    Rebuild or replace pt2 - carburetor

    Pulled the carb for a good clean today. I think it's a Rochester Quadrajet, numbers are 32747, and judging by the paint on the bolts it's been on the engine and untouched since 1992. I was thinking of getting a rebuild kit and give the carb some ultrasonic cleaning but perhaps a better route is...

    Rebuild or replace - raw water pump

    So I pulled my raw water pump (apparently neither Searay nor Mercruiser have even remotely considered serviceability...) and it looks a little worse for wear. Since I'm missing chunks of metal from the housing, should I replace it or can the broken part be found as a spare? And what pump is...

    Remove shift/throttle linkage

    I'm about to pull the right side valve cover on my 1992 5,7 as I have an oil leak that I think is coming from the cover. By the looks of it the cover should come off if I remove the shifter/throttle linkage unit (whatever it's called...) that is bolted to the right side elbow. Now to the...

    Outdrive - where does it draw water?

    Having read thru the manual I still don't get it... I have a 1992 Merc 5,7 with Alpha One gen2 and a full closed cooling system. I'm trying to figure out wether the raw water pump feed both the engine and the outdrive with water OR if the raw water pump feeds the engine only and that the pump...

    Making the most of my 5,7

    I have a 1992 Merc 5,7 with a 2-barrel carb and Thunderbolt ignition. I well satisfied with the hp output and I'm not really looking for more. What I however would like to do is make my engine perform as good as it possibly can. What can be tweaked and tuned in order to get perhaps higher...

    Raw water intake valve - try to operate or not?

    Hi. I have a 1992 Merc 5,7 in my 1976 Sea Ray 220. I've had a leak somewhere, been taking in sea water but only (or perhaps mostly is a better word) when running the boat. Yesterday, it's been getting worse, I found that there is a little hole in the hose between the raw water pump and oil...

    Noise - normal or not?

    I have a noise coming from my new to me boat with 1992 Merc 5,7 and Alpha One gen 2. I'm new to this whole outdrive thing so I'm not sure if it's normal or not. The sound/noise is a little like that from a worn CV-joint or a timing chain tensioner failing. It's not a grinding noise and it's...

    Prop identification

    Hi. This is the prop on my new to me Sea Ray 220 SRV with 5,7 and Bravo One. I was wondering if someone could help me identify the prop. There are no markings or labels other than the numbers shown in the pics. I believe it to be a Mercury High Five, after browsing the web, but I'm not sure...

    Engine and outdrive identification

    Hi. I've just bought my first american daycruiser, a 1976 Searay 220 cuddy cabin. Supposedly the engine and outdrive (Merc 5,7 and Alpha One gen II) is 1992 and I was hoping to get this confirmed by you. How do I determine the gearing of the outdrive? I will run the boat pretty much as is...

    Questions regarding 1979 Crestliner 2455

    Hello. This is my first post here and should all go well it's the first of many. I looked at a 1979 2455 today (on land) and it's in good enough condition to take for a test ride tomorrow. If all goes well I'll buy it. It's in a used but well maintained and unrestored condition and the only...
