The surging only happens over 4200 rpm's. The water separator has been changed and there has been zero water in the engine mounted separator. Fuel has been ran almost completely out and topped off with new. Bad fuel doesn't make an engine run rich. All filters have been changed and the...

I'm not trying to get him to tell me how to fix the issue. I want to know: 1) I'm going to do "X" to determine if you have sufficient fuel flow. 2) I'm going to do "X" to determine if your thermostats are letting the engine get hot enough. 3) I'm going to do "X" to determine if your O2 is bad...

Some of you might have seen some posts on our '99 225 issues. We have resolved stalling, rough running, but have yet to crack high rpm surging and running rich. There is only one 5 star yamaha tech near our home in Ohio, but it is still an hour drive each way. This also happens to be the new...

I know what a plug should look like from a 4-stroke, but rarely have I seen a nice tan plug out of a 2-stroke. Should I expect a tan plug (void of carbon or oil) from a properly running OX66? Grady 28, How many hours do you put on in a year? I wondered why you replace plugs annually. Unless...

For those of you that are confident your engine is running properly, what do your plugs look like when you pull them? My '99 225's are translucent black and wet, but not fouled. After reading Sal's post on the o2 sensor, I'm wondering if this could be an issue for me. If what I have is not...

Sal, Would you say the engine was surging over 4k rpm? We are still chasing an issue on our '99 225 OX66. Idle, rough mid-range, and starting stalling have been fixed, but over 4200 the engine surges. At 4200, the engine runs up to 4800, then 5k, and back. Fuel consumption seems high too...

I can't say for sure, but I would guess the majority of roll-over stories you have read 1st started with some type of fitting failure below the water-line. I have a '99 248 with a single 225 yamaha. It would take a he!! of a wave to swamp this boat. Were I live, if the waves are big enough to...

PLEASE let me know what fixes this issue... if you get it. We are having the same problem on our '99 225 and we have yet to figure it out. Thanks!

YES.

I couldn't agree more, but when material costs keep going up, and builders need profit from a smaller pool, it leaves them little choice. That coupled with stagnent wages for us working saps widens the gap even greater. I too am not happy about Beaver Park losing Grady, but I can't help but...

I have a Voyager (essentially the same boat) and I would say a diesel is overkill. I brought my boat home (Fl to Oh) with a 5.7 tundra and on many occasions I forgot the boat was behind me. Fantastic machine. Incredible power and the quietest vehicle I have EVER been in. The newer 1/2 ton...

woodworker2001, I don't know what you do or don't know, but a boat kept in water for 17 years can have all sorts of issues if not maintained. If you plan to trailer the boat and not dock it, the upkeep on the bottom paint alone is no fun. We bought our boat from Florida and brought it back to...

Salinity Now, You might want to look fuel delivery restrictions before you start playing with the TPS. As for the adjustment, it is simple. If facing the engine from the boat, the TPS is on the upper right side. A rod from the throttle linkage inserts into the TPS. Loosening the 2 TPS screws...

I thought I'd share my story after lot of bad and misleading information. Our 1999 Yamaha 225 ran rough since we got the boat last fall. Many including us suspected it was from old gas. Running the old gas out and replacing it with new did not seem to make much of a difference. After only a...

If you buy a pre VS2 hull, and then try one that is a VS2, you will wish you went with the 96... especially at the price range you are shoping in.

#1) Save everyone some work: viewtopic.php?f=2&t=16387 #2) Don't know. Grady site might be of help. #3) Depends on condition. We paid $21 for our mint '99 w/ ~ 100 hours. I think few have that little for what we found. Paying a little more for a sound machine is worth every penny. Good...

What year did they lengthen the hull to the transom?

Between 2 people, it wasn't too bad. Most of the wood was delaminated from the fiberglass anyway, so it wasn't too tough to clean up. As far as the tank goes, ours got a hole from placing pressure treated wood on top of the tank. We found out the hard way that aluminum and pressure treated...

Not certain what a 200 merc would do, but a 200 Rude would get ours up to ~48-50mph with 2 people, no hard top, ~40 gal of fuel, and no bottom paint. If you don't have tabs on it, get them. They make a world of difference on that hull!

Great work! Been there done that... on the same boat too! We used Sea Cast, which I know some people aren't crazy about, but it worked well for us; the second time. I didn't read your entire thread, but I have to tell you this just in case. When our transom went we cored it out and used the...
