    Mercruiser gear ratios

    I have had trouble getting my engine -a 1984 140 mercruiser- to run at around 4500 rpm at wot while pushing a 19 foot islander with a 19 pitch prop. After a complete rebuild I managed to get it up from around 3000 to 3400 rpm, nowhere near the 4500 point. So I did some checking on lower unit...

    1984 rebuilt 3 liter 140 Mercruiser with EST Voyager ignition After rebuilding, this engine runs fine and smooth but still does not want to go over 3200 rpm while pushing a 1984 Starcraft Islander with a 14.5x 19 prop when it is properly trimmed out. Trying to find the problem,I discovered that...

    1984 mercruiser rebuild with ignition problems.

    Adding a bracket to a 1984 19 foot Islander.

    I'm toying with the idea of removing the 140 I/O setup and replace it with a 150 or 200 horse outboard on a bracket. Has this been done ? If so, what are the structural changes that have to be done on the inside of the transom and the rest of the boat? Having 3 or 4 hundred pounds of engine...

    What to expect from a 1987 9.9 4 stroke Yamaha?

    I've been thinking about changing out my 1979 9.9 Johnson trolling motor, not because it is bad, but because I don't like to work with a Mercruiser 4 stroke and a Johnson 2 stroke. It is just much easier to run a fuel line from the main tank compared to having to deal with a second tank in a...

    What to expect from a 1987 9.9 4 stroke Yamaha?

    Tomorrow I will go to see and maybe buy the above mentioned outboard with remote control ,electric start and alternator, to use as a trolling kicker for a 19 foot Starcraft Islander on Lake Ontario. What should I be aware and/or beware of with these outboards? Is $ 450 a reasonable price if...

    Replacing trim senders on alpha drives.

    So I bought trim senders to replace the ones that should have been there on my 140 mercruiser and according to the booklet there should have been a color code like purple and blue on the connectors. Of course my connectors all had a perfect black. (Thank you Sierra). This is mostly about...

    1984 Islander with140 3 liter mercruiser yet again. When will I get it?

    140 horse piston rods.

    So I am busy rebuilding a 140 horse engine and the usual f-ups happen. So far I destroyed a piston and damaged a piston rod. Looking for a piston rod turns out to be a bit of a challenge. Specially when you do not know for sure which year the engine is from. As it turns out, from the mid sixties...

    Dual steering cable for kicker?

    I'm just wondering, Did any of you good people ever use a dual steering cable with one cable going to the I/O and the other to the kicker? If so, what were the pros and cons? Currently I use the E Z steer system and it is less than perfect. Rolmops.

    1984 3 liter mercruiser

    I am doing a valve job on this engine (my first ever) and I am wondering about the valve spring cap seal,that little rubber ring that sits on the valve. How important is it? can I go without or is that not such a good idea? If I need it,is it the same one that is on the 305 chevy block or is the...

    1984 3 liter mercruiser

    I found another 140 horse engine for my boat and right now I am in the middle of completely overhauling it. One thing I need to replace are the piston rings (the engine was frozen and although it came loose, the rings were stuck up to the point where they broke while being eased out. The rings I...
