    I am thinking of buying a used etec 150 for my ski boat. it's a 21 foot low profile ski boat with the original 1978 Johnson 150. I would prefer not to have the expense of changing the original steering cable over to hydaulic unit. I have been told that the newer etec might have to much torque...

    94 merc 60 tach not working

    I have a 1994 Mercury 60. The Tach was not working so I replaced it and its still not working. The switch on the back of the tach is set to 6p. When I turn the key on the tach moves but does not read with the engine running. Would the rectifier be the next logical step?

    Outboard paint

    I am restoring our old ski boat. Part of the project is a fresh coat of paint on the 1978 Johnson 150 outboard. Any recommendations for paint? Will it peel off if I don't use a two part. Can I get by with something out of an aerosol can? Thanks.

    1978 Johnson rebuild.

    While I have this motor off the boat I am considering doing some work to it. Engine runs fine now but has unknown hours on it. What would be required to up the HP a bit? New reeds perhaps, maybe carbs. Any ideas for increased performance on this engine. Thanks

    I am currently running a 15x17 aluminum prop. Making about 4600 RPM. I get some ventilation during turns and coming out of the hole if I'm not trimmed full down. I am thinking that a stainless prop may help some. Question is which one and what size. I've been looking at standard 3 blade OMC...

    I have a 1978 Johnson 150 with a 15x17 alum Michigan wheel prop. The boat will run 38 mph at 5300 rpm. However, at that rpm it will ventilate with turns or in rough water. If I trim down to about 4900 or 5000 rpm it will run without ventilation. Also on the hole shot it will ventilate unless I...
