Re: honda 7.5 runs rough with cover on
hi guys,<br /><br />was out on vacation for a couple days last week.<br /><br />got to play with the outboard on sunday<br />(in hopes of getting a sail in - even if i have to run with the cover off til i can get the sails up...)<br /><br />this was not to be.<br /><br />could not get her started?!?<br /><br />it ran great (except when the cover was on)<br />last week before i shut her down...<br /><br />i put in new plugs, as the old ones were wet<br />and flushed out the gas.<br /><br />tried again, and nothing...<br /><br />flushed out again.<br /><br />stole some fresh gas from my car<br />and started the outboard from a gatorade bottle...<br /><br />ran like a champ (after messing with the mixture screw again).<br /><br />while it was running, i checked the exhaust pipe and general vicinity for smoke, etc.<br /><br />could not see any smoke, or signs of leaks.<br /><br />there was a little water down in the well<br />where the exhaust pipe dissappeared.<br /><br />i poured in a little more water to see if i could see bubbles (detect a leaking seal?!?)<br /><br />nothing. but who knows.<br />the exhaust leak seems the most plausible...<br /><br />i found some openings in the case where<br />air would normally get in.<br />nothing plugged.<br /><br />one thing that i was unsure about is that<br />most of my exhaust gasses during idle<br />come out thru the two holes in the back of the shaft, well above the water line.<br /><br />if i cover these holes, i get major bubbling<br />below the prop.<br /><br />i thought that i might have some blockage in the lower exhaust outlet, so i covered the holes and revved a bit.<br /><br />no change.<br /><br />but now i'm not so sure the exaust out of these holes is normal?<br /><br />yes? no?<br /><br />my wife is picking me up a new gas can today.<br />if i get home early enough, i'll see if<br />bad gas was the culprit all along.<br /><br />thanks again,<br /><br />bob.d.
