    You're probably right. Only other time I saw this type of metal erosion was on a Yamaha FX140 that sank during Sandy and was left sitting with water in the motor.

    I'm guessing the spark plug was...

    I don't have any other parts from the motor. I only bought the head. It was described as "used" with no mention of the damage or repaired hole.

    The price was right. But I'd rather pay more for...

    Thought about a thread chaser or a tap, but I don't want to risk damaging the existing threads. I don't want to do anything that might preclude returning this head to the seller. If I can't clean...

    I've seen quite a few of these that were heavily corroded. Of course, proper maintenance is the key to making anything last. But I think the issue is that this exhaust system requires more than...

    Took a closer look. The threaded insert appears to be the correct one and is installed properly. The apparent problem is that the motor was run with the spark plug not fully tightened down. This...

    I got the head without plugs. To rule out a problem with the plug itself, I tried 2 different plugs in the hole with the same result.

    Ultra 310 Cylinder Head

    Don't know the history of this head, but obviously the spark plug hole has been repaired with a threaded insert. The spark plug cannot be installed all the way, and ends up about 1/4-inch higher...

    After 4 years of aggravation, I think I'd just sell the replacement and buy something else.

    Remove the boots from the spark plug wires. Trim the wires back about a half inch. Then re-install the boots.

    Ad didn't say it was not running.

    Too late now, but you should have left the DI fuel tank. I did a conversion last year in which I used the top section of the DI fuel pump and attached pickup/return hoses to the two metal tubes on...

    Thumbs-up for Darrin's service. Referred a friend to him over a year ago. Turnaround was quick and the EMM still works perfectly.

    Never had the issue with a Kawasaki, but the Yamaha MR1 motor behaves that way when one plug goes bad. Top RPMs drop from 10K to 8K, but it runs fine otherwise.

    There are so many known problems with the Ultra 250/260 Jetskis. Investing $3K might be a big mistake, especially since it never ran right since you got it. Until it's repaired, you won't know if...

    If you don't mind the drive to Long Island NY, there's a guy out east with acres of property covered with hulls and parts. I'll bet you can pick one up from him.
