    How do you screw into fiberglass/gelcoat without chipping?

    When in industry, people who worked certain substances used a peculiar bit. It may be referred to as a "sheet metal" bit. Rather than having a chisel point where the cutting edge starts at the center and as it penetrates the material the bit is slanted and works its way out to the final...

    Better hole shot for a jon boat.

    Turning Point brand Hustler are high performance aluminum props and some are ported. The port decreases the density of the water flowing over the blades on the hole shot allowing the engine to rev up faster hence get on plane faster......like lowering the prop's pitch just for the hole shot...

    Prop Swap opinions...

    The tab is fixed as is the prop. Neither move from the set position. I have run as close as 1/4" with no problems.

    Boat performance

    In the Mercury manual covering larger engines it says that you should expect problems if compression is below 120 PSI. Don't know the specs on OMC and low HP engines but besides loosing one cylinder, you could be low on power. I don't see determining if you are operating on both cylinders is a...

    LOWER END OIL CHANGE

    I never measured it but the sealing washers in rubber or fiber are compressed at time of installation. That compression easily acts as a "lock washer" to hold the screw in place.

    Thrust Washer Question - Yamaha Performance 3 Prop

    Well back to the box of thrust washers. You can tell when you get a good fit.....taper on washer fits the taper on the prop shaft, nothing loose, no wobble, prop doesn't touch gear case.

    LOWER END OIL CHANGE

    Just my opinion: OUCH! I have an impact driver and set of tips. Only time I used it was for backing out stubborn fasteners as the torque value from a hammer strike is undefined.

    Prop is making thumping / clicking noises when hand rotated (video)

    If you knew about the action of the clutch dog previously, and now you are realizing a different noise, after an altercation, then by all means check it out.

    Prop is making thumping / clicking noises when hand rotated (video)

    Ok how about engine and the remainder of the drive train since they are all linked together.

    Scupper below water line?¿

    lemme guess: Drain for a bait well, or built in cooler, possibly a deck drain on center console boat. Surely don't want backwash filling them up.

    Prop suggestion for 1995 60 hp Merc 2 cycle

    Did you also post this question on the Marine Engine/Mercury Mariner forum. If so, I answered it there.

    Thrust Washer Question - Yamaha Performance 3 Prop

    Shouldn't be any play in the prop to prop shaft interface, and the thrust washer has to fit snugly in the rear of the prop and the ID is sloped to marry to the slope in the prop shaft to ensure exact alignment. I bought a used prop from a long time in business marine dealer. Upon attempting to...

    Prop is making thumping / clicking noises when hand rotated (video)

    From the rear trying to turn the prop CCW results in resistance and the prop doesn't want to turn.....that is for F gear. Slowly turning the. prop CW and watching the prop in relation to the LU casting and listening, you will notice the prop moving away from the gear case slightly and then...

    Scupper below water line?¿

    I had a Crestliner that had flappers on the splash well. Idea was to keep returning seas from coming in and filling the well when coming off plane, yet allow any water collected in the well to easily drain out. If yours are under water, I'd say that you are mighty stern heavy.....like some...

    2004 Mercury 115 2 stroke - oil injection block off plate

    I think you "fixem for a living" based on your posts I have read over the years. I fix mine to suit me using my capabilities, experience and assets....max performance, minimum cost and hassle. If I were doing it for someone else, especially for compensation, methodology would be more akin to...

    2004 Mercury 115 2 stroke - oil injection block off plate

    1. I don't know what gold means...having had both of those (90 and 115) mine showed no signs of any gold. 2. As I got older I boated less and less. As a result when it was time to start the engine at the launching ramp. the starter would turn the flywheel and in the process ensured that oil...

    2003 Mercury ELPTO won't rev above idle

    You apparently have binding somewhere. Get a manual and do a "Link and sync" which sets up the carbs and the linkage to the throttle control. Otherwise you might have a lot of hours on the engine and time to renew the plastic clips.

    LOWER END OIL CHANGE

    I always used a screwdriver sized to adequately fit the slot in the plug. Installed the new fiber washer and with two hands on the screwdriver, got it good and tight. Same for the vent screws you remove to help in draining, and ensuring the LU is full of oil. Never had a problem.

    Tell tale not peeing

    On some Mercs, the little hole in the front of the midsection or LU...forget which is the pickup for the speedometer. Easy to tell as if that's what it is, there will be a small black hose down there and following it up it goes to the Helm with the electrical cabling to operate the speedometer...
