    How do you guys mix Gas

    I had one of the LiPo Batteries for my Camera go Nuclear. I was on a Flight where someone else's Camera started to smoke. Good thing it wasn't in their Checked Luggage, and the Cabin Fire Extinguishers can put these out. They are tiny Bombs ticking away, I'm sure there will be plenty of Roadway...

    72 evinrude 65hp hydroelectric won't state in gear

    What about shifting out of gear? It was speced for Type C which is less Viscous. And yes. I know that Type C was the only Oil Marketed by OMC during the years of the Hydroelectric Gearcases

    1972 Cathedral Trihull Prop Size

    Some people just think cause it 'looks' the same, that it is the same. The 1.65 would have been fine on a 5 liter.

    78 Johnson 115hp Crossflow Stalls When Put into Gear!?!

    One thing to keep in mind, the Carbs are supposed to be fully closed at Idle, they are not adjusted for idle speed. Idle Speed is set entirely by Spark Timing, and there is NO spec for that, as it will vary depending on what prop is installed as it is adjusted/set while in gear. Different...

    78 Johnson 115hp Crossflow Stalls When Put into Gear!?!

    Regarding the Throttle Cable. Adjust it so it puts a bit of Load on the linkage to hold it against the Idle Stop as it sits in Neutral. Too much Preload will make shifting in and out of gear a pain. Then verify that the Throttle Plates are opening fully. However since you were mucking with the...

    How do you guys mix Gas

    When it came the V4 Crossflows and the Inline 6s, I give Mercury the nod. They were smoother, and gave better fuel Economy than the OMCs. My inline 115 had better Acceleration, higher top speed, and did so on less fuel, than the 140 OMC crossflow did on the same boat. That otta start a war

    How do you guys mix Gas

    The early(1974 - mid 80s)OMC 9.9s were about 12hp compared to the 11hp of Mercs 9.8. Good little engines, much stronger Gear Train than Mercs

    1978 Evinrude 140 V4 Only firing on 2 cylinders

    In 1979 the 85 did become a 99.6 in engine, and a 100hp appeared. In 1981, the 85hp and the 100hp were dropped and the 90 appeared

    1978 Evinrude 140 V4 Only firing on 2 cylinders

    Different jetting, some years not all, used larger Carbs, Crankcase Stuffers, different Heads, and Exhaust Tuning. You can turn a pre 85 115hp(1979 -1984), into a 140hp, by changing/adding those parts. In fact a 1979 thru 1984 90 hp can be converted to a 115 by some Machining of the Block, and...

    1978 Evinrude 140 V4 Only firing on 2 cylinders

    The 140 and the 115 up till 1985 used the same bore and stroke, and in most cases, the same block(1977 and maybe in 78 there were some differences in the Block). In 85 the 140 became a looper and few, if any parts interchanged between it and the older crossflow block.

    1978 Evinrude 140 V4 Only firing on 2 cylinders

    Welcome to iboats There are considerable differences between the 140 heads and any crank rated 115 heads(pre 1985) You compression numbers are poor. Could be the gauge, so try another. You might have what is referred to as a Frankenrude(a cobbling together of a bunch of parts from several...

    All our yard tools are still 2 strokes, We have a couple Dozen still unboxed, so as to have them when no longer on the market. Were able to get some High end Sthil and Husqu**** at very low Clear-out prices. Way cheaper than the Overpriced Electrics,
