    Stringer/Foam question

    I have a 89 Citation boat. Is it possible that I have no stringers under my floor and just foam? Also, my foam under the deck always seems to be wet. How can this be? I thought foam didn't absorb water? Either way, she's due for a new floor soon.

    OMC Shift Adjustment - Stuart's Article

    I have a 89 OMC 4.3. In Stuart's article on adjusting an OMC shifting system, he has a "Shift System Adjustment" procedure and a "5 Steps of the Engine Shift Bracket Adjustment" procedure. How do the two relate? Do both have to be done at the same time? One before the other? <br /><br...

    OMC Transcom Bracket Shift Cable Adjustment

    I am reading Stuart's article on adjusting OMC's shifting linkage. It says, "Remove outdrive, replace the transom bracket shift cable if outer jacket is ribbed. Use the appropriate service manual." I don't know what "If outer jacket is ribbed" means. What is the outer jacket? My cable looks...

    Sealant on manifold gasket?

    Have a OMC 89 4.3 V6 and am finally putting the Mercruiser manifolds on tomorrow. I know the mating service between the block/gasket and exhaust manifold does not require sealant per my OMC manual, but do you put sealant on the gasket between the manifold and elbow? <br /><br /><br />Thanks

    Bolt instead of a stud?

    I converted the exhaust manifolds on my 89 OMC 4.3 to a set of Mercruiser exhaust manifolds. The old studs were too short for the new manifolds, and I can't find studs that are long enough and that have the same pattern (both ends are different). Can I use bolts to attach the exhaust manifold...

    I have a 89 OMC 4.3 V6. At the end of the season, I noticed some water in my plugs, pulled the valve covers, and also noticed the oil was white. From all the advice I read and got directly from posts, it seemed to either be the exhaust manifolds and/or the head gasket. <br /><br />I took the...
