    Erratic Tach readings/bad Voltage regulator?

    I've noticed when I am running distances (few or more miles) at cruising speed one of my tachometer is not reading the correct rpms, meaning, at around 3600 rpm (gauging this by my other motor and the similarities in sound) my gauge in question will read +/- 5000 rpm or so and has erratic...

    180 (470) Mercruiser fuel pump

    Greetings, My fuel pump on my starboard engine appears to have gone to its great reward. It will not even spit out a drop of fuel when I crank the engine with the fuel line stuck in a bottle. A quick question that hopefully someone has an answer to, When I change it out, other than the...

    180 (470) Mercruiser risers/exhaust manifold

    Does anybody know (roughly) what the lifespan of these are in Saltwater? I have 2 of these 1987 180 (470 seems to be what everyone calls them) mercruiser motors that as of right now are both running cool as cucumbers and showing no signs of trouble. However, reading about these engines and how...

    Has anybody ever changed the exhaust bellows for the tube type without disturbing the u joint boot and shift cable boot? I am launching on Wednesday afternoon and had one of my exhaust bellows slip off at the bell housing end (didn't tighten the clamp) and instead of fighting with cleaning off...

    Pertronix ignition in 470 and locating resistance wire

    Anybody have an idea on how to find this wire's location or if it's a plain old resistor where it might be hiding? It's a Carver boat if that helps...I'd assume it would be similar in most boats

    Alpha one steering arm access (Templated holes)

    I am having difficulty getting access to the steering arm screw and nut to loosen my gimbal ring. The screw and nut are fairly rusty and look like they will give me a had time removing them..that is if I could get a wrench or socket on them. I used the template and drilled my holes but it seems...

    Rotella T1 diesel engine oil in 470 engine

    Anybody familiar with the difference between the T1 Diesel engine oil and the T1 engine oil. The previous owner of my boat ran SAE40 Rotella T1 oil, so I went out and bought what I think is the same oil but instead of saying "engine oil" it says "diesel engine" oil. I have an old container that...

    Alpha one gimble swivel pin (lower)

    Anybody see one of these wear out? I mean I have quite a bit of slop in it and it just seems like an odd thing because the other side is fine. (comparing port to starboard) I am not talking about steering slop...Im talking the lower pin (17-99353) Also, does this pin need to be pressed out or...

    Lower unit driveshaft slop

    I'm doing my water pump on my alpha one drives. Upon disassembly I notice a slight play (vertically) when I removed all of the water pump parts.Maybe a mm or so...not much but enough for me to question. I also noticed that when I spin the driveshaft with these items removed, there appears to be...

    exhaust pipe rot?

    I bought a new to me boat last year at the end of last season. Got a really good deal on it. Put it in the water only to find out it leaked...pretty bad..bad enough to pull it out in less than a week...cost me $1000 just to move it twice that same week. Anyway, I thought I bought a lemon with...

    What's the best bottom paint for the buck?

    I gotta paint my bottom and drives before I launch this year and I was looking for some feedback on what paint to use. I'm in Saltwater,Long Island Sound. Also, How far do most of you guys go to smooth out the chips from the old paint coming off? I would think you would want the smoothest...

    Alpha One Transom removal

    Curious to see if anybody has attempted to remove a transom assembly without pulling the motor. I have a leak that I need to fix before I launch in the spring that I THINK.... might be the exhaust pipe. In order for me to fix it I need access to the bolts that attach the pipe to the transom...

    Confirming leak in transom Alpha one

    I bought a new to me boat 1987 Carver Montego 2557 double cabin. The boat runs well but I purchased it out of the water. When I put it in, it was leaking from the transom on the starbord side. Not a lot, but enough for me to pull it after a week of worrying about it sinking if the bilge failed...

    Twin screw alpha one both turn the same direction?

    I just bought a 1987 Carver Montego 27ft I am looking at my boat I notice both props are the same. Meaning, they both appear to be right hand props. I always assumed that twin screw boats have counter rotation props. Am I seeing this properly? The guy I bought the boat from says they both turn...

    Leak/unknown origin Alpha one first gen.

    Bought a new to me boat a few weeks back for a real good price. I needed to move it quickly so instead of sending it to my house and inspecting it before launching I took the chance and put it in the water. Previous owner assured me it's was good to go. Well, long story short...I am now taking...
