    Oil Pan

    It is a GM pan but I think the marine ones have baffling to control oil sloshing. @Scott Danforth may know the GM part number which is the best way to order it. I would get the GM part prime it really well and coat it with bed liner or rhino liner I think that is what folks do to cut down on...

    est ignition on a 1989 4.3 liter cobra.

    dont over think it, either location will work fine As long as your wires are long enough. i think MM just bolted it to the cylinder head . Volvo used the est on 4.3 s they may have a bracket that mounts the coil to back of engine or exhaust

    2006 Mercruiser 4.3 no power to Fuel Pump

    Antisiphon valve is in fuel line on top of fuel tank. It takes a slight cracking pressure to open. Idea is it will prevent a leak in fuel line from siphoning the fuel tank into the bilge… problem is they can stick and not open impeding fuel flow. If the fuel pump is running but no fuel was...

    Engine siezed

    Probably an uphill battle either way, but if the manifold/riser connection was bad you would see rust streaking and evidence inside the manifold and rust in exhaust ports and on exhaust valves. Would ask to see that. Leaving an engine outside under plastic wrap is a bad idea... if there is...

    2019 Sea Doo Fish Pro Wear Ring (small marks)

    The factory manual will give a wear limit for clearance between the ring and the impeller, but agree yours looks fine. you will notice on holeshot especially towing a tube or skiier that it will slip more , engine revs up ski doesn’t go any where. I think i did mine around 140 hrs , so should...

    Hello all, I want to install a remote oil filter mount for my 4.3 V6, is it neccessary to replace the filter mount bypass valve?

    You want it to bypass flow when the filter is restricted, otherwise engine is starved for oil

    Alpha outdrive upper and lower interchangeability

    On alphas the gear ratio is done in the upper. So yes a 4 cylinder will have a 1.98:1 gear ratio Vs the likely 1.62:1 (could be a 1.50) you have. Soupper is useless. Lower would swap over, if you want a second spare…

    Engine removal thoughts

    In addition to the other suggestions and auto wrecker with a boom is not a bad option. That is essentially what I had when I did my repower. Was the way to go, spent more time getting work done than screwing around. It took him longer to set the machine up than do the lifts. Edit- didnt see...

    Making engine beds

    Would agree it would be tight might have to cut some glass to access it. Would do a remote oil filter set up and the seats/compartments on the side - what is in there ? when you open can you cut a hand hole in the side for access to drain plugs and spark plugs My grandfathers boat has similar...

    Hello all, I want to install a remote oil filter mount for my 4.3 V6, is it neccessary to replace the filter mount bypass valve?

    this is up in the oil filter adapter on my 5.0 https://www.michiganmotorz.com/oil-filter-adapter-sbc-bbc i believe that is the relief valve.… not sure i understand the desire to remove it. Yes maybe a higher pressure relief is more desirable, but yours with some maintenance has held up well...

    Hello all, I want to install a remote oil filter mount for my 4.3 V6, is it neccessary to replace the filter mount bypass valve?

    If I recall there is an allen head holding it in the oil filter housing , so it would be upside down when engine is installed. Take the filter off and use a mirror...
