Thanks for the input Droid!
Never chineesium for me!! Ive been down that road replacing stuff 2-3 times. No way, I operate this boat full of friends and family, sometimes in the ocean. As a mechanic I prefer quality parts that 1.) Work like they should and 2.) Last like they should.
I just chatted with a parts tech at boats.net. He confirmed that there is no note or information listed from Mercruiser indicating a change where the pump needs to be mounted opposite of its original orientation. Also confirmed the part number 41141A2 is correct for my engine but has been...
Okay, Thank you for the fast reply. If you follow the link to the 2nd pump listed (1st is NLA) Quicksilver P/N 862077A1, it says in the comments mounted with the filter bowl facing down. I am all about buying OEM parts whenever available. Should I buy it and try to mount it like it says? Or am I...
Eng S/N 0B776858, 1988 4.3L LX. Symptom: Runs on lake at 3/4 throttle all day. When I try full throttle it tries to accelerate then falls flat. Bring back to 3/4 its happy. Starts and idles great. I have rebuilt the carburetor. I think the fuel pump is original. I want to replace it just to...
What I found is this:
TO - Tonawanda NY plant
817-Aug 17th
CKB- 350 cu.in. '72-74 year models.
the other number 12s... came up with nothing <don't mean anything. Maybe others can find it>
Are there any numbers on the other side of top rear of the block?
BinLinerCashity, There are some videos you can watch that will help you understand whats involved. Look up DIY with Michael Borders stern drive.
He has a series on a Alpha One Gen I (I think its a gen 1). Remember its for reference ONLY and make sure you use the manual procedures called out for...
Hollywood7744, Let me help you help the guys in here to be able to help you.
There should be a metal tag on the back of your engine that has your ENG SERIAL Number. That is the most important thing to post on here because without that information we cannot provide you with accurate...
First of all most of the guys in here who willingly help people are factory trained and have access to info and manuals or even places to get parts near you and a lot of information you wont get anywhere else. Some of us are a lil older and grumpy, and get weary of folks asking for help with...
Okay,
Sorry for the confusion; what I meant by starter threads are the first few threads of the hole.
The hole in the block above the oil filter is .421 <a bit bigger of course after it was tapped with threads from the manufacturer.>
Yes I am referring to Tapered Pipe Threads when NPT is...
Okay, Here is what I've found: 1/2-13 = .421, and 1/4-18 NPT = .421. That's why 1/2-13 went in so easy. Only a few threads. So I need a 1/4-18 Tap to try and clean up the starter threads. And a die to do the same to the adapter.
Hopefully I do not have to drill it up to the next size...
Got the new NPT 1/8-27. Its the size of the switch threads. I'll add it to the set of 3 I had. More research needed. Not too familiar with NPT sizes. Have full sets of SAE and Metric. Don't usually have a call for NPT much.
Well it did go in kinda way too easy. New tap will be here tonight. I will see if it will work. I dont think a heli coil will work and still be able to use NPT threaded adapter. If the hole had a bottom and not pass thru then maybe. There is a company that makes custom adapters McMaster-Carr...
