    Yamaha 2012 four stroke 115hp fuel prime while sitting for a couple weeks and won’t start…

    The primer bulb is not designed to hold pressure long term. It’s there simply as a means to get fuel to the fuel pump on “cold” start. The primer bulb is a simple hand pump with a simple (plastic) back flow preventer when held in the upright vertical position. Off vertical, the primer bulb...

    do vintage Johnson red gas tank contain lead paint ?

    If anything it would be coated with a Terne coating. A mixture of lead and tin used back in the day to prevent automobile fuel tanks from rusting.

    Yamaha F100 TLRY - 2 lower units but only one shaft fits?

    Looking at the parts breakdowns…. I’m seeing different part numbers for the 75 and 100 and the 100 has lists two different part numbers for the shaft. Don’t know the differences but your dealing with three possible part numbers

    98 Johnson leaking hydraulic fluid.

    Check the gasket or oring behind the mounting flange of the fluid reservoir.

    Dual Battery ... Wiring fail or I just don't understand?

    Using a battery maintainer as a “bulk” charger after use results in degraded performance and shorten life expectancy, especially for a starting battery designed to be discharged and immediately replenished. Manufactures recommend charging lead-acid batteries at a rate between 10% to 25% of the...

    Trailer wiring…how to improve grounding…

    I simply drill and tap the frame and install stainless grounding lugs as required. The tapped connections ensures continuity to the frame.

    excessive corrosion?

    If you swapped leads it would be + 320mV ;) It looks like you found your problem. Now all you have to do is find where the 320 mV is coming from. I suspect something is improperly grounded. Anything wired directly to the motor? Why is that? The idea of the exercise to eliminate stray...

    excessive corrosion?

    That you know of at the moment. Where does that bonding wire shown in the picture terminate? First, check for continuity between all three of anodes to make sure they’re functioning as one to dissipate any current presented. Ideally, you would want to run the following tests while the...

    Ritchie compass model 15

    What is wrong with it? My Explorer series leaked all the fluid out over the winter several years back. Shopped around and found a repair kit on the website below but decided to investigate my problem prior to ordering the kit. Turned out to be just the orings. Saved some money and ordered the...

    Automotive Ground Straps

    Ground loops probably account for 90% of all “noise” related problems reported in autos, boats and RV are a potential cause. If one component on the loop is noisy and the return current flows through shared ground connectors, this noisy component is then the source for an introduction of noise...

    Battery discharge. ...normal?

    What you’re missing is that a 12V flooded, lead acid battery is technically “dead” at 12.0 volts. At 10.5 V your down to 1.75V per cell and at risk of permanently damaging the battery. Some good information here on Depth of Discharge and battery longevity...

    Automotive Ground Straps

    Same principal applies to all electrical circuits. Even more critical in DC circuitry…communications, processors, digital logic and control circuits, etc. because of the signal levels in use...

    Battery discharge. ...normal?

    800 CCA is a meaningless measure of power for this discussion. The number your concerned about is the batteries Reserve Capacity. RC is the time in minutes that the battery can sustain a 25 amp load and remain above 10.5V. 140 Reserve Capacity = 140 Min. - (140/60)*25 = 2.333*25 = ~58Ah...

    Battery discharge. ...normal?

    Something isn't right. 3AH x 24 hours x 14 days = 1,008AH capacity? 3AH (125mA) per day x 14 days = 42AH capacity? To put this into perspective.......my Grp. 27 Deep Cycle are 110 AH What is the AH or RC rating of the battery in question? Bear in mind the AH and RC ratings are based on...

    Looks like the Rule 1100 sense pump is 0.25A per day. Glad mine is a good, old fashioned float switch
