    Cable Nut wont start

    "Righty-Tighty" right? When looking at the starboard side of the motor, the nut turns CW. I never saw a rubber washer inside the cable nut, however, I have certainly not seen everything. Maybe the tilt tube threads are buggered? Maybe someone replaced the tilt tube with something else? You...

    73 1150 fuel pump/flow question

    I had an 850 with those fuel pumps. I never had to do anything to them, so I am not real familiar with them. I would expect fuel to travel thru the upper furl pump to the lower fuel pump and to the upper carb. When you squeeze the primer bulb, I expect bottom and top carbs to fill first and...

    1976 mercury 850 idle problems

    OK, easy stuff first. Rectifier has 4 wire connection posts. Original Mercury rectifier had the -DC post connected to the motor frame ground via the mounting bolt. Aftermarket full wave rectifiers must have the -DC post grounded to the motor frame. The 2 AC posts get yellow wires from...

    Epoxy for gluing plywood?

    Laminating plywood face-to-face (vs end-to-end) can be done with titebond III which is supposed to be waterproof. I have never used it though. You can also use polyester resin and cloth to laminate them. If it is for a transom, stringer or frame, I would use the poly resin and cloth, as I know...

    Outboard exhaust drifts towards cockpit

    Looks pretty normal. You likely have a following wind, as the design of the boat is standard and wouldn't pull exhaust gases into the cockpit. You are lucky you have an optimax, as it is low emissions. You might make sure it is running properly, as smoke should be minimal, and fumes even less.

    Bonding Polyester to Epoxy - Will this Work

    Polyester resin will bond just fine to sanded, acetone-cleaned epoxy. Froggy is probably right that you do not need to use epoxy. Your boat was originally made from all polyester resin and cloth. Epoxy is only necessary for high strength repairs. For example, I had a hole knocked into...

    Shocks AND leaf springs on my trailer??

    Gee, bolt a piece of angle iron (for strength) to the axel with a U bolt. Now bolt the shock to the lower ubolts end. You will probably need to cut the top ubolt short and use a couple of washers on the lower U bolt for a spacer. Flat stock across the ubolt might be better, if the angled part...

    Bay boats offshore

    I am not sure what a "Bay" boat is. A 22 foot runabout is fine for fishing 1-3 miles into the ocean if the waves are comfortable. Heck the inlet is the worst part of the trip, especially with the wind against the tide.

    1959 johnson 50 super seahorse

    Racer, I had two Fattys. Both had rounded off shift dogs. With careful adjustment I could get a solid forward or reverse, but not both, due to wear on the shift linkage, dog and gears. I chose forward gear, and learned to get by without reverse.

    Mercury 90hp 1990 Leak

    Under the waterpump base is the driveshaft bearing. I do not think there are any seals to replace, once the pump base is out. Depending on the year of the gearcase, the driveshaft bearing has a taper. This taper faces either up or down to provide the correct clearance. They are hard for...

    Trim stuck in up position

    Make sure the manual tilt lock isn't jamming the transom bracket. They can rust and just get in the way. I think I remember my '77 Merc doing that. I think running it up some more, and then quickly down was the workaround. I doubt the inner seals are the issue. You do not want to open up...

    1959 johnson 50 super seahorse

    Those motors run very well and are very powerful at low RPM, due to the 70CU Inch displacement. They do not rev up very high, but you should see about 27MPH max speed. Their fuel recirculation system consists of dumping any fuel buildup in the intake manifold, overboard. With a bad/mis-tuned...

    Shocks AND leaf springs on my trailer??

    I have seen one other trailer with shocks. It had coil springs. It was from the 80's or earlier. Shocks and leaf springs were very common on American cars up to the 80s'. Earlier cars had them front and rear. Just about rear wheel drive product had them in the rear, until rear wheel...

    Mercury 90hp 1990 Leak

    The driveshaft oil seal is installed in the waterpump base. It is generally easier to replace the pump base, rather than changing the seal. Make sure to use the correct O ring and base gasket, as well as the correct gaskets on both sides of the wearplate.

    Forward and reverse help!

    A lot of Merc gearcase propshafts ratchet CW, not turning the driveshaft when in forward gear. Turning them CCW will turn the driveshaft, but can be hard to turn, because of the waterpump impeller doesn't like to spin backwards. The propshaft will turn the driveshaft both ways when in reverse...

    1967 johnson 33hp steering parts

    I will assume that your motor has the solid tilt rod, vs the hollow tilt tube. Go on a steering gear manufacturer like seastar and they should have the parts you need. You might get sticker shock. Used parts may be available

    Interior floor options?

    Gel coat will be fine under the carpet or exposed as the finished deck. it is hard to get a good finish with gel coat unless you spray it. An Imron or Awlgrip 2 part polyurethane paint may not peel under carpet, but I am not sure how it would be as a deck paint. It would probably be good...

    Sewing Machines

    I bought a Janome HD-3000 sewing machine recently. It will sew 6 layers of marine vinyl, and was $400 or so. Much better price than the professional machines, which are $1500 or more. I only do my own work, so the cheaper machine was fine. My grandmothers 1942 Singer factory machine was a...

    Sealing wood for motor mounts.

    For a fiberglass boat, I would recommend dry pressure treated solid dimensional lumber, versus plywood. Cut to shape, fiberglass to the hull and then coat with resin.

    Trim gauge off?

    Also, look for corrosion on the rheostat that s the trim sender. The copper can make bad contact giving an incorrect reading. BTW- it is best to trim the drive by sound and feel. It is easier and more accurate than a gauge.
