    Update on rebuild and shifting

    Well, finished the rebuild of my Dad's 2.5 liter Mercruiser. After a brief panic attack when all we could get was backfiring instead of starting, (I was just sure I had installed the cam wrong - it's amazing how small the mark is on the cam gear! :eek: ), I tried turning the distributor 180...

    adjusting lifters on 2.5 Mercruiser

    This is my first time rebuilding an inline 4. I have rebuilt quite a few small block Chevies however, and I want to make sure I am adjusting the lifters correctly. Are they adjusted like small blocks? (Take out the slack in the push rods and turn another half to three quarters of a turn? I know...

    Let the buyer beware (Never assume!)

    As I mentioned in my other recent posts - I am helping my Dad with his Mercruiser motor. I am rebuilding it. He bought this "new" motor about 8 or 9 years ago from a local shop. He had a 3.0 liter in his sportcraft that they replaced with another 3.0 liter... or so they said.<br /><br />Upon...

    Mercruiser Control Box

    I am helping my dad with his boat - he has a 1986 19' Sportcraft with a 3 liter Mercruiser and Alpha One. The Shifter control box is in need of replacement. (It is very loose and sloppy - basically worn out). Does anyone know if you can use any of the aftermarket brands available? (This is...

    How much play is too much? (Alpha one)

    Sorry for the long post, bear with me! :( <br /><br />I am still having problems with adjusting the forward and reverse on my 1986 alpha one. When I take the drive off, I can turn the shift "shoe" on the outdrive and make it engage forward and reverse very easily (turning the prop by hand in...

    Time for a new shift cable?

    First, some background: I am working on my father's boat - an 86 Sportcraft with a 140 engine an Alpha One outdrive. I finally got it running,(new points and condensor, started right up :) ), but while on the motor flush I tried putting it into forward and reverse. Forward went fine...

    Help removing zinc from Alpha one

    I need to replace the trim tab zinc on my 1988 Mercruiser Alpha One. The bolt holding it in is supposed to be a 3/8" allen bolt which you get at from the top. My bolt is apparently stripped. There is quite a bit of corrosion and debris in the cavity where you access the bolt head. After...

    How can I tell the pitch of my prop?

    I did a search of the archives for the answer to this question. Some said it should be marked on the prop.... I looked on mine and couldn't find anything that seemed to designate the diameter and pitch. The diameter I can figure out, but the pitch? How do you go about finding out what the...

    I have an 1988 boat, (Sportcraft, originally came with a 5.0 liter engine), and I am putting in a new 5.7 liter crate engine from Mercruiser.

    Running engine without stern drive attached?

    I am installing a new 5.7 liter Mercruiser engine in my boat. It has a 1988 first gen Alpha 1 outdrive. I am bypassing the water pump in the outdrive with an 1.25" thru hull fitting and engine mounted raw water pump. I have the engine installed now, but not the stern drive yet. It is okay to...

    How to tell if the gas is bad?

    This boat I just bought has been sitting up for about a year. It has a 118 gallon fuel tank. I had assumed it would be about empty, and was planning on simply removing the old gas and putting in fresh. Well, lo and behold, I removed the sender and it is full to the brim! About a hundred...

    Help with stuck (stiff) Mercruiser Alpha 1

    I recently purchased a 1988 24" Sportcraft Walkaround (242 Offshore). It came with a 5 liter Mercruiser motor and Alpha 1 (first gen) outdrive. It had been sitting up for a year when I purchased it and several things were "frozen up" on it. I freed up the steering cable so that it moves...
