    1962 Merc 450 restoration ..

    Perhaps putting it in the Oven at 350 for an hour would warm up the Aluminium enough to let the race fall out, plus give you some Baked-on Enamel;)

    Bow rising and taking a long time to come on plane

    Welcome to iboats. Looking at the Video, it does look you the motor is too deep, maybe the bracket is too low and is catching water. Can you put it on a trailer, and take some pictures, at the level of the boat keel, with the engine down so as to show the where the AV Plate is located in...

    Need prop help with new boat

    Well a 5.7 has quite a bit more Torque than a 5 liter. I suspect you need a shorter prop, but before you start swapping props, what Prop is currently on it? What condition is the engine in? Compression Test. Is the spark strong enough at all cylinders to jump a 3/8" gap Is the Timing set...

    How do you shift gears?? Merc 9.9 Four stroke

    You merely twist the Grip, to move from Gear to Gear. Further movement increases speed. If you are asking how it does this, again the answer is to get the Service manual for that particular Motor. The how's and what's would be in there

    How do you shift gears?? Merc 9.9 Four stroke

    The Shifting is done by twisting the tiller handle? I suspect someone has been tinkering with the Idle Speed and/or Throttle Linkage, and that can lead to it being difficult to shift out of Gear You need the Factory Service Manual to get this system set up and adjusted correctly

    Evinrude year

    In the later years of that engine, they did change from the usual 2 coils under the Flywheel, Magneto, to a System that had 1 Coil under the Flywheel and a coil for each cylinder https://www.downloadservicemanuals.com/manuals/evinrude-johnson/wiring-diagrams/18-25_hp_electric_start_1973-76.pdf...

    5.0gi to 5.7 swap

    For me, calibrating a Carb, is far easier than trying to change an ECM program. Too many things to go haywire with the latter

    ‘83 Glastron Sx-190 looking for other owners

    My SX195, which is about 18 1/2 ft long, has a 5.7. It feels okay powerwise, actually a little under powered

    5.0gi to 5.7 swap

    Changing the Jets and/or Metering Rods, is rarely needed, but is routinely done to cover/hide other problems, same goes for all the different Accelerator Pump Delivery Curves that a Holley can be customized with. Where changes need to be made, are a little more complicated. Going to a different...

    4.3 Carb v 4.3MPI

    It has considerably more Torque. I'll take the 5.7 carb over a 5.0 liter FI. And by adding a few more CFMs to the Picture, it will also be making more HP

    Modern Engine Thoughts

    Another is much poorer Hole Shot. 4 strokes aren't as good for Waterskiing, unless you have several hundred Horsepower, pull as hard as a 60hp 2stroke did

    Gear Oil Questions

    Some people will insist that you can use Regular Hypoid Oil in the Gearcase, and others that will say that the Marine Oils are superior. I tend to be in the Latter group. These are small Gears, much smaller than what are found in Vehicle Differentials, yet they have to contend with very high...

    5.0gi to 5.7 swap

    If the ECM was Calibrated for a 5 Liter, it sure is not going to Calibrated for a 5.7, regarding Fuel Flow. As for the Cam, does the 5 liter Cam have the same Duration, Lift, Overlap, etc as the 5.7? What you need to do is get Part List for both Engines and compare, line by line, looking for...

    Inverted steering

    What was the boat at the "Mechanic's" for? So when you turn the Wheel to Port, does the outdrive pivot so the prop end goes to Port or to Starboard?
