The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
Put the boat in the water this afternoon, and surprisingly it ran great! Had a misfire at initial acceleration, but cleared up and ran as good as it ever has. Weather is a little cooler and lake temperatures have dropped about 5 degrees in the last week. I did not have any of the engine...
The temp at the upper head bolts using warm water at the muffs was 139 degrees F. I used the bolt head instead of the head to get a reading on a clean unpainted surface. This problem has been ongoing for the last 3 or 4 years, but since 90 plus percent of the time I run it no wake areas, I...
Fuel is fresh, tank is clean. I may have stumbled on a possible solution. I’ve discovered that this engine has a low power mode activated when temp sensor says the engine is running too hot. It doesn’t ever turn on the temp warning lite, but it makes sense since this problem is temperature...
Compression 125PSI both cylinders. My last repair was replacing the CDI with one I had replaced previously trying to fix another problem (it did not fix the problem) then or now. I removed and sanded and sprayed all terminal, grounds, and B+ connections also, and installed a different battery...
Luckily all the parts were spare parts I had from previous repairs on this and former engines. If the jets you are referring to are the ones hiding behind the carburetor drain plugs, I have run a wire through them and carb cleaner and compressed air. I think that I have got every passage clean...
The latest attempt did not correct problem. I have now replaced the stator, timer assy, coil, plugs and wires, power pack, and cleaned and checked every power and ground wire on engine, and cleaned all the contacts in the connectors. Just rechecked compression on both cylinders and have 125 PSI...
Engine idles fine all day, but when trying to get boat on plane, engine drops a cylinder and when returned to idle will miss fire for 20 to 30 seconds and then return to normal idle with no miss fire. I have replaced stator, ignition trigger, coil, plug wires, overhauled carbs, new plugs. Engine...
