    Axle rating help.

    If you really want to upgrade, ditch the Springs and get a Torsion Axle. It is basically an Independent Suspension. I changed to a Torsion Axle in 20015, and it is a much nicer towing experience

    What is the main cause of an outboard that's hard to start again after it's already warm

    You need to verify that the Spark can jump a 7'16" gap repeatedly. If it can't then there is a Problem. Check all connections, and grounds, including those to the engine block This one is a long shot, but it can cause Difficulty in starting. A bad Crankshaft Seal under the Flywheel.

    On my I/O the Sending unit is quite a ways back on the tank(makes for a very inaccurate fuel gauge) and is about 2 ft forward of the front of the engine itself, pretty much under the front of the Bench Seat

    With the Engine Cover/Sunpad open, can you see the Fuel Lines, and Fuel Fill Hose/Pipe go under the Floor/Deck? If so, can you get a Mirror and Light down there to try and see the location of the Sending unit?

    3.7 to 4.3 swap

    Lake Boating where the waves get a little nasty is where I boat. The Boat actually holds 22(statue)mph very well. I run at that speed a lot as it allows me to stand up and get some cooling on Hot Days, 20c and above. It is propped to hit the upper end of it's rpm range, with a 1.51:1 gearbox. It...

    3.7 to 4.3 swap

    Small engines have to spin higher Rpms to get the same power that a bigger engine gets at lower rpm. The Extra Torque from the greater Displacement is what bigger boats need most. Given a Choice between a 220hp 4.3 and a 220hp 5 Liter, I will take the 5 liter(though I consider it too small for...

    3.7 to 4.3 swap

    I agree, with Bondo. Nothing Less than a 5.7 in 21 footer. It is less likely to take forever to get on plane, and it will have a Higher Top End which is always nice if you have to get somewhere in a hurry, or away from a Storm

    Trailer lights troubleshooting help

    Since you didn't put the Trailer on the Ball, you might not have a ground, often the ground wire to the Tow Vehicle breaks but the Lights still work, cause it is using the Hitch to complete the Circuit. 50 yrs ago my Dad never used a 4 pin connecter for trailer wiring, He used the 3 Prang...

    OMC 4 blade propeller - AMC-444

    A four Blade loads the engine more, so it doesn't always make for better hole shot

    OMC 4 blade propeller - AMC-444

    It is a Prop for an OMC outboard, it is not an OMC Prop. Michigan Prop 4 blade 10" Dia 11" Pitch. It would fit on the Big Twin type of Outboards; 25hp(1951-55), 28hp, 30hp(1956), 35hp(1957-59), and 40hp(1960-76, and the later commercial models).

    Broken Driveshaft

    Before you spend money on another gearcase, make sure the Powerhead is not damaged. Scored Cylinders/Pistons and warped Heads are common Features of overheated engines. I suspect that Overheating would be one of the reasons the previous owner sold it

    '22 Mercury 115 Pro XS, best prop?

    I would verify that the Tach is set correct first. Myself, I would ditch the 4 blade, and use a 3 blade, that by itself will raise the PRM, reduce drag, and increase Speed. Dropping Pitch will certainly make for quicker Acceleration, as for top speed? Dropping one Blade will increase top speed...

    What is the cause of only getting 75% power at full throttle , but 100% with a bit of choke .

    An off idle stumble is often caused by a Lean Idle Circuit. There might be a bunch of Gum/Varnish in the Area, which requires removal of the carb, and removing the Welsh Plugs and cleaning all the stuff out. I have used Power Tune, or Combustion Chamber Cleaner added to the gas, as it is more...
