    Mercruiser motor swap

    Gee I went out with a friend in his 18 footer with a 3.0 MerCruiser. It's vibration reminded me of those 90's 4 cylinder inline motors in small cars. It handled the boat OK. I had a similar boat with s 4.3LX. It was much smoother and much more powerful.

    My carb is obsolete.. Please help me repair/replace!

    Gee the first carb I saw clogged with varnish was in the fifty's. This was way before adding alcohol to gas was thought of. we also needed to add dry gas alcohol) to fuel tanks to absorb the water in winter. Today's fuel with alcohol eliminates a lot of that.

    Oil 4 stroke Mercury 115hp

    That motor likely requires a FC-W oil. Any oil rated as such is acceptable. Automotive multivis oils are generally not recommended.

    Mercruiser motor swap

    You might look up the weight of the V6 and V8 and see the difference. I expect it to be nominal. You might ask the experts if the motor mounts will match

    Motor lift plate

    manual Jackplates, right? They will move center of balance back a bit and the boat will set a bit lower in the water, at the stern.

    4 all y'all still shovelin snow

    New Jersey usually gets two weeks of extreme heat and extreme cold (by NJ standards) each year. Here at the shore that translates to about 5-7 days of whole house air conditioning per year. Obviously, the heat needs to be used from Nov until Mar/April.

    Plug wires for ‘71 Merc 20hp

    I looked up the plug wires from a '75 Merc 20. https://www.crowleymarine.com/mercury/oem-parts/outboard/1975/1200205/flywheel-ignition-coil-stator-and-switch-box-group-no-15?ref=28 parts for a '71 were not listed. Those plug wires look to be push in to the coil, with spark plug boots and...

    No dipstick on 1989 era 3.0L?

    So the old Merc manual says no multi vis oil, and you plan to use 15W40 multivis oil? It may even protect your motor, who knows? Gee, how about you visit a MerCruiser dealer or order the correct stuff from Amazon or someplace

    why is there oil in my bellows but pressure test holds 15psi overnight

    Look at the sealing surface of the yoke. If there is a groove, the seal will leak. Replacement will be in order.

    Garboard drain fittings are avail. A couple of thru bolts and some silicone could install it.

    89 force tilt and trim valve body

    Force was bought by Merc, and had Merc gearcases and electronics, at least. Any idea if the valve body is Merc or Chrysler? Crowleymarine has parts lists for both chrysler and force.

    No dipstick on 1989 era 3.0L?

    If the QS 25W-40 is NA, you can use SAE 30 detergent motor oil, for moderate climates. You also might look at the OEM recommendations, as there are a lot of FC-W motor oils (used in 4 cycle outboard motors) in my local Wallyworld that might be recommended. I never thought "Trying an oil", vs...
