    what is too long a time to run a gimble bearing ---

    I have been chasing down a few leaks prior to splash time and although i have found most of the problem i still have a dribble that drips down from under the Y pipe but I am thinking it is the driveline bellows. I checked the Y pipe while the engine and outdrive were out of the boat and it...

    1988 Starcraft w stuck steering cable

    I have locked up steering on my 88 starcraft w a 5.7 and cobra sterndrive. My problem is that the pin at the transom end of the cable is frozen and not wanting to come loose. Yesterday I wrapped my hoses up in tin foil and turned a heat gun on the yoke and pin along with a 6" clamp as tight as...

    I have posted part of this in my starcraft post but believe I should have done it here instead . I have a battery drain . While investigating the reason why some other things came up that make no sense to me. When I set the engine in ( 5.7 ) I tested the switch panel and most of it worked no...

    in contemplation of big boat restoration --

    I am nearly finished with my current resto of my starcraft and will soon put it up for sale locally . I seems to me that most restoration parts cost the same whether they are being used on a vessel that is 20 ft. or 35 ft. , so I am considering buying something in the neighborhood of a 34 ft...

    I need to touch up the stern of my boat and paint the Cobra outdrive soon . I went down to my local Paint Mart which is the only real paint store here thinking that I could get them to match the paint but they said they no longer handle paint for boats !

One side turned out good and one side I screwed up and it had too many runs in the primer that showed and I gouged the new paint up pretty bad in many spots getting the side window back into the...

    OMC 5.7 cooling system

    Can some one tell me why running a boat with a 5.7 in it with a closed cooling system would get salt corrosion in the exhaust manifolds and the Y tube if it were operated in salt water ? I have been told this several times here but I guess I'm just too stupid to figure it out. Seems to me that...

In fact the holes are nearly an inch closer than the mount holes...
