This place claims to have it in stock for $134.89 & free shipping. I would call and make sure it was in stock.

Summit Racing is the same price, but back ordered.

Thanks for all the help Table Rocker. Unfortunately those guys are closed for the weekend. I had already called Summit and the guy said I could call on Monday and they would inquire with having the manufacturer drop ship me the pump. Napa said the same thing.

Things here will be going on hold for the weekend since nobody is open or available to contact the manufacturer.

I am going to call Napa and Summit first thing monday and have them call the manufacturer to see what the est delivery time is. Hopefully quickly.

Yesterday I swapped the oil pressure sending unit and the relay for the fuel pump. Pretty sure the oil pressure unit fixed things. Ran it full bore for about 25 minutes and no issues. Indicated good pressure on the gauge the whole time rather than the needle bouncing all over the gauge. It showed 15psi at idle, 40psi at idle to 3500rpm. 65psi up to redline.

Ran like a raped ape like it used to the first few times I went out.I'm a happy boater! I will still order a fuel pump and swap it out shortly here knowing how they fail.Thanks for all the help and support with this one!

wow, can't imagine how relieved you must of felt having it run normal again. With your documentation, this thread is likely to be a big help to others in the future. I'm sure the weekend can't come soon enough so you can actually enjoy the boat.

I'm glad you are back on the water and I'm glad it turned out to be a cheap fix.

How about JerseyDave spotting the issue in the video and making the diagnosis in post #147? Well done JD!

I have bookmarked this thread seeing as I have a 1996 version of the same boat. My biggest problem is a vapor lock every now and then...but then again in the depths of south Alabama it seems to get a little warm in the summer. Good luck.

I am hoping this thread can provide info to many people to come. I plan to continue to add to it as well.

I agree that jersey Dave spotted it back in the thread. I have read conflicting evidence that the oil pressure switch can actually shut the pump down and it sounded like he wasn't 100% sure, so I had that further down my to do list. Looks to me like it in fact MEFI can shut down the pump if it senses a "loss" of oil pressure. Good stuff to know!

I am relieved that it's good to go now. Should have done that sensor 5 weeks ago, but I know the inner workings of this beast much better than I did. To me that was worth the slight headache that this has caused me. I've got the mastercraft lt1 service manual and it was helpful in the diagnosis as well. I am going to read some more on that shortly and get a few questions answered through it.

Thanks again for the help folks!

That is fantastic news that you have it figured out. This has undoubtedly caused you a lot of grief and hair pulling. Again, that's great that you are back up and running
