Did you just get this boat or something? Did you just rebuild it? You might want to check your fuel system, fuel lines, main filter, fuel valve, or internal carb filters.
RE
Had it a few years. It almost sunk last year. We put in a new battery, new plugs, new gas with seafoam to clear out any gas or dirt particles. Cleaned the oil filter, fuel filter and made sure the air filter was good. Verified there was no rubbage in the propellor. Broke it down to the carberator and didn't appear to have water or rubbage there. Can you tell me how to check the carb filters? That is where we seem to think it could be. Not sure how to check the compression but saw that on a few other posts for other issues as ours. Running Lean?????? Unsure what this might mean.

i doubt its running lean. the internal carb filters often get clogged when you have trash in your fuel or just a little trash over time.
also do you still have the grey fuel lines?
these are bad news.
in laymans terms on each of the carbs there is a circular side and a rectangular side. the filters are in the rectangular sides and you have to take the carbs all the way out to get to these filters, although it is a very simple job
look in the attachment for where these are, what they look like, and how to get to them
Hope This Helps,
Alex

Alex. If the carbs or filters are plugged then it IS lean. Timmy was just summing it up.
Do a search on compression check. I no kustomkarl has some excellant detaild posts. Even if that's not what it is its still good to no

not saying your wrong, but the filters can get clogged from trash in the gray fuel lines or bad gas in the tank. got to know that real well about a month or two ago. but im definately not saying your wrong. im just adding to what it could be.
Man....I tell you what. My 96 XP is driving me insane doing the exact same thing.
Runs like a champ on the water hose, put it in the water, and she will pull up on the water and run about 2 mile per hour
I bought another set of carbs...she ran fine for two days...not back to the same CRAP!
Well, she didnt run fine really...she would bog when you first mash the throttle, but she would jump up on the water and run like a scolded dog!
I have checked compression...145 in both. Changed out the front box and the read box with his running fine SPX...just to make sure it is not electrical.
I took the carbs apart tonight...one of the little screen baskets looked dirty, the other didnt.
I Was thinking of running a bottle to it tomorrow...see if it is just not getting gas from the tank to the carbs.
SO, what oil ratio should I run to a gallon?
Anyone close to western NC who wants to fix this thing !? :ack:

1st, here is some information on doing a compression test correctly.
compression test;
To test compression, remove both spark plugs. Place spark plug caps on the plug cap studs near the cylinder head to ground the empty caps. This completes the circuit of the ignition electrical system and prevents any electrical problems from the caps being un grounded. Using the correct adapter for the threaded end of the tester,( same length of the spark plug threads length)screw in the tester in one plug hole. Hold the throttle wide open. Push the start button. Watch the compression guage, when it peaks out at the most compression, let go the start button. Read the psi number. I would do it 3 times to be sure it is accurate. Check both cylinders the same way. The ideal compression is 150 psi per cylinder. If it is less, it's not a problem as long as they are close to being the same. If the psi is less than 90 it might need be time for a tear down and a rebuild. If the psi in 1 cylinder is say 140 psi and the other is 80 psi you need to tear down and repair. This difference is a lot then there is a problem. I hope this helps you.
2nd, If you have Gray fuel lines you need to replace them with new ones. Go to like Auto Zone and get new fuel lines. Bring a sample so you get the correct size. Replace the clamps with stainless ones too while you at it if needed. The gray fuel lines deteriorate on the inside and clog the fine screens in the carbs and clog them up. Be sure to use carb cleaner to clean all the passages in the carbs too.
If the bottom end is boggy on acceleration, check the fuel pump. Remove the air box assy. and apply the throttle not running of coarse. look to see if you get squirts of fuel in the carb throats. If not the lines or pump diaphragm might be bad.
