Ok. To close out this issue... the brand new Sierra mechanical fuel pump was shot after a couple hours of running. In the process of trying to start the motor, I fried the starter solenoid and possibly the battery too. Either way, I replace the solenoid with the spare, new fuel pump, checked the ant...

I have a Sierra screw on style fuel filter. The Perko has been removed just to rule that out. Thanks for the suggestions from everyone. I finished off my already dying starter in this process, so it’s getting rebuilt / replaced now. I’ll try some of the recommendations next week.

Thanks for the feedback. The brand new fuel pump was tested and it’s definitely bad after 3 hours of use. With the new fuel pump, I’m wondering if running the carb dry and also replacing f the fuel / water filter (and having that dry) is too much air for the pump to overcome to achieve a good prime....

Definitely not a shutoff, but the pump may be installed wrong.

I am most definitely stumped. Here are the facts: The anti-siphon check valve is good and working properly. I am able to easily manually pull fuel from suction hose just before it goes into the fuel pump. I have no fuel being delivered past the fuel pump. The final fuel canister filter was replaced ...

I realize that no oil consumption is normal. My Stbd 318 consumed about 1.5 quarts after 12 hours of running. I know the previous owner only ran this boat twice a year at most and that was at 2000 rpm or less. What’s the worst case / best case for this motor? I plan to check compression soon, but I’...

Does anyone have a photo of what the anti siphon / check valve looks like? It seems they have a history of being problematic, but I’m not sure which part of the fuel system this is.

I’d be interested in the plastic tracks if the aluminum ones are nowhere to be found. I’m not sure if Mr. Althouse is still selling them. Most of those posts are from 2016 or earlier.

Perfect. I’ll track down some aluminum tracks and I’ll arrange for some polyglide too. Thanks for the help.

It looks like the poly glide that was listed on eBay is gone now. I remember reading the guy’s post a while back saying he was going to sell out and get out of that business. I don’t know how necessary the poly glide is?
