    5.0l mercruiser 2003 670 hrs puffer

    If it does not smoke enough to foul spark plugs then you can use it that way but it is possible to replace the valve seals on a Chevrolet small block without removing the cyl heads, there are a few different ways to do that, if you search on you tube you will see. I put a pair of reman cyl...

    Cone clutch??

    TRANSOM MOUNT - 1988 OMC Stern Drive 5 504APRGDP | Crowley Marine this is the OE part list and part #. With these the folds are asymmetric the side with more folds goes down, to flex more when the drive is tilted. Also the side that goes on the gimble housing flange has a rib that fits in a...

    Cone clutch??

    There were 2 different cone clutch drives branded OMC but a 1988 will be the standard Cobra dog clutch. If you have it use your model number to order parts. cone clutch drives: All OMC Cone Clutch (Daddy King) has impeller in upper gear housing like standard Cobra, used with big block engines...

    What are the essential tools to keep on board?

    If you have a Volvo DP you need a special wrench to change those props, but if you have the standard single prop you can swap a prop on the water if the design of the boat allows it. I have been able to do it on my F/W with the OMC Cobra. If I tilt it all the way up and tie the prop wrench onto...

    Converting 5.0 mpi to closed cooling

    Its things like this that make me keep the old one! Set of points & condenser and a Quadrajet rebuild kit (less than $100 parts) and there you go. The "benefits" of technology are greatly over-rated.

    What are the essential tools to keep on board?

    3 bolts and the plastic cover over the impeller comes off, 3 more bolts and the whole thing comes off of the upper gear housing. I have one all ready to install if needed.

    What are the essential tools to keep on board?

    The boat sits on a salt water mooring. If you suck up a lot of sand because you went into the shallows (only happened to me once) that can grind up an impeller. The ace in the hole is the OMC Cobra impeller design. If you tilt the drive all the way up & you’re careful you can change it with the...

    Converting 5.0 mpi to closed cooling

    At least here in Long Island (definitely salt water maybe not as salty as Fla) your block and heads will not rust through in only 10 years, when I had my engine apart in 2017 it had been used in salt more than 15 years (15 just by me, not sure about previous owners but I bought it here so it...

    Engine replacement

    If it was a failure to winterize I think you can assume the engine was full of water as well as the exhaust manifolds. So the block, heads, intake and exhaust is likely cracked. One big hunk of scrap iron. If you put in an engine that's in good condition with no internal corrosion consider...

    Can you start these in cold temperatures out of water?

    If that’s what you have those were great easy to maintain engines. Should be easy to get at drain plugs vs those on a V6 or V8. The wood rot issue really depends the climate where the boat lived all those years. If it was stored in a very dry climate like the arid southwest it could be fine...

    Engine replacement

    Lol Good one there! Yes get a manual and learn the right way. These forums are for filling in the blanks in manuals that are written for professional mechanics. You need to educate yourself first though. Otherwise you will ‘learn’ by making expensive mistakes.

    Great work there glad to hear it worked out! The aftermarket is what makes running old equipment practical.

    Dry joint exhaust pros/cons

    Agreed if I could adapt it to my OMC rigged 4.3 for sure I’d use it. Definitely one of Mercs better ideas. You still have to replace the elbows and maybe the manifolds after 7 or so seasons in our LI salt water but that whole time you don’t have to worry about that gasket between the manifold &...

    Can you start these in cold temperatures out of water?

    Agreed you can run an outboard in freezing temps just make sure the motor is tilted down so it drains but any raw water cooled inboard motor MUST BE DRAINED after running in freezing temps or if freezing temps are anticipated. Thousands of people in the south just got a very expensive lesson in...

    Can you start these in cold temperatures out of water?

    If you are thinking of doing this what you need to do first is learn where all the raw water drains are on whatever engine you are working on. Sucking AF up the outdrive will not cut it because idling a cold engine on the water hose in cold weather the thermostat probably won’t open. This will...
