Gents,<br /><br />My 1997 130hp 4stroke is running a bit rough at idle and slightly above (I notice a shake while at slow speed in the harbor.) I've recently tuned it up, basically changing the plugs and Racor fuel filter. I suspect there may be gunk in some of the fuel filters located under the cowl, but don't really know where to look.<br /><br />I do have the factory service manual, and could probably sort this out, but thought I'd seek the advice of you folks here. I know there were some service bulletins, but my motor was bought in Canada, and I have no real support locally (Alaska.) <br /><br />I did hit a small piece of wood on the water the other day, and while the stainless prop looks fine, I think I can see the slightest wobble in the prop shaft when I spin it by hand. It's going to the local Honda shop as soon as I can get an appointment (could be a week or two) to get checked out, but I'd like to deal with the fuel filters beforehand.<br /><br />Thanks a bunch, and feel free to get technical as I'm a mechanic and with the factory manual I can probably follow along with any advice given.
