To follow up on this problem (in case 50 years from now someone is restoring one of these), my friend took it to a dealer, and the problem was, as a couple of you suggested, the high pressure fuel filter. The dealer changed both filters, and briefly told him how to find and change the high pressure filter. A couple big parts have to come off, including the long intake manifold that stretched across the starboard side of the powerhead before you can even see the part. He was told that filters are about the only problem they ever see with that model.

They charged him for 3/4 hour of labor.

Thanks again for all the suggestions – I probably could have fixed it last week on our fishing trip if I had metric tools along, but then maybe I’d have dropped parts in the lake, and it’s hard enough sometimes to find parts dropped on my workshop floor!…..and I would have been learning on someone else’s nearly new motor.

I hear ya Dave, am always hesitant to mess with a piece of equipment I’m not familiar with, especially someone’s new and expensive equipment… Would have never figured you had to remove the intake manifold to get at a filter, but I guess that is fairly normal these days….
I wouldn’t have monkeyed with it either, unless I knew exactly how to get at the filter beforehand. And like you say, would probably want the boat out of the water… Sometimes, I think that water is magnetic, so powerful that it even attracts stainless pieces…

It’s pretty standard practice for an EFI intake runner to cover important fuel system parts. Some are easier to take off than others. You might consider this a pain in the butt; but compared to four stroke carbs, EFI is usually WAY easier to service. Unless it’s a small motor, I won’t even touch four stroke carbs any more.
