    Briggs and Stratton Ignition Coil - Can Anyone Explain This?

    I'm working on a 10 HP B&S motor. The ignition coil is the "Magnetron" (solid state, no points) type. Here's what's confusing me. Based on my readings, in a good coil, the resistance between the kill switch lug and the coil frame should be 0 ohms. When installed, the coil frame is grounded...

    How to Remove a Briggs and Stratton Fuel Cut Off Valve Assembly??

    I'm rehabbing a B&S gas engine powered generator. The motor is a 10 HP B&S with a plastic fuel tank mounted above the entire assembly. The tank has a couple of gallons of what once (long, long ago) may have been gasoline inside. Outlet is on the bottom of the tank, through a cut off valve...

    Drive Shaft Spline Grease for Mariner

    Just realized I've been putting the wrong grease on the drive shaft splines of my 1982 30 HP Mariner. I've been using the stuff intended for the various zerks around the motor/mount. Took a closer look and realized that the splines require a high-temp, high-compression grease. I've had the LU...

    Tie Down Bearing Protector

    I finally decided to retire my leaking 35 YO Bearing Buddy bearing protectors. Got a pair of 1.98 D units by Tie Down Engineering at West (would have bought Bearing Buddy, but they didn't have them). Anyways, not much user info in the package. Unlike my old Bearing Buddy units, these have...

    Mid-day Sunday, Hanging at the Launch Ramp

    Had to go to West on Point Loma today. As usual, swung by the Shelter Island Launch Ramp to scope out boats/trailers/people/etc. Some notable items from about 15 minutes of hanging: Lots of activity. Makes me glad I can do my boating on non-holiday week days. Don't want to rub it in, but...

    Question on GFI for Electric Heated Spa?

    My spa was hooked up back in the 1980's, simpler times. It had a 40 A, 240 V circuit (4-wire) leading to the spa. The spa power pack had (still has) a GFI that protects the 120 V circuits (pump low speed, air pump, light), but not the 240 V heater. Last year I had the circuit upgraded to...

    Primary Wire for 120/240 Volts AC?

    I'm doing some repairs on my electric spa heater. This will involve replacing some pieces of #10 and #12 stranded wire. The only stranded wire in those sizes I can find in my local hardware store/HD store is Primary wire - which I understand is usually used for DC applications in boats, autos...

    Question on Bunk Modifications

    Going to add Glide Sticks to my bunks and have a couple of questions (I'll be pulling the bunks to add the sticks). First, see photo(s). The bunks are canted in slightly towards the center of the trailer, to clear the stiffening ridges. As a result, the hull bears on the outside edges of each...

    Re-Torque Head Bolts?

    Appears a number of you do this as part of annual maintenance. Seems like a good idea, but I'm not sure exactly how to do it. I think I read somewhere that if I come by every year and just tighten them to the torque spec I'll be increasing the actual torque on the bolts each year. So, what's...

    Anybody Fish San Diego Bay?

    ..... and care to share good spots/gear recs./techniques? Been going out once in a while for past 2 years with minimal success - mostly in the eel grass area between the end of Shelter Island and America's Cup Harbor. Not a big deal, since it's nice just being out there for awhile. But...

    Stripped Thread on One of Water Pump Mounting Holes - Helicoil?

    So, my impeller replacement job hit a couple of stumbling blocks. Latest, stripped thread on one of the pump mounting holes in the LU. I'm thinking Helicoil or equivalent to restore threads. Anybody done this? I'm thinking the SS Helicoil is the way to go. Yes/no? Or will that create a...

    What Kind of Steel for My Water Pump Bolts?

    Have '82 30 HP Mariner, Japanese made. Water pump housing has an extension to accommodate the long-shaft configuration. Rebuilding the water pump and noted, on re-assembly, that the bolts that hold down the pump housing only have 1/8" purchase on the threads. Looks like the bolts that were on...

    New Impeller Plate Different?

    I've got an '82 30HP Mariner. Purchased a water pump kit from iboats (3'd party, OEM listed as NLA on Crowley site). See attached. Water intake in new impeller plate is smaller that in old plate. Seems like it would reduce cooling flow. Significant? Or no? Going to install it and see how...

    Interesting Find in My Water Pump Housing

    30 HP Mariner, 1982. Cooling flow problems so pulled LU and found impeller shot. The plate and cartridge insert showing some scuffing so I decided to get the complete kit while I still can. Pulled the insert out of the water pump housing and saw a little knurl of "stuff" near the water outlet...

    Five for Five on Cooling Problems

    I often see posts on OB cooling problems. I'm no expert, but, I can recall five instances of my motor overheating/lack of cooling water flow. Every time the problem has come back to the impeller. Latest instance - went out to fire up my motor and no flow through tell-tale. Pulled the LU and...

    Neat Sanding Block at HF

    About $6. Advertised to take 6" stick-on sanding disks (which HF sells). Works better with hook-n-loop disks (which HF does not sell, but Lowes does). Sponge-like material, so adapts to irregular surfaces. Sides have about 1/2" radius for sanding fillets, etc.

    Anybody Ever Set Tile in 5200 or Similar?

    Making a small, rolling, outdoor cabinet. Top maybe 2'X2' and I want to tile it. Convention (from what I've read) is plywood top, thin set, screw down cement board, apply membrane then thin set and tile and finish w/grout. I'm thinking of drawing on techniques/materials I've used with my...

    Need Help Understanding Navigation Light Requirements

    Now getting to the time where I'm actually spending more time using my boat than working on it. Since I might be out after dark, as shorter days approach, I'm looking at installing navigation lights. My understanding is that for my boat, 15'-6" aluminum skiff w/outboard, I need one of those...

    Almost a Tragedy

    On a routine "tour" of the Shelter Island Launch Ramp yesterday I noticed a 15'6" Bayrunner alongside a large RIB tied to one of the piers. Since I have the same boat I strolled over to take a closer look - get ideas for improvements/share experiences/etc. As I got closer I noticed the...

    What's Wrong With My Tire?

    Saw this little beauty at the Shelter Island Launch Ramp today. Doesn't show in the picture, but, looks like it has been like this for a long time. Is this why some of you guys have dual axle trailers?
