    Lower unit noise investigation

    The driveshaft bearings on a lot of Merc gearcases are cone shaped. The cones can face up or down. Some that face down have a spring and pin on the top end of the driveshaft to push them down into the race. Some that face up rely on hydraulic pressure to push them into the race above. Since...

    modified leaning post? Bolster?

    Joe, Captain's chairs often have flip up cushions, just for the reason you want one. You might take a look at them and see how they work. Alternatively, simply install two of them replacing your current seat.

    modified leaning post? Bolster?

    Do you want the bolster behind your back or a cushion under your butt? Either way, make or buy the bolster (or cushion) and use some vinyl straps, and some snaps to hold it in place. Folded and sewed strips of vinyl fabric are pretty strong. Sew them to the bolster or cushion and install...

    Replacing Motor mounts

    Gee, which motor is that? I have replaced the upper motor mounts on my mercury OB, but not on my Johnny. On the Merc, the upper motor mount is sandwiched between the exhaust extension under the powerhead and the midsection. You need to pull the powerhead, and then remove some small bolts...

    35hp merc. Carb spring hookup?

    That spring looks to be bent. If I remember correctly, on my IL6 with the same carbs, the small straight tip should go into the carb shutter, and the loop end should go around a screw which is missing, in the hole at the base of the throat. The screw also held on the plastic grating. See...

    One last try

    A disk is child's play. I watched a guy get up deepwater on a slalom ski and a canoe paddle. He dropped the ski and skied on the canoe paddle.

    waterlogged foam in bowrider

    Gee, gel coat is just thickened poly resin. It is as waterproof as any other poly resin, plus it usually has cloth to help with waterproofing. Chips in gelcoat do not usually cause leaks. It takes more than that.

    waterlogged foam in bowrider

    Gee, if foam is wet, it needs to come out, and be replaced with dry foam. Of course, that means cutting out enough of the deck to dig out the wet stuff. You may find that more of the foam is wet (likely all of it), so when cutting out the deck, plan to cut it all out, and maybe you will not...

    25 HP Yamaha 4 stroke backfire

    Gee, is the timing correct? Does it advance when the throttle advances? The major difference when switching from working on a 2cycle motor to a 4 cycle motor is that the 4 cycle engine fires every 2 revolutions. i.e. After working on my 2 cycle outboards, I had a spark failure on my...

    One last try

    OK, I skied behind a 3.9HP Merc on a rowboat, on a picnic table top. It was more like surfing.
