    What fuel to run?

    Your motor is made to run on regular fuel with or without alcohol. I would run fuel from a high volume gasoline station, as these usually have fresh gasoline and are without water in the fuel. Stabilizer can be useful for off-season storage but is unnecessary if you use the boat every couple...

    Max Throttle on 1995 Evinrude E150 GLEOM

    Those super-fast 'toons have hundreds of HP in their engines. A single 150HP motor will not push the average 24' 'toon any more than 25 mph, in my experience.

    Leaky boat

    I/O engines can leak water when they run, when they are tilted up, and of course, when they just sit. It would be helpful to know if she leaks under any of those conditions. A good plan of attack would be to launch the boat, motor out for a few minutes and then turn the motor off and monitor...

    Prop for Homemade Pontoon

    Gee, I would have thought that with enough power, the 'toon would have planed better with the flat bottom pontoons, than with round bottom pontoons.

    lower unit/ impeller gasket seals

    If the waterpump cover ss liner is scratched, replace it. If the water pump base is scratched (it is melted) and should be replaced as well. If reusing the pump base, be careful to replace the water pump base driveshaft seal. In either case, sand the driveshaft to make is clean and smooth...

    Is this going to be a problem?

    I assume the prop has a modular hub? You might also check that to make sure it matches your engine make and model.

    lower unit/ impeller gasket seals

    You will need to look at the seal kit. Usually the shift seal is an aluminum bushing, with an oring inside it and a gasket on the fitting above the threads. The prop shaft seals are a PIA to install. With any luck you will not need to replace them. The waterpump base driveshaft seal often...

    lower unit/ impeller gasket seals

    Not normally. I would not yank on it though. The shift seals are avail at a lot of places like Amazon as well as boat motor parts places.

    Max Throttle on 1995 Evinrude E150 GLEOM

    Gee, most 'toons of about 24 feet only go 22mph with 150HP OBs on them. What kind of 'toon do you have that will go 40-50MPH?

    lower unit/ impeller gasket seals

    The shift shaft bushing with the seal should unscrew from the gearcase. I ground down a 1/2" black pipe connector into a spanner to unscrew the bushing, but you can unscrew it with a punch as well. Test the gearcase with a few PSI of air pressure and some soapy water to determine where the...

    Leaky boat

    What kind of engine? If I/O, there are lots of places for water to leak into the bilge. If outboard, there are less places for leaks to occur, with the engine mounting bolts, and thru hull fittings being the most likely. Also, look for small cracks in the hull. The strake on my SeaRay...

    lower unit/ impeller gasket seals

    You will want to pressure test the gearcase to determine what is leaking. You can use a bicycle pump and the tube from the lube pump to do that. Often the shift shaft seal leaks.

    Why does gearcase have threads and bolts?

    The grooves in my '98 Johnny 150HPV6 60* motor are concentric. That begs the question why? Maybe an expandible jig to install something or test something in the gears.

    HYDROFOIL

    Baja's are performance boats. Performance boats usually have plenty of power and do not need whale tails. The whale tails are normally used on underpowered and stern heavy boats. They can create extra drag if not installed properly, or if the motor is not installed at the correct height. On...

    Automotive Diagnostic Tool

    Gee, a noisy belt tensioner is usually pretty easy to diagnose. It usually sounds like a squirrel taking a beating under the hood. When was the last time you replaced your spark plugs?

    Why does gearcase have threads and bolts?

    Right, the Johnson gearcase just has the threads like a Mercury OB gearcase. My OEM service manual shows the 5/16" threaded rod and puller as the correct tool to pull the bearing carrier.

    Steering cable stuck?

    Spray the steering rod and wipe it off until it is clean. If someone banged on the end of the steering rod, it could be mushroomed. That would need filing or sanding to get it small enough to pass thru the tube.

    Why does gearcase have threads and bolts?

    There are threads in the gearcase housing, exactly where Mercury puts theirs, to hold the bearing carrier nut. I was not able to find a bearing carrier puller that uses those threads. All of them that I found had hooks for the bearing carrier plus the center bolt to push on the propshaft.

    Mercury 115 2 stroke won’t idle and runs rough.

    A real clean spark plug can be a sign of water infiltration into the cylinder. Did you tell us the year of this motor? Is it a 2+2 motor?

    Why does gearcase have threads and bolts?

    My '98 Johnny 150HPV6 (60*) has bolts holding the bearing carrier, plus unused threads at the terminal end of the thru hub exhaust housing. Any idea why those threads are there? Maybe for a bearing carrier puller? I have threads on my Merc gearcase (as is usual), which hold "doughnut" shaped...
