I purchased my Parker about 6 weeks ago. Several weeks into running it, I noticed the Yamaha OB started bogging down at higher RPM's. This preceded to get worse over a couple of weeks until it would barely stay running at idle.
This being my first OB, I immediately started reading all the related posts here on CP, and spoke to the mechanic at my marina. First thing I did was start with the easy items. Replaced the Sierra Brand Fuel/Water filter with a Yamaha 10 Micron filter. Also replaced the fuel/water filter on the side of the motor. No change in running, it continued to bog.
Next thing, after reading many of the same posts multiple times, I decided to try my hand at cleaning the VST filter. Got to it fairly easy and found it to be almost completely clogged. This thing looked horrible. I tried cleaning it, soaking it in carb cleaner and blowing it out with an air compressor. It cleaned up very little and I decided to bite the bullet and buy a new one and the gasket for the tank as well. I cleaned the tank out and the float as well. In the pictures, you can see some type of film stuck to the float. It cleaned up very well.
Put everything back, dropped it in the water and it ran the best it has since I've had it. Not the first issue with power loss or bogging down at all. Seemed like I had an entirely different OB on the boat.
I'm posting this and the pictures of the process as a Thank You to CP and those posters who helped me with their previous posts. Hopefully this may help someone else in the future with a similar issue. Having cleaned the tank and replaced the VST filter now, it doesn't seem like that big a deal and was not difficult at all to do. I'll definitely be keeping this one clean on a regular schedule. Also learned some things about the 3 low pressure mechanical fuel pumps for whenever they need replacing in the future.
Anyone have suggestions on other items that I should be proactive in cleaning/replacing before things start to go bad again? I believe in performing regular maintenance before the small things being neglected cause major problems/issues.
Thanks again for your posts and reasonably priced training.
