    Sell Electronics With Boat or Separately?

    Good advice! I bundled everything I had associated with the boat and the repairs and modifications I had made (pulling out a few things I could actually use). Typical Craigslist ad was something like: Boat, motor & trailer. Motor runs good. $XXXXX." My ad had almost a page of add-ons...

    Sell Electronics With Boat or Separately?

    Now that's a persuasive argument :)

    Sell Electronics With Boat or Separately?

    Getting ready to put my boat (15'-6" Bayrunner) on the market. I have some modest electronics that I've used with it. Basically a handheld marine radio, fish finder that mounts on the console and a portable Garmin GPS. Wondering what best strategy is: sell as package or sell boat and then...

    Durable Tarp?

    Hey, guys. I'm thinking some of you have some experience with tarps for covering your boat. My boat is well covered, but I have a piece of equipment that is exposed to E. San Diego County sun, rain and wind that I'm looking to protect. I've been using the HF silver tarps, but they crap out in...

    What Do the Plugs Say?

    I took a look at the ignition circuit schematic (which I should have done in the beginning). See attached. One coil with one primary and one secondary winding feeding two plugs. Looks like it has to fire both plugs with one near TDC and one near bottom. Based on the diagram, doesn't seem to...

    What Do the Plugs Say?

    Now that I've got (at least for now) the cooling issues resolved with my '82 Mariner I'm looking at another issue. Motor is 30HP Mariner 30A, CD ignition, 2 cylinder, single carb and relatively new (about 30 hours) plugs. No. 1 (upper) cylinder plug seems to look like it should (light tan...

    Free Boat??

    See: https://www.sandiegouniontribune.com/news/public-safety/story/2019-09-06/ Looks like a Bayrunner Baja 18. Might be up for grabs :)

    Yikes, $92 for a Thermostat!!

    I've got a Mariner 30A, vintage 1982, needing a new thermostat. Looked up the Mercury version and it's about $92. Seems a bit high since it seems most other thermostats run in the $20-$30 range. I don't know if Sierra makes a version of my thermostat. I do know that my motor is basically a...

    Where to Look For Cooling/Water Flow Problem?

    Motor: 1982 Mariner 30A. Wasn't used for about a year. Ran OK when last used. Started it up a week or so ago, in a barrel. Ran OK at idle and about 1200 rpm for maybe 10 minutes, with normal temperatures (based on my cylinder head sensor) and good flow from tell-tale. Then, running at...

    Ahhh, Impellers

    The latest in my 10 year saga of fighting impeller issues with my 82 Mariner 30A. Was running it in a barrel yesterday and noticed tell-tale flow at idle was way down from what I last remembered. OK at higher RPMs but actually set off my overheat alarm after a few minutes at idle. My first...

    Backing the Trailer

    Backing with my old Tacoma was getting harder and harder. I now have a Honda Ridgeline that will make my old crank-the-neck-around and do it no longer a possibility. The Ridgeline does have a rear-view camera that I can already see will be great for backing up to the hitch. I'm wondering if...

    Sizes for Nesting Tubing?

    I'm planning a hitch mounted "T" rack for my truck. Planning on using round tubing, two sizes, so one nests/slides/rotates inside the other. Wondering what gap between the ID of the outside tubing and OD of the inside tubing I should be looking for to insure free movement without binding, yet...

    Protect Inside of Steel Tubing From Corrosion

    I've constructed a number of projects using steel tubing. I've pretty well nailed the process of treating, priming and top coating the outside of the tubing to prevent rust/corrosion. However, I've never figured out what, if anything, to do to the inside of the tubing. I've tried spraying...

    Water Pump Housing Installation Tip

    Maybe old news or a non-issue for many. However, as I continue to age (why is that?), arthritis and loss of hand dexterity have made installing the pump housing over the impeller increasingly difficult. Turning the drive shaft and pushing down on the pump housing, then lining up the bolt holes...

    Mariner Water Pump Gasket Material

    My '82 Mariner, 30 HP, eats impellers - as a result, I end up replacing the impellers way before any wear on the pump housing/base plate assembly. Most of the time I end up trashing the gasket when I disassemble the pump. So far, the only way I've been able to find replacement gaskets (the one...

    Flat Screen TV Wall Mount?

    We're looking to replace our 20 year old TV. Ideal would be a 70". Because of space constraints and optimum viewing angles we would need a wall mount that would allow the 70" TV to swing to a minimum angle of 42 degrees to the wall. ​Difficult to determine from wall mount specs/descriptions...

    Use Old Computer Monitor for Inspection Camera Display?

    Once again I turn to my best technical resource. I've got an older inspection camera (a Whistler GB8803, to be precise). It has a small, 3"x3" or so monitor but allows for hooking up a larger monitor. ​I've got an old LED computer monitor with analog input via a 15 pin D-sub (male) cable...

    Lock Nut on Idle Adjust Screw? Would This Be a Problem?

    The idle adjust screw on my old Mariner vibrates out of adjustment after awhile. I usually notice this on the water when it's a PIA to re-adjust (have to remove cover and part of electric choke assembly to get at the screw). And, when the idle speed gets below 500 rpm it doesn't pump enough...

    Pressure Build Up in Fuel Tank During Hot Weather

    I've got one of those EPA compliant 6-gallon plastic fuel tanks that don't vent to the atmosphere. I have been leaving the fuel line connected to the tank during storage. When it gets hot her (say the 90's) the pressure builds up in the fuel tank to the point where, if I don't remember to...

    Solar Landscape Light Rehab

    My wife bought a couple of decorative solar lights at a garage sale. Only $5, but they are kind of neat and she really likes them. They are made with the LED lights on a decorative "stalk" with a cord running to the solar unit (see photo). Problem is, the solar unit on one of the lights is...
