    1985 Mercruiser 5.7 liter, alpha 1. The engine runs great, and runs right at 140 degrees, and if I'm running at cruising speed, bring it off a plane, and idle for a bit, the engine stays cool when I turn it off. But, and here is my question.. if I'm runing at cruising speed, bring if off a...

    odd problem

    Hey Everyone, 24' bowrider with a gen 1 alpha 1, 260hp Mercruiser, 4bbl. I typically cruise around 25mph. Oddly, sometimes it takes the engine 3500 rpms to reach that speed and sometimes I get it at 3000 rpms. Same weight in the boat. Boat is trimmed the same in both situations... and same...

    Marine Stereo systems

    Hey everyone, I've been shopping around for a marine stereo system for a while now and I wanted to get some opinions. I've found some real cheap stereos, but they are only like 25watts x 4 (100 watts). I don't care to play my stereo so loud that everyone on the water hears it, but I don't know...

    prop diameter. Need prop advise for a 24' boat

    I can use a prop calculator to show the probable differences in performance between different pitched props. But what about diameter? How much difference is there between a 14", 14 1/2" and 15" diameter prop? My boat is 24' long and weighs about 4000 pounds unloaded (1996 Four Winns 240...

    Tilt/trim is very slow

    Mercruiser Alpha 1, gen I (tilt trim has the plastic resovoir beneath it). It's really slow. It does raise and lower the outdrive, but doesn't do it nearly as fast as on my other boat. And it's kinda quiet too. Now, this boat is my project boat and the tilt/trim went unused for probably 5...

    timing tab has no marks (photo attached)

    My timing tab has no marks on it. Can anyone tell me where 8 degrees BTDC is? 260hp Mercruiser V8 Alpha 1 (1985) I thought I'd read that each indentation is 2 degrees, but that would mean that my tab only goes to like 6 degrees. Or is it that every point, whether pointing in or pointing out...

    Starting issues - what else could it be?

    5.7 liter mercruiser, alpha 1 gen 1. (1985 260hp) Remanufactured engine with less than 100 hours on it. Engine runs perfectly (when started). My problem is that the starter really drags, especially if the engine has been run and is warmed up. Engine turns freely by hand (well, I didn't have...

    Oil coming out of prop end of outdrive

    Mercruiser Alpha One, Gen 1. The boat is stored in my garage. I was in the garage this moring and saw a few drops of oil underneath my outdrive. I'd changed my impellor a few months ago, so the 1st place I checked was at the screw hole.. and that was dry. The outdrive was down, but not...

    Dear Abby joke

    Dear Abby, I've never written to you before, but I really need your advice. I have suspected for some time now that my wife has been cheating on me. The usual signs are phone rings, but if I answer, the caller hangs up. My wife has been going out with "the girls" a lot recently, although...

    Trouble separating Alpha 1

    Hey everyone, I'm trying to split my Alpha 1 (gen 1) outdrive so that I can change my impellor and I'm having a hard time getting it to come apart. I've undone the allen wrench bolt, 2 nuts on the bottom, 2 nuts on the top, and the 1 nut at the front (closest to the transom by the shift shaft)...

    How many blowers does your boat have?

    My boat has one blower. The blower hose goes from the bottom of the bilge to the blower, then to another hose that blows out of the vent. I have another working blower and some extra blower hose just sitting around my garage. Would it be wise of me to install the extra blower into my bilge...

    filter on fuel pump?

    On my 1991, 3.0 liter mercruiser, I was looking at part # GLM77115 on ebasic power -- says this is the replacement fuel pump that I need. It says in the description that it is a new style Carter Pump with the filter on the bottom of the pump. I had no idea that there was a fuel filter in the...

    engine alignment (left/right)

    Hey everyone, 260hp Mercruiser, Alpha 1, gen I. I put the engine from the donor boat into my project boat and maybe it's an illusion, but I swear the engine is a little bit crooked. It seems like the front of the engine is closer to the starboard side of the boat than the port side (not much...
