don't have a pop off tester.
 
I just did the 15 min wot then pulled the lanyard and looked at the plugs. I have a feeling I found my progressively worse bog issue. How do I go about fixing this before it causes problems?? Thanks.

plugs look good now, but looks like a bigger gap then normal, and where are your raves at ??? the adjustment cap ??? gap plugs maybe ?? put raves just a little in from flush and try
 
The gap is at like .024

Raves are flush. When they are turned in slightly it has trouble getting over 5k (it still is now). Really is frustrating trying to figure this out.
 
are the hoses to the raves good and the bellows ??? maybe you have a leak ??? is the rave solenoid working ??? also check the hose to the motor for leaks

cause when you backed them out and it got better, what you did is loosen springtension, and if it got better ??? then i would verify that no leaks in system

This is what one of my raves looks like underneath the cap. Would this little bit of oil be the cause of it bogging like no other and being next to impossible to get over 5k? The line from the carb to the block looks brand new.

mine are dry where yours has oil, something isnt right there ....

im not gonna say thats that the problem, but if you adjusted em and it seemed to get better, your on the right track
 
Yeah it was better for about An hour. Then the problem came back just as bad as before.

The other rave is dry. I just wasn't going to replace any of that until I knew it was the problem.
 
does it ever backfire ??? or miss real bad, like the rotary valve is out of time ???? the one rave valve in my opinion is pretty much on borrowed time, i believe if you take it all apart you find it egg shaped, and when this happens, (people say) the valve will chatter and break and hit the piston, so that valve and housing should be changed, as long as the carbs are good and synched and adjusted as i read in this post, i might check the rotary valve for excess play also, it doesnt really cost anything to take it aprt and check it out, i can get to mine in about 30-40 minutes.
 
If the valve is out of time would it cause it to bog at 5k?

The raves were clearanced when I rebuilt my top end and full bore reman said they looked fine.
 
sounds more like carbs to me, but, the clearance may be ok, but the shaft and the housing is where the problem exists with the raves, also, if you have already ran 3 tanks of fuel, then the oil injection may me just the right amount of oil for you then, recheck the adjustment on the pump, excess oil makes plugs foul, misadjusted carbs, makes bogging problems, and lean problems, this in turn creates piston problems from bieng too lean, what was the problem you had that caused the top end to fail ????
 
I switched oils in a bind and clogged the oil filter.. I completely flushed the lines and tank as well as changed the filter. It is getting the proper oil and the adjustment is right on the pump. It's like you have to work it up to speed to get it to go over 5. Once it hits five you have to back off and punch it multiple times to get it up and going. I really thought the plugs looked lean. Do they look right to you?
 
a little lean, but thats why people are asking about the carbs in synch and adjusted, also too much oil will lean these out as well, you have to have a proper fuel/air/oil ratio, as of right now, by what u are saying, u are using more oil than needed -- and compression should also be at least 150 in 787, if not 160-165,
 
Yes every hose has been replaced including the small oil ones from the pump and all the fuel and carb lines. If my high and low speed screws were not adjusted right could it cause this?

It also idles at 1500 in water and 2200 out of the water.
