    Continued fuel problems

    So I've posted a bunch of times about my carb problems and with no luck fixing all my latest fuel issues I received a "professionally" rebuild carburetor for my boat. My old carb number was 17057132. What they gave me in return is pretty much the same as I turned in only they ground the serial...

    Hinge pin...

    So I've removed these before on other boats, I have the pin tool, used heat and all that fun stuff - never any problems. Now I'm working on a boat (Alpha 1, 5.7L) that was wet slipped... in saltwater..... :facepalm: It also hasn't been greased in probably 10 years so the bell housing won't...

    Alternatives to my particular 3.7l Carb

    I wasn't having good luck in my last post so I figured I'd ask this particular question in a new one - does anyone know if there is any alternative to using a Rochester #17057132? It's mounted on my Mercruiser 470 (1978), but they seem like they're a rare carb and anyone near me doesn't have one...

    Merc 470 - fuel or spark issue?

    Between replacing floors and the trailer, etc. its been over a year since I've been on the water. The last time I went out-a year ago-I was running WOT for a few minutes before the engine started to shutter, pop and slow itself down - I immediately reduced speed and all was well. So last night...

    Fuel never stays in my carburetor

    So I've got this ongoing problem where my carburetor bowl keeps turning up dry every time I go to start the boat and it's getting a bit irritating having to use an inline bulb to prime every time. It won't even last a few days without the bowl mysteriously going empty. So, aside from the obvious...

    Swapping trailer axle?

    Hey guys, well my current trailer for my 18' boat is toast. It is a steel trailer from 1978 and was well on it's way to being rotten when I got it years ago. After a few years of dipping it in saltwater, It's finally to the point that the CM's have cracked right down the middle and the only...

    Trying to figure out what drive I have

    Got a new old boat and need to do some repairs and overhauls on er. I removed the drive, opened the top cover and the oil is nasty blackish color with spots of water here and there. There's nothing rusted so I guess that's a good thing. Nonetheless, I know it's an Alpha drive, but not sure of...

    '86 dc250

    So I ended up getting a Larson DC250. I have a few questions about it, and have manuals for stove, fridge, etc - anyone have a manual for the boat itself? It's an 86 aft cabin - did a search on google and got no results. Thanks for any help or guidance.

    Am I paying too much? - Larson DC250

    I'm going to look at an 1986 Larson 25' DC250 with double cabin. The 5.7 350 engine isn't running, says it needs a flywheel (i know, engine removal ahead), Alpha 1 drive needs some tlc, interior is not bad, but the hatches on the deck are ply, thought they were sold with fiberglass hatches...

    84 Wellcraft...?

    I'm not sure this post should be in this category, but I figured I'd start here. Here's the deal - I'm looking at this 84 Wellcraft bowrider to buy. It has a 350 Merc, and an outdrive I'm not really familiar with - It doesn't look like the usual Alpha I'm used to. I have a 78' Century currently...

    Mercruiser 470 3-wire alternator wiring question

    Mercruiser 470 (Converted to a 1-wire alternator from a Merc 165 6-Cyl) I did a search and found minimal results on this topic so I figured I'd see what advice is out there from folks who've done this already. My current alternator is questionable - it has recently been putting out low voltage...

    470 alternator conversion wiring question

    Well, after a few years of problem free charging- something finally went bad with my 470's notorious charging system. I've got 0 volts coming from either yellow wire so I'm not sure if its the VR or something else. Nonetheless, 3 bolts, 1 bracket, few nuts-washers, belt & a single wire marine...

    Pre-Alpha steering

    I'm sure this topic has been hacked to pieces but I can't seem to find the same scenario that I have and I'm really not sure which direction to go in... I have an old "470" outdrive, the gimbal ring has no adjustment bolts and my steering is awful-really frustrating (boat is from '78). When...

    Need some ply floor advice

    Hey guys, I'm looking for some advice on what I should do about my plywood floor. I am going to replace my existing rotting plywood floor with some marine plywood. After that, I'd like to coat the floor with something that will make it waterproof and be durable so if I drop my anchor on the...

    Merc 470 carb

    Hey guys, been a long time since I posted. My '79 Merc 470 has Rochester 2gc carb on it- the number on it is 17057132 086. My question is, what does this cross reference to auto wise? All I need is a new float, needle and seat! Would seem like a lot of money to buy a whole rebuilt kit just...

    Is it possible and effective to measure the gap between the drive gear and driven gear in order to determine what shims are needed if I don't have the shimming tool?

    Drive noise / clank

    Mercruiser 470 engine / merc 470 outdrive When this was first noticed: I was at the lake and started to notice that my drive wouldn't come out of gear easily like my interrupter switch wasn't working. Started on my way home and decided to go WOT around the lake a few times and all of a sudden...

    Outdrive swap question

    My merc 470 drive is kind of clunking while in gear at idle, seems to go away when rpms increase. This was while trying to adjust my shift cables and I was unsuccessful so I'm not sure if this happens in forward - only could get reverse. Nonetheless, it never made any noise before so I'm fearing...

    Throttle / remote shift cables

    I'm not sure if this thread will get moved or what not but - my question is with my Merc 470 - I have to replace my throttle cable and remote shift cable. It was getting very hard to move the throttle lever, and eventually getting hard to shift (yep, replaced the lower shift cable). I can't...

    What is this part!?

    Mercruiser 470 engine & 470 drive; 1978. I found this aluminum piece laying in the bilge area yesterday that has obvious crack marks on the ends showing that it cracked off of something. From pictures it looks like the bottom portion of my transom assembly; am I doomed if I don't fix it this...
