    Really strange sound on start up - Mercruiser 3.0

    Agreed sounds like starter I would check there is no water In cylinder or does it turn over freely ? Otherwise starter is bad or maybe loose not allowing smooth retracting of gear

    2006 Volvo 5.7 osi-d crank no start

    Yes distributor needs to come out first, then usually some type of pry bar on the ends, they are just an oil sealing face with rtv Not a gasketed surface like between manifold and head throttle body can stay on

    2008 3.0L thermostat housing sensors

    What he said…and if your thermostat housing is that bad i would inspect your manifold and elbow carefully. I assume this is a salt water boat?

    Trailer Brakes or Not

    What Lou said - always hear Kodiak is the best or X brand is as good as Kodiak... I boat in fresh water and use my trailer twice a year so the tie down set up has worked great for me for 6 years. If I pulled it more than 10 miles to the launch I might be more worried about it...knock on wood...

    1990 Bayliner Capri 2050 5.0 V8 200hp

    Mercruiser 5.0 with an alpha one drive is an ideal power plant for typical bowrider of that size. Parts and service are plentiful and cheap, assuming it was reasonably well maintained, with a little annual maintenance will provide many more years of service to you. I think someone did floors...

    Trailer Brakes or Not

    If the trailer is a good deal buy and replace the brake system. When I bought my boat 6 years ago surge brakes on it were roached. I bought a Tie Down kit for less than $500. Yes there are better surge brake kits than tie down but you get the point.

    Shift Interrupter Switch Unhooked however...

    Yeah hook it back up. Is this a new to you boat? It likely means the shift cable was worn/dragging and killing the engine when shifting, so someone disconnected it... so you probably are in need of a lower shift cable and linkage replacement.

    You may want to call these guy to ensure you get the right one. There are two sizes listed for pre '85 two piece rear main seal engines. https://www.michiganmotorz.com/products/marine-parts-accessories/flywheels Summit racing is another good option as well.

    2003 Ebbtide Mercruiser 3.0 engine rattle? Normal?

    Ok do you have it at the spark plugs? If you have it at the center cable you must be loosing it inside the distributor cap. Maybe connection between center post and rotor is gone

    Oil pump

    With cold oil yes it will peg at idle. Your drill at 1200 is turning the oil pump at same speed as 2400 engine rpm as cam timing chain is a 2:1 reduction. Hot idle will be around 15 -20 psi or so.

    5.7 harness modification

    I think you are missing a jumper between the purple to supply fuel pump. It should get power off the starter during cranking , and also have a parallel supply off the purple that goes through oil pressure switch once it is running. Starter wire to fuel pump doesnt go through oil pressure switch...

    2.3l has 150psi across all cylinders, but small amount of water in oil.

    You can resurface the manifold to elbow selaing face either with a file or have a machine shop mill it or belt sander actually looks ok
