Well, went searching for the trim limit switch...

    I have a 188 302Mercruiser, 1974 model. When running the engine on muffs I notice water coming out of two ports on the sterndrive. These ports are located just below the gimbal ring. Why is water coming out of these ports and not all of it going out through the exhaust? Is this normal or...

    Another Riser/Cooling Question

    This weekend I took my risers off to clean and inspect and to replace the gaskets. This is the first time since I have owned the boat, and of course out of the 12 bolts I had to remove, 8 of the heads broke off. :mad: <br /><br />Anyway, getting to the point of discussion. I noticed that the...

    Aluminum Intake Manifold

    I found a brand new Weiand X-CELerator intake manifold at an unbeatable price. However, this manifold is aluminum. Will this aluminum intake stand up to the harsh effects of salt water better than the cast iron manifold?

    4 Barrel on 2 Barrel Manifold

    I am looking for some opinions on placing a 4 barrel carburetor on a 2 barrel manifold. Will there still be a big difference in fuel consumption and engine response and performance? Or will I be wasting my money without switching to a 4 barrel manifold?<br /><br />The reason why I am asking is...

    Firing Order - Ford 302 - 888 Merc

    After looking through my shop manual last night at the firing order on my 1974 Ford 302 Merc - 888 model I was a little confused. My manual states that the firing order should be 13726548, yet my manifold has casting numbers for the firing order 15426378. I assume that last one is correct...

    888 and 225

    What are the noticeable and unoticeable differences between the 888 and the 225 Mercruiser Engines? Obviously the 225 has more horsepower probably due to the ca. But if the outdrive serial numbers fall in the same catagory as an 888 and a 225 in the same year range, how would you tell the...

    Electronic Conversion Kit

    I own a 1974 mercruiser stern drive with a 302 ford engine. I was curious as to whether there is a conversion kit for the distributor from points to the electronic version? If so, is it worth changing over if I have to reset the timing on the engine, or do I? Do you have to replace the entire...

    Cooling system

    Hi all,<br /> :confused: <br />Can anyone explain the cooling system on an inboard? I have done some research and realized there are two ways of cooling-closed looped with a heat exchanger-or open looped with raw sea water. I have recently taken my father in laws' boat out of storage to get...

    trouble with idle

    I have a 1974 40HP 2cyl. Johnson. I have recently had the carb rebuilt by an outside source about 5 months ago. It ran smooth at idle, the best it ever has, as soon as I got it back and put it on the water. Here lately, it is starting to die out at idle. I have adjusted the idle speed valve...

    I want to install a dash mount tachometer on my 1974, 2 stroke, 40HP, Johnson that was not originally equipped with one. Is there a tach with leads that attach to the terminal board that will read the AC current, or one that attaches to the coil or spark plugs? What type of tach should I be...

    Magneto

    I recently performed an inspection of my magneto and armeture plate on my 1974 40hp Johnson. Everything looked fine: points, coils, etc. After reinstalling the magneto are there any adjustments that need to be made or checkpoints to look at since the time timing sets itself with the cam on the...

    I am replacing the water pump in my 1974 40 hp, 2 stroke Johnson. The water pump kit that I took out apparently was an updated model since the water pump kit I purchased to replace was manufactured completly of steel. I was told the purchased kit was the factory kit. However, I am a little...
