Simple things first...

Make sure that the vent to your fuel tank is open - run a length of 400 lb. mono (or weedwacker mono) down the vent hole into the tank and work it back and forth a bunch of...

I am surprised that you do not have a separate and distinct vent in your fuel tank. I was under the impression that it is a requirement for all gas-powered boats with internal fuel tanks in the US,...

The oyster silver paint code is NH-282-M

The key is to put 3 coats of clearcoat on after the paint job. Procedure is:

Sand and prime cover with two coats of primer.

Paint it with Honda...

Describe exactly how you were testing the ground.

As a first step, if you have a battery selector switch, rotate the switch a bunch of times. Those contacts in the switch will corrode, especially...

Not sure on your particular boat. However, 9 times out of 10 it will be your sending unit in the tank.

There should be an access hatch on your deck. Typically, it's a 6" round pop-out hatch. Open...

There are several online sites that will help you find the proper pitch and diameter prop for your boat. Start with the Grady White website and Grady White forums and see what owners with similar...

Just to give you a comparison, I'm pushing a 25 ft. C-Hawk which weighs up to 6,000 lbs. when fully loaded with fuel, lots of fishing gear, and two adults. I'll get ~5800 rpms on a 14.5"(diameter) X...

That looks pretty extensive. I assume they flushed and treated the water passages in the heads, though nothing said about that.

So, the 5 items in my list are still relevant.

I'm no expert on rebuilds, by any means. But other items that may be affected are:

1. Water passages in the cylinder heads (if not replaced)
2. Thermostat seats in the heads (if heads not...

Sorry to hear you are having so many problems with these engines. Usually, they are very reliable.

However, only 450 hours on 17-year-old engines tells you something. They likely spent a lot of...

Well, it all depends on how extensive the corrosion was and what they did on the rebuild. However, once the block is damaged, I think it's hard to completely recover it without replacement. Just my...

That doesn't look good at all. I'm not sure even JB Weld can give you much of a fix. Probably time to re-power. It will be difficult to ever trust that engine again, IMO.

I don't know for sure what would cause that. If I were in your place, I would change out the entire water pump this time. In the process, check the mid-shaft bushing for looseness or deformation....

The links to the pictures are not working.

As for the HO2 sensor. You may want to check the connector and see if you get 12 volts across the black and green wires when the key switch is on. If not, check your fuses - especially #5. Note that...

What year is the engine, or what are the first 5 numbers in the serial number?

Battery light will stay on until engine is running. The green oil pressure light should come on when the engine is...

Congrats on your recent purchase. The BF 225 is a GREAT engine, IF WELL MAINTAINED AND RUN OFTEN! I have a 2007 BF225 with over 2200 hours and it still runs great. The USCG regularly puts 5000 to...

Yep - that's the only fault that gives a rapid alarm.

If you have an external fuel/water separator (which you should have - i.e. like a Racor 10 micron) you should also change that filter. Then...

# 2 is out of spec, obviously.

What did the plugs look like when you pulled them for the compression test? If firing correctly, they should have all had a light chocolate brown coating. Was the #2...

Did you ever fix this problem? If so, what was it?
