Did you try a new fuel pump along with a temporary tank supplying it, to narrow things down some?

We had a similar problem with a 650 last year. Finally sent it back to them and they replaced a couple parts and sent it back to us and it has worked well since. I'd have to dig out the paperwork to remember what they did, but it was an assembly problem. They do offer great support.

Hobby Boats can be expensive when the hobbyist is limited on their own skill and expertise.

Hey Jody. This is an HO with about 560 hours. Looks like the orange cam in the #1 location. Any thoughts?

There I was, surfing around your SCM website with all these boats being restored and I couldn't help but wonder if this issue ever got straightened out and what the problem was.

Well there I was doing some more surfing and it looks like Jeff found a fix for his issue
 From his PN thread Just wanted to update this thread with regard to the bogging issue this boat was having earlier. As you'll recall, I had purchased and installed a brand new Quick Fuel M-600, which has a great reputation as a perfect carburetor for this engine. Unfortunately mine never worked properly. We adjusted it every way possible, and no matter what we did, it would bog down and stall if you accelerated at all quickly. I finally got fed up with this Quick Fuel and had the original Holley 4160 rebuilt. We popped that back on the engine, and it runs PERFECTLY now. Clearly the Quick Fuel has something wrong with it internally. I'm going to contact them tomorrow, but I bought the carb about ten months ago now, so I am sure they won't take a return. Maybe they'll offer to repair it for me or something. We'll see... |
