    My little fleet at rest

    Two old boats that I love. One is my departed dad's fishing rig, the other a mentalcase fast recent project. Guess which I hop into most.

    2006 9.9m chronic fuel system problems

    Dual purpose questions for my merc colleagues. I have a repeat patient in my sick-bay, a fairly well maintained 4 stroke 9.9hp merc that appears to have great difficulty with regular gas. (~10% booze) I'm now on it's third carb kit and second fuel pump in 3 years. Not Merc's fault they put hard...

    Prowler by Cooper Yachts refurb

    1986, 16.5ft bow rider lake boat/tender I scooped for a song. Manufactured in Pitt Meadows BC by a legendary west coast boat builder named Forbes Cooper. She was hauled out of a lake, an unsecured tarp kinda thrown over and left to fend for herself in south Cariboo weather for 3 years. Lots of...

    Timing and octane ratings

    How much advance could one safely add when using 94 octane fuel, any? My J70elcos appears to absolutely love running at a fat 20 degrees btdc, instead of the stock 19 and I use Chevron super supreme 94. After 2 hours on the water today my plugs still generally appear a healthy dark brown and...

    Occassional dead cylinder

    1985 J70ELCOS, aka a 70hp Johnson. After sitting for a month or so the engine clearly has dropped a cylinder and idles very rough. I replaced the spark plugs and performed some tests and eventually went for a quick shake-down run at a small but extremely busy lake which revealed a normal running...

    Thermostat relief valves ('85 70hp Johnson J70ELCOS)

    I am just putting the finishing touches on a major service, but I decided to go a little bit further and attempt to break-up the salt crystals that must have built up in the water-jackets etc over the years the engine was plying the salt-chuck. I am satisfied I have removed a lot of quite...

    Bit of a rant

    For the first time in years I will be ordering parts from someone other than iBoats. I priced out a bunch of parts 2 weeks or so ago, but today iBoats wants to charge me twice for shipping because the engine parts and prop are now in 2 different locations. Sorry, not my problem. What a stupid...

    Somewhat Steamy Exhaust

    '85 Johnson 70 VRO (Deleted) CJ70ELCOS. The motor has been used in the chuck (salt water) from new and had been stored for the past 3 years. Properly stored I should add, in that it was flushed regularly and fogged etc when layed up. It did sit out on the mooring buoy through the summer months...

    VRO conversion -- over time

    I had a fella ask me an interesting question last week while I was converting his old style '85 VRO 70hp to pre-mixed gas. (no wire type) "Won't the oil side of the pump wear out faster now that the oil flow has been stopped?" he asked. I responded that I have been converting these VROs for some...

    Maximum safe Seafoam limit?

    I am considering using Seafoam to decarbon my 6R78B but wonder how much is safe to add? Up until lately I have never used any sort of "canned mechanic" aside from Techroline and Howes, but do not want to have to deal with rusted head bolts to decarbon the old fashioned way. I keep hearing...

    6R78B powerhead bolt fell out

    I was motoring along the lake on Monday when all of a sudden the noise level went up a fair bit on my '78 6hp Johnson. After stopping and inspecting I noticed that one of the powerhead bolts had fallen out. The bolt in question was located where the stainless one with a washer is shown in the...
