    Mercruiser 888 no go over 3000rpm

    Are you getting full ignition advance . Assuming you have a mechanical advance, verify with timing light you are getting 28 or more degrees total advance by 2800-3000 rpm. Not sure of the specs for your engine but that is a rough ballpark

    mercrusier 350 MAG MPI coupler problem

    Make sure you have the correct input shaft (only one I knew was shorter is the older inline six ones) and alignment is good and it will work.

    mercrusier 350 MAG MPI coupler problem

    If the alignment is correct the coupler will last the lifetime of the boat. If this is the third coupler there is an issue that needs to be fixed either transom engine mount of stringers are damaged, someone is hitting stuff or running over anchor lines, or alignment is off. Were these OEM...

    Carb or worse?

    Yeah that is odd he took out thermostat usually when that is done it is a work around for a blockage somewhere in cooling system . If the cooling is working ok it should run very cool like 120 without thermostat

    Brown dust on exhaust and spark plug look

    Plugs look good to me jetting is correct in my opinion. The stain by idle relief ports may be more from the water salts etc drying on . youmay try using something to remove water deposits and lime residue from sinks etc see if it comes off

    Alpha 1 Gen 2 Weak Link

    Alphas get a lot of shade thrown their way but the reality is they work great for its intended purpose smaller (less than 23 ft) boats less than 300 hp. Light, easy to maitain, and inepxensive comparatively to replace- perfect for typical bowrider marker. Take care of them and they will...

    88 sea ray with 3.0 mercruiser.

    If your idle passages are clogged then there is no fuel going to it. Any hangin up linkage will not help needs to move freely as a closed choke will eventually foul the plugs and kill the engine. What does your fuel filter look like. Most of these issues are from boats sitting and getting...

    Boat lift options?

    Nice work. I think you probably have way more battery capacity than needed. I converted my R&G vertical aluminum lift to dc power by taking iff the hand crank and using a 12 vdc winch like offroaders put on their front bumper. Use a group 31 deep cycle battery and 7 watt solar charger. Use the...

    Dont think youll see any appreciable difference between these, but best fuel economy is typically just after you get on plane so likely the one with the lower planing speed /rpm

    88 sea ray with 3.0 mercruiser.

    Where in terms of rich/ lean did you set the choke element? After two minutes i wouldn’t expect it to be open much.loosen the screws, start engine , Turn the choke element so when engine is warm it is fully open. Verify linkage is clean and not hanging up. carb may need rebuilding but start...

    U-Joints for 2003 Alpha One Gen 2

    Ok before this gets as worthless as an oil thread… the spicer cross diameter was .640” so as rick said they will work just fine. The spicer was more $ than the moog so id go that route.

    Mercruiser engine year

    I think you have to put an O or 0 in front of the M and it will come up . My engine is OM694685 is a june 2003 build ( in a 2004 boat) so your serial being earlier numerically would line up with a 2001-02 year
